Maybe not yet - Been testing cbr and vbr and these seem OK still.

There is an issue with cqp that I'll have to test further - it could be related
to the source size, I am not sure yet.

With 2160p gstreamer is Ok with its default QP of 26 or 28, but any higher it
bails with -

gstvaapiencode.c:210:gst_vaapiencode_default_alloc_buffer: invalid
GstVaapiCodedBuffer size (0 bytes)

gstvaapiencode.c:316:gst_vaapiencode_push_frame: failed to allocate encoded
buffer in system memory

It may be that there are other ways to hit this before the patches - I'll try
more tomorrow.
