• Muxing together a .ts file and a sub file causes playback issues in video and audio [closed]

  3 mai 2024, par Meta83

  So I have a .ts file and a converted .dvb sub file (.SRT TO .DVB) that I want to mux togheter using FFMPEG. The mux is a success and the file plays fine in VLC or other modern divce.However I have an older divce (around 10 yeras old) where playback has issues, whenever a line of subs is displayd the picture and and audio gets corrupted and frezzes up and as sson there are no lins everything looks good again and so on. Note that subs are displayd correctly and they are not affected by the issue, only picture and audio is.

  


  I have tried using diffrent command without any luck but here is the most basic command that should work :

  


  ffmpeg -i <video file="file"> -i <dvb file="file"> -f mpegts -c:v copy -c:a copy -c:s copy -copyts <output file="file">&#xA;</output></dvb></video>

  


  Here is the output I get frome FFMPEG :

• How to set min, max and avg bitrate or vbv delay using FFMPEG for livestream in Python ? [closed]

  10 mai 2024, par Tebyy

  I'm trying to set the minimum, maximum, and average bitrate or vbv delay for a WebM livestream in Python using FFMPEG, but it still shows "0" or "N/A". I've checked the documentation, and everything seems correct. I've also searched for solutions online, but none of them have solved my problem. Does anyone know what I might be doing wrong and how it should be done correctly ?

  ffmpeg_command = [
        'ffmpeg', '-f', 'rawvideo', '-pix_fmt', 'bgr24',
        '-s:v', '1920x1080', '-r', '60',

• Moviepy not updating FFmpeg Version after FFmpeg Install ?

  31 mai 2024, par The_ Game12

  I've been toying around with MoviePy, and recently switched a project to a new computer at home to continue messing around with it. However, I tried running what I had previously written (which ran perfectly fine on the other computer) and I get this :

  


  OSError: MoviePy error: failed to read the first frame of video file ./Gameplay/minecraft-
gameplay2.mp4. That might mean that the file is corrupted. That may also mean that you are using 
a deprecated version of FFMPEG. On Ubuntu/Debian for instance the version in the repos is 
deprecated. Please update to a recent version from the website.



  


  After reading the error, I did as it instructed, and updated my FFmpeg :

  


  $ ffmpeg

  And I continued getting the same error. So I looked at what version my moviepy was using, and it was still 4.X. I read somewhere that your FFmpeg version is determined on the first use, which made sense, so I uninstalled and reinstalled, to get the same error.

  


  I am honestly lost at this point, as I have the newest version of FFmpeg, but I still get this from moviepy :

  


  >>> import moviepy&#xA;>>> print(moviepy.config.FFPMEG_BINARY)&#xA;ffmpeg : /home/<username>/.local/lib/python3.9/site-packages/imageio_ffmpeg/binaries/ffmpeg-linux64-v4.2.2&#xA;</username>

  


  Any Ideas as to what I'm doing wrong ?

  


  (Note : I'm using Crostini which I believe is using an Ubuntu or Ubuntu-Like shell)

  


  Thanks :)
