Yes, quite possibly.

>> The second file - patent-absurdity_288p30.y4m_vp9-256kbps_opus-32kbps.webm - contains a VP9 video track, and an Opus audio track.  VLC (both 2.1.4, and the latest "git") is almost able to play the video track (video show up, but is mostly artifacts/garbage).  The Opus audio track doesn't play at all in 2.1.4, but does play OK in the latest "git" version.
> git version play it flawlessly.

Not for me on Mac OS X.  The latest git version ("Version 2.2.0-git Weatherwax (Intel 64bit)") built/run on Mac OS X doesn't play it (without mostly artifacts/garbage).  So, the problem might be platform-specific?
