* avcodec/vaapi: increase av1 decode pool sizeFei Wang2021-10-16

* avcodec/hevcdec: apply H.274 film grainNiklas Haas2021-10-15
| | | | | | | | | | | | | | | | Similar in spirit and design to 66845cffc3bbb, but slightly simpler due to the lack of interlaced frames in HEVC. See that commit for more details. For the seed value, since no specification for this appears to exist, I semi-arbitrarily decided to base it off the POC id alone, since there's no analog of the idr_pic_id in HEVC's I-frames. This design is stable across remuxes and seeks, but changes for adjacent frames with a period that's typically long enough not to be noticeable, which makes it satisfy all of the requirements that a film grain seed should have. Tested with and without threading, using a patch to insert film grain metadata artificially (for lack of real files containing film grain).
