Mkv (and av1, vp8, vp9) use the leb128 format which the article mentions is inefficient parse for off the shelf CPUs.

Leb128 is relatively efficient in bitstream and sidesteps potential mpeg-la patent issues. (H264, maybe 14496 part 14)

I don't think they do. These formats are based on EBML, see the RFC link in my previous comment. That VINT encoding is not LEB128, it's better.

BTW I once implemented my own parser in C#, see that source file: https://github.com/Const-me/Vrmac/blob/master/VrmacVideo/Con...
