Can we merge the vpp scale/the other vpp filters in one AVFilter, e,g
vf_postprocess_vaapi.c.
If we split the scale/the other vpp filters, I guess maybe have some
performance issue,
when merge the scale/the other vpp filters in one AVFilter, only once surface
copy ,
1 input surface-> 1 output surface // once copy for
scale/de-noise/sharpness/...
but if split them, it's will lead to twice surface copy in some case.
1 input surface -> 1 output surface -> 2 output surface // 1st copy for
scale, 2nd
// copy for the
other vaapi filters
Anyway, need to more test for this.

I think i965 driver guys will fix this issue:)
