82231fd74d mentioned that for the "rot"
transform flip=true must be set, which "makes no sense at all".
The reason this is happening is that the rotation matrix calculation
is only valid for the 2D coordinate system where y axis is 90 degrees
counterclockwise from x axis, but the coordinate system of chroma
offset has its origin at top-left so it is the opposite, which results
in the rotation going to the opposite way. Setting flip=true fixes the
rotation direction, but results in a flipped y coordinate.
Fix this by reversing the rotation angle for chroma offset rotation
matrix calculation. This also allows removing some duplicated code.
This allows Tab completing them in the console and zsh, and using cycle
scale.
jinc is also added to --tscale=help's output, while before it was
missing because validate_scaler_opt() skipped filter windows with the
same name as a filter kernel, but the jinc kernel was skipped with
--tscale because it is polar.
Most of these are pretty obscure things that were replaced a long time
ago. The special messages they were printing are also not really useful
at all so just remove them.
No need to reset mp_pass_perf which is only read when desc.len > 0.
This avoids zeroing >16384 uint64_t's every time it's called.
Profiling shows that this reduces CPU usage for frame rendering by ~4%.
For image formats with 2 or more chroma planes such as YU12, there is
a plane merging pass for these planes calling finish_pass_tex which
does a format conversion. After this conversion, the cscale shader
afterwards works properly.
However, for image formats with only 1 chroma plane (semi-planar formats),
including NV12 and P010, this merging pass is never called, which breaks
the cscale shader afterwards if the video is rotated with subsampled
chroma.
Fix this by adding an explicit conversion pass if this situation is
detected after the pre-scale hooks, so if there are shaders hooking on
CHROMA (like the deband filter) and the conversion is done by pass_hook
already, this conversion won't be called.
The opt validator functions are casted to generic validator, which has
erased type for value. Calling function by pointer of different
definition is an UB.
Avoid that by generating wrapper function that does proper argument type
conversion and calls validator function. Type erased functions have
mangled type in the name.
Fixes UBSAN failures on Clang 17, which enabled fsanitize=function by
default.
The --alpha option currently covers two related but different concepts:
whether or not to ignore the alpha component and possibly blending it
with a background. Because of the way the option currently works, it is
impossible to have a transparent window (which requires setting
--alpha=yes) while blending it with the background at the same time. To
solve this, let's rework it so it it superseded by the background
option.
--background controls what kind of background to set for the image if
possible. It can be blended with the set background color, with tiles,
or not blended at all (the last one is still broken on X11/mesa except
for GLX, *sigh*). In this new paradigm, --alpha=no has no real purpose
because you can simply set the background to color and whatever color
you want for exactly the same effect. So the option is removed. Instead,
the hint set by windowing backends (i.e. setting
ra_ctx->opts.want_alpha) can by done with the --background option.
As an aside, the colors in vo_gpu are currently bugged due to not
pre-multiplying the alpha and it seems no one ever noticed. The next
commit fixes that. vo_gpu_next support happens latter since it requires
new things from libplacebo.
Fixes#9615.
Previous fix only worked when the video output doesn't have vertical
black bars. This fixes the cases like fullscreen, video-zoom etc.

When doing the dithering pass, the fragment coordinate is queried, but
doesn't take the fbo texture flipped property into account. This results
in different dithering patterns when toggling between fbo flipped and
non-flipped state. This can be reproduced with --vo=gpu --gpu-api=opengl
and easily seen with --dither-depth=1 when toggling between playing and
pausing.
Fix this by flipping the fragment y coordinate if the fbo is flipped
when calculating dithering coordinate.
When redrawing cached frames while the fbo texture is flipped,
the texture after drawing to screen pass will be flipped when blitting.
However, when rendering the checkerboard, the fragment coordinate
doesn't take this into account, so the coordinate before flipping is used,
resulting in different checkerboard location when toggling between
flipped and non-flipped state. This can be reproduced with --vo=gpu
and --gpu-api=opengl: the checkerboard patterns when playing and
pausing are different (vertically flipped).
Fix this by flipping the fragment y coordinate if the fbo is flipped
when calculating checkerboard coordinate.
When adding things like brightness or gamma, the video obviously needs a
redraw if paused. This happened to work in the normal case because the
OSD notification triggered a redraw, but if you use no-osd the picture
won't change. Fix this by adding another option flag, UPDATE_VIDEO, and
simply signalling we want a redraw. This gets handled along with the
normal osd redrawing check in the playloop so something like "no-osd add
gamma 1" actually works.
281b1d8999 introduced a stack use after
scope because dest_fbo can be reassigned a new pointer and then be used
by pass_draw_to_screen outside of that scope where the pointer is no
longer valid. Fix this by rearranging the variables so the assignment is
done in the same scope as the pass_draw_to_screen call instead.
This commit replaces all uses of sig_peak and maps all HDR metadata.
Form notable changes mixed usage of maxCLL and max_luma is resolved and
not always max_luma is used which makes vo_gpu and vo_gpu_next behave
the same way.
There was assumption in the code that default settings are compatible
with dumb mode and are only one that should be used in this case.
Force bilinear if dumb mode is enabled.
We've got an ungodly amount of OPT_REPLACED and OPT_REMOVED sitting
around in the code. This is harmless, but the vast majority of these are
ancient. 26f4f18c06 is the last commit
that touched the majority of these and of course that only changed how
options were declared so all of this stuff was deprecated even before
that. No use in keeping these, so just delete them all. As an aside,
there was actually a cocoa_opts but it had only a single option which
was replaced by something else and empty otherwise. So that entire thing
was just simply removed. OPT_REPLACED/OPT_REMOVED declarations that were
added in 0.35 or later were kept as is.
This probably makes `vo_gpu` tone mapping worse, or something, but who
cares. The status quo for a while now has been to use `vo_gpu_next` if
you care about HDR rendering at all.

This new filter is slightly sharper, and significantly faster, than
mitchell. It also tends to preserve detail better. All in all, there is
no reason not to use it by default, especially from a performance PoV.
(In vo_gpu_next, hermite is implemented efficiently using hardware
accelerated bilinear interpolation)

The goal is to provide simple to understand quality/performance level
profiles for the users.
Instead of default and gpu-hq profile. There main profiles were added:
- fast: can run on any hardware
- default: balanced profile between quality and performance
- high-quality: out of the box high quality experience. Intended
mostly for dGPU.
Summary of three profiles, including default one:
[fast]
scale=bilinear
cscale=bilinear (implicit)
dscale=bilinear
dither=no
correct-downscaling=no
linear-downscaling=no
sigmoid-upscaling=no
hdr-compute-peak=no
[default] (implicit mpv defaults)
scale=lanczos
cscale=lanczos
dscale=mitchell
dither-depth=auto
correct-downscaling=yes
linear-downscaling=yes
sigmoid-upscaling=yes
hdr-compute-peak=yes
[high-quality] (inherits default options)
scale=ewa_lanczossharp
cscale=ewa_lanczossharp (implicit)
hdr-peak-percentile=99.995
hdr-contrast-recovery=0.30
allow-delayed-peak-detect=no
deband=yes
scaler-lut-size=8
No need for this since it's entirely redundant with just changing the
filter radius directly. In fact, that's the whole *point* of the filter
radius - it does not modify the filter, it modifies the scaling of the
window.
Of course, this does not work for non-resizable kernels. But, really,
who cares?
