We are given a scenario where the user records TV broadcasts in .mpg format, one file per hour. They have a playlist for VLC but need to manually switch to the next file every hour. The user wants to know if it's possible to link the playlist with the channel's EPG (Electronic Program Guide) so that VLC can automatically play the next file when the current one ends. However, note that VLC does not natively support automatic playlist advancement based on EPG data. Instead, we can think of alternative solutions: 1. **Creating a long playlist**: We can create a playlist that contains all the .mpg files in order. VLC can be set to play the next item in the playlist automatically. But note that the user might not want to watch all the files in sequence? Also, the user might want to start at a particular time and then continue without manual intervention. 2. **Using a script to update the playlist**: We can have a script that monitors the current time and updates the playlist to include the next hour's file when the current one is about to end. 3. **Using VLC's "Continue playback" feature**: VLC has an option to continue playback of a media that was stopped at a certain position. But that might not help with multiple files. 4. **Concatenating the files**: We could concatenate the files into one large file, but that might be inefficient and not practical for long recordings. Given the constraints, the most straightforward solution is to create a playlist that includes all the files for the day (or the desired period) and let VLC play them in sequence. This way, when one file ends, the next one starts. But the user mentions "epg на канала", meaning they might want the transition to happen at the exact time when the next program starts (according to EPG). However, note that the recordings are hourly, so the transition would be at the top of the hour. If the EPG information is strictly aligned with the hour, then the hourly files would naturally align with the program boundaries. But if the user wants to switch at the exact moment the next program starts (which might not be exactly at the hour), then we would need to adjust the transition time. However, the recordings are fixed hourly. So unless the user can record in a way that the files are split according to the EPG (which is more complex), we have to work with the hourly files. Therefore, the simplest solution is to create a playlist of the hourly files for the period you want to watch, and set VLC to play them in order. Steps for the playlist solution: 1. Create a playlist file (e.g., `daily_playlist.m3u`) that lists all the .mpg files in order for the day. Example content: ``` /path/to/recording/2025-07-16_00-00.mpg /path/to/recording/2025-07-16_01-00.mpg /path/to/recording/2025-07-16_02-00.mpg ... ``` 2. Open this playlist in VLC. By default, VLC will play the files in sequence. 3. If you want to start from a specific hour, you can create the playlist starting from that hour. But note: if the user starts watching at 10:30, then at 11:00 the next file should start. However, with a fixed hourly playlist, the first file (for 10:00) would be playing until 11:00, and then the next (for 11:00) would start. But if the user starts at 10:30, they are in the middle of the 10:00 file. Then at 11:00, the next file would start. That is acceptable. However, if the user wants to start at the beginning of a program that starts at 10:30, then they would need a recording that starts at 10:30. But the user's recordings are hourly. So unless the recording system can split by program (using EPG) and not by hour, we cannot have a file that starts at 10:30. Alternative: use a script that generates a playlist on the fly, starting from the current time and including the next files. But the user still has to start the playlist at the beginning of the hour? Not necessarily. They can start at any time, and the playlist would include the current hour's file and then the next ones. We can create a script that: - Determines the current time and the current hour's file. - Creates a playlist that starts from the current hour's file and then appends the next hours. - Then starts VLC with that playlist. But note: if the user starts at 10:30, they will start at the beginning of the 10:00 file? That might not be desired. We can use VLC's ability to start at a specific time offset. So we can have the script also calculate the offset (30 minutes in this case) and start playing from that offset in the current hour's file. Here's a plan for a bash script (assuming Linux server): 1. Get the current time and date. 2. Calculate the current hour (in 24-hour format) and the minute. 3. The current file would be for the current hour (e.g., if current time is 10:30, then the file for 10:00). 4. Create a playlist that includes: - The current hour's file, then - The next hour's file, and so on for as many hours as desired. 5. Start VLC with the playlist and set the start time for the first file to the current minute and second. Example script: ```bash #!/bin/bash # Directory where recordings are stored RECORDINGS_DIR="/path/to/recordings" # Get current time current_date=$(date +%Y-%m-%d) current_hour=$(date +%H) current_minute=$(date +%M) current_second=$(date +%S) # Calculate the offset in seconds (for the current hour's file) offset=$((10#$current_minute * 60 + 10#$current_second)) # We'll create a playlist for the next 24 hours? or until the end of the day? Let's do next 24 hours. playlist_file="/tmp/vlc_playlist_$$.m3u" # Start from the current hour and go until 23, then next day? But we are only doing 24 hours. for i in {0..23}; do hour_num=$((10#$current_hour + i)) # If hour_num >= 24, adjust if [ $hour_num -ge 24 ]; then next_day=$(date -d "tomorrow" +%Y-%m-%d) hour_num=$((hour_num - 24)) hour=$(printf "%02d" $hour_num) # Check if the file exists? We might not have tomorrow's recording yet. # But for the script, we just add if exists? or break? # Let's break after 24 hours from now? We are only doing 24 files. filename="${RECORDINGS_DIR}/${next_day}_${hour}-00.mpg" else hour=$(printf "%02d" $hour_num) filename="${RECORDINGS_DIR}/${current_date}_${hour}-00.mpg" fi # Only add if file exists if [ -f "$filename" ]; then echo "$filename" >> "$playlist_file" fi done # Start VLC with the playlist, starting at the offset for the first file vlc "$playlist_file" --start-time=$offset ``` Note: This script is a starting point. It might need adjustments for handling the next day and for the fact that the recordings might not be available immediately (e.g., if we are at 10:30, the 11:00 file doesn't exist until 11:00). So we should only add files that exist? But the script runs at the start. So for the current hour and past hours, the files exist. For future hours, they don't. We should only add files that are available? Or we can break the loop when we find a missing file? We are already checking for existence. But note: the next hour's file might not be available until the hour starts. So the playlist might only have the current hour and the past hours? That might not be what we want. We want to include the future files as they become available? But VLC will not dynamically update the playlist. Alternatively, we can run the script every hour? But that would restart VLC? Not ideal. Another idea: use a HTTP live streaming (HLS) approach? But that might be overkill. Given the complexity, the simplest solution is to create a playlist for the entire day (with the files that are already recorded) and then manually add new files as they are recorded? But that requires manual intervention. Alternatively, we can have a daemon that updates the playlist as new files appear? But VLC doesn't reload the playlist automatically. So, for now, the script above will play the existing files for the next 24 hours starting from the current time. But it will not include files that are not yet recorded. Therefore, when the next hour's file is recorded, it won't be in the playlist. So the playlist will stop at the last available file. To overcome this, we can create a symbolic link to a dynamically updated playlist? Or we can use a FIFO? Another idea: use a script that periodically updates the playlist and then signals VLC? But VLC doesn't support that. Alternatively, we can use a different player that supports dynamic playlist updates? Or we can use a more advanced media center solution like Kodi. However, the user is using VLC. Given the constraints, the best option might be to use the initial playlist of the entire day (if the day's recordings are already scheduled) and then set VLC to play. But note that the future files don't exist. So we cannot add them until they are recorded. So we might have to start with the available files and then manually add the new files to the playlist and reload the playlist? But VLC doesn't have a way to reload without interrupting playback. Therefore, the most practical solution for now is to use the script above to start from the current time and play the available files until the end of the day (or until the last available file). Then, when the next hour's file is available, the user would have to manually add it to VLC? or restart the script? That's not seamless. Alternatively, we can use a different tool that can concatenate the files as they arrive? For example, using `ffmpeg` to concatenate the files and stream to a pipe? But that might be heavy. Considering the trade-offs, the original request to use EPG might be overkill and not directly applicable because the recordings are split by hour, not by program. In summary, I propose: 1. Use the script above to generate a playlist starting from the current hour (with offset) and including all the available hourly files for the rest of the day (that have been recorded so far). Then, when the next hour's file is recorded, the user can manually add it to VLC? Or they can run the script again? But that would restart the playback. Alternatively, we can create a cron job that runs every hour to update the playlist and then use a VLC extension or API to add the new file? But VLC doesn't have a straightforward way to do that from the command line without interrupting playback. Given the complexity, it might be acceptable to have a break at the top of the hour and then the user manually starts the next file? Or use the playlist and just let it stop at the last available file, then the user manually adds the next file when it appears. But if the user wants a fully automated solution, they might need to look into a more sophisticated recording setup that records in a single file or uses a media server that can handle the concatenation. Another idea: use a symbolic link that points to the current hour's file and then changes to the next hour. But you can only have one file. Then, at the top of the hour, change the link to the next file. But VLC would stop when the current file ends? And then the user would have to open the next file? Or we can have a script that updates the link and then signals VLC to play the new file? Again, VLC doesn't support that without restarting. After research, I found that VLC has a feature to "Play and continue" when a media ends? But that is for the same file? Not for a different file. Alternatively, we can use the VLC HTTP interface to control it remotely. We can have a script that, when the current hour's file is about to end (say at 59th minute), it sends a command to VLC to add the next file and play it. But note: the current file is 1 hour long, and the user might start at any time. So we cannot rely on the time remaining. We can calculate the remaining time in the current file and set a timer to add the next file just before it ends. But that requires knowing the exact duration of the file? And the file might not be exactly 1 hour? But the user records hourly, so they should be. Steps for the VLC HTTP method: 1. Enable VLC HTTP interface: in VLC, go to Tools -> Preferences -> Show All -> Main interfaces -> HTTP remote control, and set a password and port. 2. Start VLC with the current hour's file and the offset. 3. Then, have a script that runs in the background and checks the remaining time of the current playback? Or sets a timer for (60 - current_minute) minutes? But if the user started at 10:30, then the file will play for 30 minutes. So we set a timer for 30 minutes. But note: the start time might not be exactly at the half hour? So we can use the VLC HTTP interface to get the current time and remaining time. We can write a script that: - Gets the current playback time and the total length of the current file from VLC via HTTP. - Calculates the remaining time. - Sleeps for the remaining time minus a few seconds. - Then adds the next file to the playlist and sets it to play next. But this requires the VLC HTTP interface to be enabled and the script to be running. This is complex but feasible. Given the time constraints, I'll provide an outline for this solution: 1. Start VLC with the current file at the current offset, and enable the HTTP interface. 2. Write a script that: a. Connects to VLC HTTP interface to get the current status (using curl and XML output). b. Parses the current time and length of the playing file. c. Calculates the remaining time: `remaining = length - current_time` d. Sleeps for `remaining - 10` seconds (to add the next file 10 seconds before the end). e. Then, adds the next file to the VLC playlist (via HTTP) and issues a command to play the next item when the current one ends. But note: VLC doesn't have a direct command to play the next item in the playlist when the current ends? It does by default if the playlist is set to continue. So if we add the next file to the playlist, then when the current file ends, it will automatically play the next. Steps for the script: - Before starting, we know the current file and the next file. - Start VLC with the current file (with the offset) and an empty playlist? Or with the next file already added? We can add the next file at the beginning? But then if we start at 10:30, the next file (11:00) is in the playlist, but we don't want to play it until 11:00. But VLC will play them in order. So we can start with the current file and then add the next file later. But if we add the next file after the current file is about to end, then VLC will not have a next item until we add it. And then we can set the playlist to continue. So the script would: 1. Start VLC with the current file. 2. In the background, start a script that: - Calculates the remaining time (either by the file duration and current position, or by the fixed hour: if the file is hourly, then the remaining time is (60 - minutes_into_the_hour) minutes minus the seconds). - Sleeps for that time minus a buffer. - Adds the next file to the playlist via the VLC HTTP interface. Here's how to add a file via HTTP: ``` curl -u :password --data "command=in_enqueue&input=file:///path/to/next_file.mpg" http://localhost:8080/requests/status.xml ``` And then VLC will automatically play it after the current file if the playlist mode is sequential. But note: if the user started at 10:30, then the current file (10:00) will play from 10:30 to 11:00. We want to add the 11:00 file at about 10:59:50. Then when the current file ends at 11:00, the next file will play. The script for the background process: ```bash #!/bin/bash # This script runs in the background after starting VLC. # Password for VLC HTTP interface VLC_PASSWORD="yourpassword" VLC_HOST="localhost:8080" # Current file and next file current_file="/path/to/current.mpg" next_file="/path/to/next.mpg" # Calculate the remaining time in the current file: # We know the file is one hour long, and we started at a certain offset. # But if the file is exactly one hour, then remaining = 3600 - offset # But the offset is in seconds. # However, we started at offset=$offset (calculated earlier in the main script) # We can pass the offset to this script. offset=$1 # in seconds remaining=$((3600 - offset)) # We want to sleep for remaining - 10 seconds sleep_time=$((remaining - 10)) sleep $sleep_time # Now add the next file curl -u :$VLC_PASSWORD --data "command=in_enqueue&input=file://$next_file" "http://$VLC_HOST/requests/status.xml" ``` Then the main script would: - Start VLC with the current file and the offset. - Start this background script with the offset as an argument. And then the next file will be added 10 seconds before the end of the current file. We can extend this for consecutive hours. But note: the next file might be for the next hour, and the next next file for the hour after that? We can have a chain of scripts? Or we can have one script that after adding the next file, then calculates the next next file and sleeps again. But that gets complicated. Given the complexity, and since the user's request is to have it work for the next file initially, we can start with this and then extend. Alternatively, we can have a single script that runs indefinitely, and after adding a file, it then waits for the next hour (or the next file's remaining time) and adds the next one. But that requires knowing the next file in sequence and its duration? But they are hourly, so we can assume 3600 seconds. We can do: ```bash #!/bin/bash # This script runs in the background and enqueues the next file repeatedly. VLC_PASSWORD="yourpassword" VLC_HOST="localhost:8080" # The current hour's file (the one that is playing or just added) and then we want to add the next one. # We are passed the first next file and then we keep going. # But initially, we are passed the current hour's file and the offset? No, we want to add the next file for the current playback. # Let's assume we are called with the next file to add and the time to wait. # But we want to chain: after adding file A, we then wait for file A to be about to finish and add file B. # How about we have a function that takes a file and the time to wait until we add the next file for that file. function add_next { current_file=$1 sleep_time=$2 sleep $sleep_time # Determine the next file: from the current file name, we can parse the date and hour and then increment the hour. # Example: /path/to/2025-07-16_10-00.mpg base=$(basename "$current_file") date_part=$(echo "$base" | cut -d'_' -f1) hour_part=$(echo "$base" | cut -d'_' -f2 | cut -d'-' -f1) next_hour=$((10#$hour_part + 1)) if [ $next_hour -eq 24 ]; then next_date=$(date -d "$date_part tomorrow" +%Y-%m-%d) next_hour="00" else next_date=$date_part next_hour=$(printf "%02d" $next_hour) fi next_file="${RECORDINGS_DIR}/${next_date}_${next_hour}-00.mpg" # Add the next file to VLC's playlist curl -u :$VLC_PASSWORD --data-urlencode "command=in_enqueue&input=file://$next_file" "http://$VLC_HOST/requests/status.xml" # Now, we want to wait again for the next file's playback to near its end? But we don't know when it will start playing. # However, we know that the file is one hour long. So we will wait for 1 hour - 10 seconds. # But note: the next file might not be available immediately? We assume it will be available by the time it is added. # We then recursively call add_next for the next file, with a sleep_time of 3590 seconds (1 hour - 10 seconds). # But we must background this so that we can chain multiple hours. add_next "$next_file" 3590 & } # For the first call, we are waiting for the current file to near its end, and then add the next file. # The current file is passed as the first argument, and the sleep_time as the second. # We call it in the background so that the script can exit after setting up the first next file. add_next "$1" "$2" & ``` Then in the main script (the one that starts VLC), after starting VLC, we call this background script with the current file and the first sleep time (which is `remaining - 10`). This is a recursive background process that will add the next file just before the current one ends, and then set up the next one, and so on. Note: This is a complex solution and might have issues with many background processes. We can rewrite it to be iterative without recursion, but the idea is there. Given the complexity, the user might prefer to use a media center like Kodi or Plex that can handle series recording and play them as a series. But if they want to use VLC, this solution is feasible but requires careful setup. In conclusion, there are multiple ways to approach the problem, but none is trivial. The simplest is to create a playlist of the available files and let VLC play them in sequence, accepting that future files won't be in the playlist. The most automated is to use the VLC HTTP interface and a background script to enqueue the next file just in time. I leave it to the user to decide which trade-off they prefer. За да автоматизирате възпроизвеждането на поредица от .mpg файлове във VLC, така че да преминава автоматично към следващия запис без ръчно превключване, и да използвате EPG (електронен програм гид), имате няколко възможности. Ето решенията: 1. Автоматично преминаване със стандартен плейлист (без EPG) Ако файловете са именувани последователно (напр. 2024-07-16_20-00.mpg, 2024-07-16_21-00.mpg), VLC може автоматично да преминава към следващия файл: Създайте текстов плейлист (.m3u или .xspf) с всички файлове в правилния ред: plaintext /път/до/записи/2024-07-16_20-00.mpg /път/до/записи/2024-07-16_21-00.mpg ... Отворете плейлиста във VLC. ⚙️ Активирайте: Tools → Preferences → Show settings: All → Playlist → ✓ Continue playback 2. Интеграция с EPG (автоматично превключване според програмата) За да се превключва точно в началото на следващото предаване (според EPG), ще ви трябва външен скрипт. Ето примерен подход: Стъпки: Инсталирайте зависимости (напр. epg2vdr или xmltv за обработка на EPG данни). Подгответе EPG данни във формат XMLTV (напр. epg.xml). Създайте скрипт (напр. на Python), който: Анализира EPG файла, за да намери точните времена на предаванията. Генерира динамичен плейлист, който включва файлове според EPG. Превключва файловете във VLC през неговия HTTP интерфейс. Примерен скрипт (Python): python import vlc import xml.etree.ElementTree as ET import time import os # Конфигурация EPG_FILE = "/път/до/epg.xml" RECORDINGS_DIR = "/път/до/записи" VLC_PASSWORD = "парола" # зададена във VLC: Preferences → Main Interface → HTTP # Зареди EPG данни tree = ET.parse(EPG_FILE) root = tree.getroot() # Намери текущото предаване и следващото now = time.time() next_program = None for program in root.findall(".//programme"): start = int(program.get("start")) if start > now and next_program is None: next_program = program break if next_program: # Генерирай име на файл според времето на следващото предаване next_start = time.localtime(start) filename = f"{next_start.tm_year}-{next_start.tm_mon:02d}-{next_start.tm_mday:02d}_{next_start.tm_hour:02d}-00.mpg" filepath = os.path.join(RECORDINGS_DIR, filename) # Изпрати команда към VLC да пусне следващия файл import requests requests.get( f"http://localhost:8080/requests/status.xml?command=in_play&input=file://{filepath}", auth=("", VLC_PASSWORD) ) Как да пуснете скрипта: Включете VLC HTTP сървър: Tools → Preferences → Main Interface → ✓ HTTP remote control (задайте парола). Стартирайте VLC и пуснете текущия файл. Пуснете скрипта като фонова задача (напр. с cron или systemd timer) да проверява на всеки 30 секунди. 3. Алтернативно решение със софтуер за медиен сървър Ако предпочитате готово решение: Използвайте Kodi с добавка като PVR IPTV Simple Client: Конфигурирайте го да чете EPG от източник (напр. XMLTV URL или файл). Добавете записите като "локални файлове". Kodi ще ги организира като телевизионни предавания и ще превключва автоматично. Важни бележки: Именуване на файлове: Файловете трябва да съдържат датата и часа в името (напр. 2024-07-16_21-00.mpg), за да могат да се свържат с EPG. EPG източник: Трябва да имате достъп до EPG данни за канала (чрез предоставяне на файл или URL). Времева синхронизация: Сървърът трябва да има точен часовник (използвайте NTP). Ако имате нужда от помощ с конкретна конфигурация (напр. как да генерирате EPG), моля, уточнете! #EXTINF:-1 group-title="Eurosport",Eurosport 20250205 00 http://xxx.xxx.xxx.xx/archive/1994/20250205-00.mpg #EXTINF:-1 group-title="Eurosport",Eurosport 20250205 01 http://xxx.xxx.xxx.xx/archive/1994/20250205-01.mpg #EXTINF:-1 group-title="Eurosport",Eurosport 20250205 02 http://xxx.xxx.xxx.xx/archive/1994/20250205-02.mpg ..... We are given an example of a playlist that links to hourly recordings of a TV channel (Eurosport) for a specific date (2025-02-05). The user wants to have a playlist that automatically plays the next hour's recording without manual intervention, and also to integrate with the EPG of the channel. The playlist format is an M3U playlist. Each entry has: - `#EXTINF:-1` with a title that includes the channel name and the date and hour of the recording. - The URL to the .mpg file. The problem: In VLC, when one recording ends, it doesn't automatically go to the next one? Actually, by default, VLC should continue to the next item in the playlist if you have the setting enabled. But the user says it doesn't. So let's check the VLC setting first. However, the user also mentions the desire to have the playlist tied to the EPG. This suggests that they want the playlist to be generated dynamically based on the EPG schedule, so that when the current program ends (which might not be exactly on the hour), the next recording starts at the correct time. ### Proposed Solution: We can break the problem into two parts: 1. **Ensure VLC plays the next item in the playlist when the current one ends.** - This is a setting in VLC: Tools > Preferences > Show settings: All > Playlist > check "Continue playback" - Also, make sure the playlist is in the correct order. 2. **Generate a dynamic playlist that aligns with the EPG schedule.** - Instead of having fixed hourly segments, we want to create a playlist that switches at the exact time when the next program starts (according to the EPG). This might mean that one recording file (which is one hour long) might be split into multiple segments if it contains multiple programs, or conversely, a program might span multiple hourly files. However, note that the recordings are stored as one file per hour. So we have: - 00.mpg: from 00:00 to 01:00 - 01.mpg: from 01:00 to 02:00 - etc. But a TV program might start at 00:15 and end at 01:30. So we would need to play: - From 00.mpg, starting at 00:15 until the end of 00.mpg (which is 01:00) - Then continue with 01.mpg from 00:00 (i.e., the beginning of the file) until 01:30. This requires: - Knowing the exact start and end time of each program from the EPG. - Creating a playlist that has multiple segments for one program if it spans two files. ### How to do it? We can create an M3U playlist that uses the `#EXTVLCOPT` directive to set start and stop times for each segment. However, note that VLC does not natively support automatic concatenation of segments with different start/stop times in a single playlist item. Instead, we can use the `concat` demuxer or create a complex playlist with multiple items for one program. But a simpler approach is to generate a playlist that jumps to the next program at the exact time it is scheduled, regardless of the file boundaries. This requires having a player that can switch streams at a given time. VLC can do this via a Lua script or by using the `cvlc` command line with a playlist that has timed items. However, this is complex. Alternatively, we can pre-process the recordings and cut them according to the EPG, but that is time-consuming. ### Alternative Approach: Use a Dynamic Playlist with Timed Items We can create an extended M3U playlist that specifies the exact duration for each program. Then, when one program ends, the next one starts. The issue is that the program might span two files. We can use the `#EXTVLCOPT:start-time` and `#EXTVLCOPT:stop-time` for each segment. For a program that spans two files, we would have two consecutive playlist entries for the same program? But that would break the continuity. Another idea: use the `concat` protocol to virtually concatenate the two parts? But VLC supports concatenation via the `concat` demuxer. We can create a text file for each program that lists the file segments and then use that as a playlist entry. Example for a program that runs from 00:15 to 01:30: Create a file `program1.txt` with: ``` ffconcat version 1.0 file '20250205-00.mpg' inpoint 15:00 file '20250205-01.mpg' outpoint 30:00 ``` Then the playlist entry would be: ``` #EXTINF:-1, Program Name concat:///path/to/program1.txt ``` But note: VLC supports `ffconcat`? Actually, VLC uses the avformat demuxer which supports concat protocol? It does support the concat protocol as described in the FFmpeg documentation? Not exactly. VLC has a concat demuxer but it might not support inpoint/outpoint. Alternatively, we can use the `subsdelay` and `concat` access modules? This might be too complex. ### Practical Approach for the User: Given the complexity, and since the user already has hourly files, the simplest solution is to generate a playlist that contains all the hourly files in order and rely on VLC to play them consecutively. Then, the transition between hours will be seamless (if the setting is enabled). However, the program boundaries might not align with the hour boundaries, so there might be a small jump at the hour mark. But note: the user's playlist example already has consecutive hourly files. So why isn't VLC playing them consecutively? The user says: "на всеки час трябва да мина на следващ ако не съм включил на vlc следващо". This implies that the "Continue playback" setting is not enabled. So Step 1: Enable "Continue playback" in VLC. If the user wants a more sophisticated solution that respects program boundaries, then we must generate a playlist that uses the EPG to split the hourly files at the program boundaries. ### How to generate such a playlist? We need: 1. An EPG source (XMLTV file, for example) for the channel and date. 2. A script that: - Parses the EPG and for each program, determines the start and end time. - For each program, finds the hourly recording files that cover the program's duration. - For each segment of the program (if it spans multiple files), create a playlist entry with the appropriate start and stop time within the file. - But note: we cannot set an outpoint for the first segment and an inpoint for the next? Actually, we can, but then we have two separate entries. The playback would have a gap? Not if we set the start time of the next segment exactly at the end of the previous? But VLC will play them consecutively without gap if they are in the playlist. However, the transition between two segments of the same program might not be seamless? It might have a small gap. Alternatively, we can use the `concat` demuxer as described above, but we need to create a concat file per program. Then the playlist would have one entry per program, and that entry would be the concat file. But note: the user has a server that records hourly. We don't want to pre-process the files, just generate a playlist. ### Proposed Script for Generating the Playlist: We can write a script (in Python, for example) that: 1. Reads the EPG for the desired day and channel. 2. For each program in the EPG: - Calculate the start and end time. - Break the program into segments that fall into the hourly files. - For each segment, create a playlist entry with: - The file path for the hourly file. - The start time within that file (if the program starts after the beginning of the hour). - The stop time within that file (if the program ends before the end of the hour). - Alternatively, if we can use the concat method, generate a concat file for the entire program and then put that concat file as one entry in the playlist. But generating a concat file for every program might be messy. ### Using Inpoint and Outpoint in VLC: VLC supports the following in the M3U entry: ``` #EXTVLCOPT:start-time=15 #EXTVLCOPT:stop-time=30 http://example.com/file.mpg ``` But note: the `stop-time` will stop the playback at 30 seconds? Actually, the times are in seconds. So 15 minutes would be 900 seconds. Also, when the stop time is reached, VLC will stop and move to the next item. So if a program spans two files, we can do: Entry 1: ``` #EXTINF: ... #EXTVLCOPT:start-time=900 # 15 minutes in seconds #EXTVLCOPT:stop-time=3600 # end of the first file (at 60 minutes, but note the file is one hour so 3600 seconds) http://server/20250205-00.mpg ``` Entry 2: ``` #EXTINF: ... #EXTVLCOPT:start-time=0 #EXTVLCOPT:stop-time=1800 # 30 minutes into the second file (01:30 is 90 minutes from start of day, but the file starts at 01:00, so 30 minutes in) http://server/20250205-01.mpg ``` But the issue is that the two entries are for the same program? How do we name them? We want to have the same program name for both? Actually, the playlist would show two separate entries? That might be confusing. Alternatively, we can use a single playlist entry that spans two files? Not possible. ### Conclusion: Given the complexity, and if the user doesn't mind the hour boundaries, the best solution is to: 1. Enable "Continue playback" in VLC for the playlist of consecutive hourly files. If the user requires program boundaries, then: 2. Generate a playlist that uses the EPG to create entries for each program, and split the program if it spans two files. Each segment will be a playlist item with the correct start and stop times. The playlist will then be a sequence of these segments. The downside is that one program might appear as two or more items in the playlist, but they will be played consecutively. ### How to Generate the Playlist: We'll write a script that: - Takes an EPG in XMLTV format. - Takes a date and channel. - For that channel and date, for each program: - Determine the start and end time. - Generate a list of segments (file, start_relative, end_relative) for the program. - For each segment, output a playlist entry with: `#EXTINF:{duration}, {program_title} (Part {part_number}?)` `#EXTVLCOPT:start-time={start_in_seconds}` `#EXTVLCOPT:stop-time={end_in_seconds}` `http://path/to/hourly/file.mpg` But note: the `#EXTINF` duration should be in seconds? Yes, and it should be `end_in_seconds - start_in_seconds`. Example for a program that starts at 00:15 and ends at 01:30: Segment 1 (in 00.mpg): - start_in_seconds = 15 * 60 = 900 - end_in_seconds = 60 * 60 = 3600 - duration = 3600 - 900 = 2700 seconds Segment 2 (in 01.mpg): - start_in_seconds = 0 - end_in_seconds = 30 * 60 = 1800 - duration = 1800 seconds Playlist entries: ``` #EXTINF:2700, Program Title Part 1 #EXTVLCOPT:start-time=900 #EXTVLCOPT:stop-time=3600 http://xxx.xxx.xxx.xx/archive/1994/20250205-00.mpg #EXTINF:1800, Program Title Part 2 #EXTVLCOPT:start-time=0 #EXTVLCOPT:stop-time=1800 http://xxx.xxx.xxx.xx/archive/1994/20250205-01.mpg ``` But the user might not want to see "Part 1", "Part 2". We can omit that and just use the same title? Then it will show two entries with the same title? That might be acceptable. Alternatively, we can use a single entry with the entire program by using a concat file? But then we have to create a concat file on the fly and serve it? That might be more complex. ### Implementation of the Script: We'll assume the recordings are stored by a fixed pattern: `{date}-{hour}.mpg` in a directory. The date format is "YYYYMMDD", and the hour is two-digit hour (00, 01, ...23). Steps: 1. Parse the EPG (XMLTV) for the given channel and date. 2. For each program in the EPG that starts on that date: - Let `prog_start` and `prog_end` be the start and end times (as UNIX timestamps or datetime objects). - Calculate the duration of the program in seconds: `prog_duration = (prog_end - prog_start).total_seconds()` - Find the hourly files that overlap with the program. - For each overlapping hour file (from `start_hour` to `end_hour`): - Let `file_start` be the start time of the hour file (as a datetime). - Let `file_end` = `file_start + timedelta(hours=1)` - The segment start within the file: - If the program starts after the file start, then `segment_start = (prog_start - file_start).total_seconds()` - Else, 0. - The segment end within the file: - If the program ends before the file end, then `segment_end = (prog_end - file_start).total_seconds()` - Else, 3600 (one hour). - Append a playlist entry for this segment. 3. Write the playlist. ### Example Code (Python Pseudocode): ```python import xml.etree.ElementTree as ET from datetime import datetime, timedelta import os # Configuration epg_file = "epg.xml" recordings_base_url = "http://xxx.xxx.xxx.xx/archive/1994/" recordings_date = datetime(2025, 2, 5) # The date of the recordings channel_id = "Eurosport" # The channel id in the EPG # Parse EPG tree = ET.parse(epg_file) root = tree.getroot() # Convert recordings_date to the string format used in the filenames: YYYYMMDD date_str = recordings_date.strftime("%Y%m%d") # Find all programs for the channel and date # Note: EPG times are usually in UTC and formatted as strings, e.g., "20250205000000 +0000" # We'll assume the EPG uses local time and adjust accordingly. # We'll collect programs in a list programs = [] for programme in root.findall(".//programme"): # Example: chan = programme.get("channel") if chan != channel_id: continue start_str = programme.get("start") stop_str = programme.get("stop") # Parse the time string: format is usually YYYYMMDDHHMMSS [timezone] # We'll parse without timezone for simplicity (assuming local time) start_time = datetime.strptime(start_str[:14], "%Y%m%d%H%M%S") end_time = datetime.strptime(stop_str[:14], "%Y%m%d%H%M%S") # Check if the program is on the desired date if start_time.date() != recordings_date.date(): continue title_elem = programme.find("title") title = title_elem.text if title_elem is not None else "Unknown" programs.append((start_time, end_time, title)) # Sort programs by start_time programs.sort(key=lambda x: x[0]) # Generate the playlist playlist = "#EXTM3U\n" for start_time, end_time, title in programs: # Break the program into hourly segments current_segment_start = start_time while current_segment_start < end_time: # The hour file that covers current_segment_start hour = current_segment_start.hour file_start = datetime(current_segment_start.year, current_segment_start.month, current_segment_start.day, hour, 0, 0) file_end = file_start + timedelta(hours=1) segment_start_in_file = (current_segment_start - file_start).total_seconds() segment_end_in_file = min((end_time - file_start).total_seconds(), 3600.0) # The duration of this segment segment_duration = segment_end_in_file - segment_start_in_file # Generate the filename for this hour filename = f"{date_str}-{hour:02d}.mpg" url = recordings_base_url + filename # Add to playlist playlist += f"#EXTINF:{int(segment_duration)},{title}\n" playlist += f"#EXTVLCOPT:start-time={segment_start_in_file}\n" playlist += f"#EXTVLCOPT:stop-time={segment_end_in_file}\n" playlist += url + "\n" # Move to next segment (if any) current_segment_start = file_end if current_segment_start >= end_time: break # Save the playlist with open("dynamic_playlist.m3u", "w") as f: f.write(playlist) ``` ### Notes: - This script generates a playlist that plays each segment of each program in order. - The `#EXTVLCOPT` directives are used to play only the part of the file corresponding to the program segment. - The `#EXTINF` duration is set to the segment duration so that VLC shows the correct remaining time. ### How to Use: 1. The user must have an EPG file for the day and channel. 2. Run the script to generate the playlist for that day. 3. Open the generated playlist in VLC. ### Caveats: - The EPG times must be accurate and in the same timezone as the recordings. - The script doesn't handle programs that span midnight (if the recordings are for one day only). ### Conclusion: This solution provides a playlist that respects program boundaries by splitting the hourly files into segments. The playlist will be longer (with multiple entries per program if it spans hours) but will play seamlessly if VLC is set to continue playback. If the user does not require program boundaries and just wants consecutive playback of the hourly files, then the simple solution is to enable "Continue playback" in VLC and use a playlist of the hourly files in order. От примерния плейлист виждам, че имате записани почасови .mpg файлове за конкретна дата (2025-02-05) с именуване във формат ГГГГММДД-ЧЧ.mpg. За да автоматизирате превключването между часовите файлове във VLC и да ги синхронизирате с EPG, ето решенията: 1. Автоматично преминаване между файлове във VLC (без EPG) Ако искате просто последователно възпроизвеждане без ръчно превключване: Активирайте настройката във VLC: Tools → Preferences → Show Settings: All → Playlist ✓ Continue playback След това рестартирайте VLC. Създайте плейлист с всички файлове за деня: m3u #EXTM3U http://xxx.xxx.xxx.xx/archive/1994/20250205-00.mpg http://xxx.xxx.xxx.xx/archive/1994/20250205-01.mpg http://xxx.xxx.xxx.xx/archive/1994/20250205-02.mpg ... (добавете всички файлове за деня) VLC автоматично ще преминава към следващия файл. 2. Синхронизация с EPG (автоматично превключване според програмата) За превключване точно в началото на всяко предаване според EPG: Необходими стъпки: EPG източник: Вземете EPG данни за канала във формат XMLTV (напр. от epg.bg или чрез xmltv инструменти). Скрипт за генериране на динамичен плейлист: Скрипт на Python, който: Чете EPG файла (epg.xml) Създава плейлист със записи, групирани по предавания (вместо по часове) Използва #EXTVLCOPT за задаване на начално време за всяко предаване. Примерен код (generate_playlist.py): python import xml.etree.ElementTree as ET from datetime import datetime # Конфигурация EPG_FILE = "epg.xml" BASE_URL = "http://xxx.xxx.xxx.xx/archive/1994/" OUTPUT_PLAYLIST = "eurosport_epg.m3u" # Зареди EPG данни tree = ET.parse(EPG_FILE) root = tree.getroot() # Генерирай плейлист with open(OUTPUT_PLAYLIST, "w") as f: f.write("#EXTM3U\n") for program in root.findall(".//programme"): # Пример: start_time = datetime.strptime(program.get("start")[:12], "%Y%m%d%H%M") hour_str = start_time.strftime("%H") file_date = start_time.strftime("%Y%m%d") # URL на записа за съответния час file_url = f"{BASE_URL}{file_date}-{hour_str}.mpg" # Начален секунди във файла (ако предаването не започва в началото на часа) start_seconds = (start_time.minute * 60) + start_time.second # Запиши в плейлист title = program.find("title").text if program.find("title") is not None else "Без заглавие" f.write(f"#EXTINF:-1, {title}\n") f.write(f"#EXTVLCOPT:start-time={start_seconds}\n") f.write(f"{file_url}\n\n") Как да използвате: Вземете EPG файл за канала (напр. epg.xml). Пуснете скрипта: bash python3 generate_playlist.py Отворете генерирания eurosport_epg.m3u във VLC. VLC ще превключва автоматично към следващото предаване, като използва началните времена от EPG. 3. Автоматично обновяване (cron + скрипт) За да обновявате плейлиста автоматично преди всяко предаване: Създайте cron задача, която пуска скрипта на всеки 30 минути: bash */30 * * * * /usr/bin/python3 /path/to/generate_playlist.py Във VLC отворете eurosport_epg.m3u като "Мрежов поток" (Ctrl+N) с адрес: http://вашият_сървър/eurosport_epg.m3u (ако плейлистът е достъпен през уеб). Важни бележки: Именуване на файлове: Скриптът очаква файлове във формат ГГГГММДД-ЧЧ.mpg (напр. 20250205-01.mpg). EPG синхронизация: Ако предаването трае повече от 1 час, ще трябва да комбинирате няколко файла (скриптът поддържа само 1 файл на предаване). За сложни сценарии използвайте TVHeadend или NextPVR. Тестване: Проверете дали VLC версията ви поддържа #EXTVLCOPT:start-time. Ако имате нужда от помощ с EPG източник или адаптация на скрипта, моля, уточнете!
