Output:
Filter overlay
Overlay a video source on top of the input.

Inputs:

Hi, still waiting for this to get merged.
I'm happy to make any changes if you still find something off.
Paul, I CC'd you since you've done function changes to this file in 2012.
Note that this is a prerequisite for a larger decoder patch:

Allow user to disable codec probing:
- spdif (and s337m incl. s-adm in the future) is not sub-demuxed and
may pass-through to a muxer
- disable any stream probing in wav files (dts detection).
- mpeg-ts files missing PAT/PMT are considered invalid.

bit_rate is not a critical field, and we shouln't hard fail if we
can't caluclate it due to a large timebase - it needlessly breaks
valid files.

Did we reach a consensus on this? While I think signalling ffmpeg
VAAPI needs 2 output surface for film grain frame. One used for
reference and the other used for applying film grain and pushing
to downstream.

For film grain clip, vaapi_av1 decoder will cache additional 8
surfaces that will be used to store frames which apply film grain.
So increase the pool size by plus 8 to avoid leak of surface.
