Comment (by pulkomandy):
So, this is not related to mkv (which is only a container) but to the
format used inside it.
In the case of the attached video this is h264 using the "high 10"
profile, which is decoded with a pixel format of yuv420p10le. This means:
* It is an YUV format
* There are 4 Y samples for one U and V (in a 2x2 grid)
* It is planar: all Y data comes first, followed by U, then V
* Each sample is stored on 10 bits (but it seems this is padded to
16-bits?)
* The bytes are in little endian order

There is not (yet) a colorspace in Haiku matching this, and there is also
not yet a converter to RGB32.
