• Correct usage of fdkaac for liquidsoap->icecast

  1er février 2024, par user4893295

  Can't seem to get aac working using fdkaac with liquidsoap. It just seems to shutdown.

  


  TBF I have no idea which aot or transmux to use for "normal" icecast stuff. mp3 works fine, and the icecast server works fine with aac from other sources (BUTT etc).

  


  This is my starting point from the liquidsoap cookbook :

  


  %fdkaac(channels=2, samplerate=44100, bandwidth="auto", bitrate=64, afterburner=false, aot="mpeg2_he_aac_v2", transmux="adts", sbr_mode=false)


  


  And this is my output from liquidsoap :

  But no idea why or how to stop that...

  


• washed out colors when converting h264 into vp9 using ffmpeg [closed]

  31 juillet 2024, par apes-together-strong

  I'm trying to convert an h264 video to vp9/opus webm.
Every attempt so far has had washed out colors.
Is there a fix for this issue or is it just the way h264->vp9 conversion is ?

• Yet another ffmpeg concat audio sync issue [closed]

  15 mars 2024, par Demiurg

  I've read through dozens of posts, tried many suggestions, nothing seems to work for me. The funny part is that the video is fine in some players (e.g. Quicktime) but not the others (e.g. Chrome).

  


  This is what I currently use :

  


  ffmpeg -i segment.mp4 -q 0 -c copy segment.ts
ffmpeg -f concat -i videos.txt -c copy -y final.mp4


  


  This is what ffmpeg shows for the originals
