Thanks for your comments.
I'll use MFX_RESOURCE_SYSTEM_SURFACE and send another patch.
While implementing this feature, I noticed that
vpp_set_frame_ext_params is called multiple times.
If using system memory for storing 3D LUT, is it possible the LUT
table copying to gfx memory will occur
Thanks for reviewing this patch.
Do you mean this should be merged with the change to vf_vpp_qsv file
and send only one patch file?

The spec allows at least thirty-two zero bits followed by a one to mean

There is never an alpha component here, so the actual format is BGR0
rather than BGRA. This fixes cases which maintain the alpha component
and therefore generate unexpected results.

E.g. fixes download and encode with PNG to make an RGB PNG as expected, rather
than an RGBA PNG with nothing
The 8-bit four-component DXGI container is also used for three-component
RGB without alpha.

This list is only used for AV->DXGI mapping, so it doesn't matter that there
are duplicate DXGI formats in the list.

Revealed by the patch to support animated webp, the current
frame threading implementation contains a data race.
vp8_lossy_decode_frame() calls ff_vp8_decode_frame() wich
calls ff_thread_finish_setup() to sync its internal slice threading.
The race is happens because vp8_lossy_decode_frame() has
