There were comments on the "libi264" naming (Carl Eugen and Hendrik Leppkes, at
least), and I agree with them.  This would make more sense if it used the
"libva" or "vaapi" naming conventions and existing config flags.  Ideally there
is nothing Intel-speciic about the implementation itself, even if you are using
it with the Intel driver.

It would be nice if the naming also left open the possibility of adding support
for other codecs using this same interface in the future.  The QSV codec, for
example, uses a naming scheme where the API comes first, followed by the
specific codec (h264 or hevc).  So something like "vaapi_h264" would work well
