Comment (by Peter Bennett):

 There are two issues I found with VAAPI2 so far.

 On an older computer, H265 is not supported with VAAPI and it was
 switching to software decoding but only using 1 CPU.

 On a newer but less powerful computer it is using VAAPI to decode but it
 is doing conversions and moving frames around in storage, causing the
 slowdown.

 I have a fix for the first and a partial fix for the second.
