• ffmpeg - Convert mkv to mp4 on ubuntu 18.10 error ?

  28 mars 2020, par ScipioAfricanus

  I am trying to convert some mkvs to mp4s on Ubuntu 18.10 with ffmpeg, and I keep getting the error below. Aby thoughts ?

  I am following https://linuxconfig.org/install-ffmpeg-on-ubuntu-18-04-bionic-beaver-linux#h2-operating-system-and-software-versions

  I have installed ffmpeg and installed :

  sudo apt install -y libopus-dev libmp3lame-dev libfdk-aac-dev libvpx-dev libx264-dev yasm libass-dev libtheora-dev libvorbis-dev mercurial cmake

  Command I ran with output :

  ffmpeg -i 'video.mkv' -codec copy 'video.mp4' -strict -2 -y

• ffmpeg encoded hls makes audio and video progressively out of sync

  21 septembre 2020, par eschie

  When trying to encoding a source .mp4 to multiple bitrates and sizes for adaptive HLSv3 playback the resulting audio and video become progressively out of sync. When scrubbing to a later point it seems to reset, and stay in sync.

  



  I'm on the latest ffmpeg 4.2.1 via homebrew-ffmpeg, with the libfdk-aac codec. Note, this was also occurring with ffmpeg 4.1.

  The audio and video streams are marginally off, would that cause this problem ?
