Does MP4 support VP9 codec or is it exclusive to WebM?

1

ffmpeg v4.0.2 or higher can encode/transcode VP9 in mp4.

Commandline (when encoding): ffmpeg -i INPUT.MKV -c:v vp9 OUTPUT.MP4

Commandline (when transcoding (Super fast)): ffmpeg -i INPUT.MKV -c:v copy OUTPUT.MP4

FFmpeg, a command-line app, can write VP9 streams in MP4s.

Get a static daily/snapshot binary from https://ffmpeg.zeranoe.com/builds/

Basic command is

ffmpeg -i in.mov -c:v vp9 out.mov

  • Works here. You got the 20170317 static build, right? Use full form: -c:v libvpx-vp9 – Gyan Mar 20 '17 at 12:41
