ffmpeg doesn't work when the script is launched by cron - No protocol specified, Cannot open display :0.0
14 janvier 2024, par a kffmpeg in my script doesn't work when the script is launched by cron of the root


Error : No protocol specified, Cannot open display :0.0


OS : Ubuntu 20.04

When Cron (Cron of the root) launches the script, ffmpeg shows the error "No protocol specified, Cannot open display :0.0"


/var/log/log2/log2.txt :

When I launch the script manually as a not-root user (with sudo), everything work correctly :

When I launch the script manually as the root, everything works correctly :

drwxrwxrwx 2 root root 4096 mai 5 04:11 log2

When crontab of an ordinary user launches the script, it works correctly :


$DISPLAY =

whereis ffmpeg ffmpeg: /usr/bin/ffmpeg /usr/share/ffmpeg /usr/share/man/man1/ffmpeg.1.gz

ls -l /var/log | grep log2 
drwxrwxrwx 2 root root 4096 mai 5 05:05 log2
pid ffmpeg $! = 77601
exit



I have tried to put into the script :

Python Discord music bot stops playing a couple of minutes into any song
9 mars 2023, par knewbyI am trying to put together a Python Discord music bot as a fun little project. Outside of the required discord library I'm currently using the YouTube API to search for videos and parse the URL (not shown in code), yt-dlp which is a fork of yt_download that is still maintained to get the info from the YT URL, and FFMPEG to play the song obtained from yt-dlp through the bot. My play command seems to work as the 1st YT video result will start to play, but roughly 30-90 seconds into the audio, it stops playing. I get this message in the console :


2023-02-23 14:54:44 IN discord.player ffmpeg process 4848 successfully terminated with return code of 0.


So there is no error for me to go off of. I've included the full output from the console below...


-----------------------------------
groovy-jr#6741 is up and running
-----------------------------------
2023-02-23 14:53:23 INFO discord.voice_client Connecting to voice...
2023-02-23 14:53:23 INFO discord.voice_client Starting voice handshake... (connection attempt 1)
2023-02-23 14:53:24 INFO discord.voice_client Voice handshake complete. Endpoint found us-south1655.discord.media
2023-02-23 14:54:44 INFO discord.player ffmpeg process 4848 successfully terminated with return code of 0. <= AUDIO STOPS



I'm currently developing this project on a Windows 11 machine, but I've had the issue running it on my Ubuntu machine as well. I am just hosting the bot directly from the VSCode terminal for development.


I've been trying to do research on this problem, the problem is I can't find many recent information for the issue. There was another post that talked about a similar problem and had an answer suggesting the following FFMPEG options be used which I tried to no avail.


FFMPEG_OPTIONS = {
 'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5',
 'options': '-vn',
 }



I'll include the problem file below :

I appreciate any guidance I can get !

`ffmpeg -f concat` don't work when all input streams appear to have the same spec
2 octobre 2024, par RoyMy
ffmpeg

ffmpeg -safe 0 -f concat -i list.txt -c copy out.mp4

The above command outputs some warning signals :


[mov,mp4,m4a,3gp,3g2,mj2 @ 0000025239902d40] Auto-inserting h264_mp4toannexb bitstream filter
[mp4 @ 00000252396fe5c0] Non-monotonous DTS in output stream 0:1; previous: 218112, current: 150024; changing to 218113. This may result in incorrect timestamps in the output file.
...
a lot of them

video:9649kB audio:1519216kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown



The resultant video can play the first part of the video correctly, then the video players either skips directly to the end of the video (MPC-HC), or don't render anything at all while timer passes as normal (VLC).


My impression of the concat is that it requires all videos to have the same spec, which I think my input achieved (all the "Steam #0:0", etc, line matches). I only see the following difference, which I assumed that should be okay :


- 

- Metadata are different both for the whole input (e.g. "major_brand") and for each stream (e.g. "encoder"). I assumed that metadata won't affect the processing.
- The order of video/audio streams are different in the two inputs : the 1st input file has audio then video ; the 2nd input file has video then audio. I assumed that ffmpeg knows the difference and won't concat a video stream to an audio stream.
