[Cin] Fwd: two more h264_vaapi profile for cingg

[Phyllis Smith]

Checked these 2 into GIT after testing.  About the following:

Instead "h264_vaapi.mkv" gives me error and no rendering.

I added a message to the format to state that the mkv "only works on
computer that has vaapi capable software and hardware".  I got the same
error message as Andrew on my AMD laptop that does not handle vaapi, but an
old HP laptop has it working.  Not exactly sure that is the correct reason
but it is all I could think of.  Correct me if I am wrong.
