What do these formats describe? Are these container formats or the actual
compressed video stream that is normally packaged inside a container?

??? Weird CODEC_BASE offsets?
Are all these codec controls above general? I.e., applicable to any codec? What
do they mean?

It's probably a good idea to only add this BASE define to videodev2.h
(please include a comment describing the control range reserved for the MFC51).
All others should go to a public mfc51 header. Which should include
documentation
for these controls as well.
