7b41785eb6 fftools/ffmpeg: replace stream timebase with decoded frame one 
They are the same for now, but this may change in the future.

1372e81aaa fftools/ffmpeg: drop a useless local variable 
Store decoded frame timestamp directly in AVFrame.pts, there is no
advantage to using a separate local variable for it.

94a9647195 fftools/ffmpeg: shorten a variable name 
There is only one frame used in decode_video() -- the one output by the
decoder. So there is no point in explicitly calling it the _decoded_
frame.

c37cf59c5b avfilter/vf_xfade: send EOF to first input early

21715ecff1 lavfi/vf_libplacebo: update peak detection options 
Upstream peak detection lost one option and gained one option. Update

643cf2ec46 lavfi/vf_libplacebo: update for new tone mapping API 
This algorithm has once again been refactored, this time leading to a
dropping of the old `tone_mapping_mode` field, to be replaced by a
single tunable hybrid mode with configurable strength.

We can approximately map the old modes onto the new API for backwards
compatibility. Replace deprecated enums by their integer equivalents to
safely preserve this API until the next bump.

d637f20f05 lavfi/vf_libplacebo: switch to new gamut mapping API 
Upstream deprecated the old ad-hoc, enum/intent-based gamut mapping API
and added a new API based on colorimetrically accurate gamut mapping
functions.

The relevant change for us is the addition of several new modes, as well
as deprecation of the old options. Update the documentation accordingly.

f66280182a lavfi/vf_libplacebo: add RGB colorspace sanity 
Explicitly forbid using a non-RGB colorspace with RGB pixel format or
vice versa. This mirrors identical logic from vf_scale.

c00fd02558 lavfi/libplacebo: properly handle EOF 
The current code relied on pl_queue eventually returning EOF back to the
caller, which didn't work in all situations (e.g. single frame input).
Also, the current code assumed that ff_inlink_acknowledge_status only
fired once, which was patently not true, as the above edge cases
demonstrated.

Solve both issues by keeping track of the acknowledged link status and
forwarding it (instead of trying to probe the pl_queue again) in the
event that we run out of queued input frames, as well as (in CFR mode)
when we pass the indicated status PTS.
