This format is named as X2R10G10B10 in libva, but I think X2RGB10 is more
concise. There is similar format name defined in Gstreamer like RGB10A2.
Because there are lots of Codec/Filter based on third-party library in ffmpeg, while
in these library they may support some specific format like P010/Y210/Y410.., so in
Ffmpeg side it should support this kinds of formats first, at least the definition.
