Why am I suspicious that at least one of those is a re-ordered v210?  I
seem to recall that we rejected adding v210 to this list.  Either they
don't belong in this list or they don't belong because libavcodec has a
proper decoder (at least for v210).

No real conclusion was reached there.

Do bit-packed formats belong in an AVPixelFormat?
