• ffmpeg encoding .mp4 fails in safari when hosted from s3. handbrake encoded video works first time

  11 juin 2018, par Simon Rogers

  The mp4 videos I’ve encoded with ffmpeg work perfectly in Safari if stored locally, but break if hosted from s3. I have tried countless encoding settings to no avail.

  However having just run a mov quickly through Handbrake and ticking ’optimise for web’ and encoding baseline @ 4.0, this has worked perfectly first time.

  I don’t understand what could be going wrong with my ffmpeg encoding.

  Things I have noticed about files from two separate encoders which work :

  They both have yuv420p(tv, bt709) whereas ffmpeg is just saying yuv420p – this is the only thing I can identify from ffprobe that is consistently different.

  I have done a fresh install of ffmpeg to no avail :

  ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

  brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-libass  --with-libvorbis --with-libvpx --with-opus --with-x265

  This error appears in all the files I have encoded with ffmpeg :

  Unsupported codec with id 0 for input stream 1

  mp4box gives the following for the ffmpeg video, which doesn’t work :
