• How to union RAW video data stream with RAW data audio stream through ffmpeg .net

  17 septembre 2022, par zabitstack

  I'm trying to union a raw video data stream with raw audio data stream but without success ! I capture video from webcam and audio from microphone in .net Accord Framework application.

  


  I want use ffmpeg core .net library to transform raw video data into a avi file, then same thing transform raw audio data into mp3 format file. Next merge mp3 with avi in single avi video+audio file.

  


  If you want, I can post source code how I capture data.

  


• Video conversion (using ffmpeg) fails only on apache server

  25 avril 2022, par wb.waldemar

  I'm trying to convert a video using latest static build of ffmpeg and following command :

  


  ffmpeg -report -y -loglevel info -i en--story-video.mp4 -c:v libx264 -preset slow -crf 22 -c:a copy en--story-video-out.mp4


  


  This works actually fine on Ubuntu (desktop) and the same command works also on Win 10 but not on the server (Debian GNU/Linux 10) where it should actually work. I can't install or build ffmpeg directly so I've to use a static build. Also simple remux works on the server but not the converion and I do not understand why. I've also read and tried different approaches and suggestions, but none of them could solve the problem.

  


  Does someone have an idea what goes wrong ?
