ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at gmail.com> | Wed Feb 17 01:12:41 2021 +0100| [1406b3cc23e3a9556bab5633f37e2a27e7794331] | committer: Andreas Rheinhardt

fate/matroska: Add test for remuxing VP8 with alpha

This provides coverage for writing BlockGroups with BlockAdditional
and ReferenceBlock elements. It also tests setting the hearing impaired
disposition (it fits given that this video has no audio so one needs to
be able to read lips to understand anything).
