Lots of crashes, from only a few installs.

FFmpegVideoDecoder is calling into ClaimSnapshotGLContext() is calling into GLLibraryEGL::fInitialize() is calling into a graphics driver. Maybe it isn't okay to call into this driver code from the media decoder thread?

Yeah, these are all from one graphics card and one particular distro, so I think it is one person who is crashing a lot.

Comes from VA-API playback. But it's AMD device where VA-API is disabled by default so it's user pref.
