VP9 playback broken?

Hi,

Was doing some test for another issue when I found this: today’s 64 bits nightly does not play VP9

If you try to launch a video file using VP9 video codec, Kodi will just play the audio track as if you tried to play a music file

Here is the log: https://pastebin.com/GYP4fx68

Just to be sure, I tried with a nightly I knew it was working (KodiSetup-20170512-ac10c3d3a7-master)

And as expected, VP9 playback works!

Here is the log: https://pastebin.com/QHhmEwD0

Looking at these logs, I saw that ffmpeg goes from 3.1 to 3.3

Could it be the culprit?

Any help appreciated…
