• FFMPEG wrong duration when using amix filter

  12 mars 2020, par Leonard

  I am trying to add background music to a video with an existing audio-track. I settled for the amix filter, since other filters seemed to cause a delayed audio track. So far everything is working as intended, however the output video is cut off at 11:34min. Which is 3 seconds shorter than the input video. I already tried to increase the length of the input video by e.g. 5 seconds, which still leads to the same output length of 11:34min. Here is the exact command I am using :

  ffmpeg -i video.mp4 -i bg_music.wav -filter_complex "[0:a]volume=1.5[a0];[1:a]volume=0.2[a1];[a0][a1]amix=duration=shortest[a]" -map 0:v -map [a] -c:v copy -c:a aac -ar 22050 out.mp4

  And this is the output I am getting. In this call the video has a length of 11:42min and the audio a length of 36:59min. I am running macOS Catalina 10.15.3 :

• Error compiling FFMPEG / libav code after adding avfilter

  9 mai 2020, par Daniel Kobe

  My encoding and decoding was working fine using ffmpeg and libav, but then I added a filter in the encoding step to rotate my video and it no longer works in my docker machine, BUT it does work locally.

  



  The error message when compiling in docker is

  How can I get my configuration fixed so it works like in local ? I didn't specifically configure my local environment so it's going to be using default configuration.
