matroska: add support for header stripping with no lacing
ivf: make sure to not read outside of the codec private data
Multimedia container file system.
Someday this might end up as a 9p filesystem for various video container formats so other programs (vidya players) can identify formats and extract streams properly.
extra/ contains additional tools:
video/mkvdump, to dump MKV in human readable formand.
video/ivf2raw, to rip raw video frames out of IVF.
The code looks horrible(?).
It's not a filesystem yet, but it can extract video streams (as IVF) and audio streams from MP4 and MKV.
