Upstream finally caved in to peer pressure and added this filter. Of
course, this also removes the fallback for people on older versions of
libplacebo, but people using mpv git master are probably using
libplacebo git master anyway. It's time to debloat this code.
Upstream has moved from passing struct pl_icc_profile to directly
attaching a managed pl_icc_object, plus providing a new function
pl_icc_update to update the ICC profile object parameters (if needed).
To facilitate this move, pull our ICC params back out of pl_options and
update the target ICC object directly.
Interrim solution, forwards compatible with new and backwards compatible
with old API. Eventually, we will want to discontinue the use of
deprecated pl_icc_params.save/load and pl_renderer_save/load, but that
requires minimum version bump.
Causes bad performance with interpolation because the changing hue angle
invalidates the mixing cache, as a result of libplacebo implementations
(specifically, the fact that this graph is drawn during the color
management process, instead of as a separate overlay).
Fix it by just hard-coding a particular, relatively interesting plane
(pi/4 approximately maps onto the red-blue axis).
Pick a smarter rect, limit it to right half of screen (to allow more
easily using it simultaneously with stats), and also auto-rotate through
the hue plane by default (wrapping once every 10 seconds of playback).
I briefly considered making it based on wallclock time instead of pts,
but this has the rather unfortunate downside of only being updated
sporadically as the user moves the mouse over OSC elements. (Of course,
we could also forcibly redraw the screen continously to avoid it, but
I'd rather not make such an invasive change for no real reason)
This design also allows you to pause and focus on (via framestepping)
individual parts of the hue graph that you're interested in.
This actually fixes a bug that was present in this code even before the
new pl_options system, which is that `video_screenshot` would
permanently leave `peak_detect_params.allow_delayed` as false, until
something else forced options re-application due to options cache
change.
Before d208284, this was implicitly reset back to 0 at the start of
every update_options(). But we no longer explicitly reset par->params,
so we need to do it manually here for the hooks.

With a backwards compatibility shim for older versions of libplacebo in
which we simply define the relevant subset of this struct ourselves and
initialize it to known-good values, to be able to continue using our
options assigning code.
It's worth pointing out that our use of scalers deviates from how
pl_options was intended to be used, as a consequence of backwards
compatibility with pre-308 versions of libplacebo. But this should work
fine in practice, since we don't care about serializing these custom
scalers correctly. Users can still override them using the built-in
pl_options scalers when loading custom scalers via --libplacebo-options.

This was already correctly freed when acquiring a new profile, but never
freed on uninit. Fix by reparenting the profile onto `p`, which is what
vo_gpu also does.
983e8f0100 resulted in the correct
dimensions, but it was not actually right because vo_gpu_next still had
the src and dst rects the same. This just needs to work like how vo_gpu
does where the src is the image params and the dst is desired output. So
basically, just copy that code over here. Fixes#12108 and as a bonus,
overriding the aspect ratio now results in correct screenshots
(previously didn't work at now and then with the above commit it had
correct dimensions but still incorrect output).
Using the width and height params directly doesn't actually work if PAR
is something other than 1. Instead, use mp_image_params_get_dsize and
calculate the correct dimensions which matches the vo_gpu behavior.
1 is not enough to prevent PL_QUEUE_MORE, because the pl_queue is
designed to always know the next frame (in addition to the current).
Before haasn/libplacebo@112bb886, this was was (wrongly) silently
omitted by the pl_queue code, but that fix exposed this.
While it's technically API misuse on mpv side, due to the mpv vo code
having its own internal queueing and timing control, it shouldn't
actually make any difference in practice (and likely, the error message
showing up is the only meaningful bug here - the issue is entirely
cosmetic).

Configuration of filter parameters was moved from pl_filter_function (of
which the user had to make a copy) to pl_filter_config, with the
pl_filter_function remaining immutable.
Implement this new logic in a way that can reasonably exist side-by-side
with the old configuration API. Once we drop support for PL_API_VER
below 303, we can drastically simplify this code.
The manual currently says that if dscale is unset, --scale will be
applied. However, this only works at init time. If you change the dscale
filter to be empty later, vo_gpu will segfault and vo_gpu_next will
throw an error and refuse the changes. That's because when the option is
unset at runtime, the value becomes "" not NULL and the vo's never
accounted for this. Fixes#12031.
We wanted to preserve the libplacebo v5.264.0 requirement for gpu_next
for this release, since this is the what most Linux distributions are shipping.
The VLC 3 <-> libplacebo v6 situation is an additional reason distros are not
likely to ship the newest libplacebo release soon.
This reverts commit b73d96776c.
--no-config should prevent loading user files of any type: configs,
cache, etc. For cache files, this case wasn't properly handled and it
was assumed they would always get something. vo_gpu's shader cache
actually already handles this, so it was left untouched. In theory,
demuxer cache should never have this issue because saving it to disk is
disabled by default (and likely that will never change), but go ahead
and change it for consistency's sake. Fixes some segfaults with
--no-config and various combinations of settings (particularly
--vo=gpu-next).
