This requires changing the pixel upload alignment because the odd sizes
might not be aligned to multiples of 4.
Anyway, the restriction has no real benefit and the sizes in between 32
and 64 might be worth using, so just drop it.
Following testing after ebe798a, this is a more than sufficient size to
cover our use case.
The old default was a drop of about 58 dB PSNR using the old code, and
this new default is about 65 dB PSNR, so it's actually an improvement
despite resulting in a smaller size.
There was no outlier whatsoever when comparing sizes around the 64
neighbourhood (with every step corresponding to a PSNR drop of about
0.07 dB), so I picked this since it's a power of two and requires no
change to the current 3dlut-size parsing logic.
I also tested smaller sizes such as 32x32x32 which performed almost as
well on colorful samples, but this results in noticeable black boost in
the dark regions, which is pretty undesirable. Therefore, we should
avoid going much further below 64x64x64.
Either way, this new size is so fast to compute that the 3dlut cache is
almost useless on my end. In fact, it might even be slower to load the
profile from the cache than to recompute it from scratch. (For caches on
a disk. For cache on a tmpfs, it makes no difference)
mixer.c didn't really deserve to be separate anymore, as half of its
contents were unnecessary glue code after recent changes. It also
created a weird split between audio.c and af.c due to the fact that
mixer.c could insert audio filters. With the code being in audio.c
directly, together with other code that unserts filters during runtime,
it will be possible to cleanup this code a bit and make it work like the
video filter code.
As part of this change, make the balance code work like the volume code,
and add an option to back the current balance value. Also, since the
balance semantics are unexpected for most users (panning between the
audio channels, instead of just changing the relative volume), and there
are some other volumes, formally deprecate both the old property and the
new option.
Old-style commands using _ as separator (e.g. show_progress) were still
used in some places, including documentation and configuration files.
This commit updates all such instances to the new style (show-progress)
so that commands are easier to find in the manual.
Since it turns out that knowing what exactly a file was tagged with can
be useful for debugging purposes, expose this as a property so I can
check it more easily.
This is mostly useful for sig-peak (since nom-peak is currently entirely
calculated by us), but I added both for consistency.
Drop the code for switching the volume options and properties between
af_volume and AO volume controls. interface-changes.rst mentions the
changes in detail.
Do this because this was exceedingly complex and had other problems as
well. It was also very hard to test. It's just not worth the trouble.
Some leftovers like AOCONTROL_HAS_PER_APP_VOLUME will be removed at a
later point.
Fixes#3322.
Although it appears to be accepted by the function, MSGL_STATUS messages
are never passed to the client API. Consequently "status" has the same
meaning as "v" and is useless.
Working towards refcounted sub images, and also for removing bitmap
packers from VOs.
I'm not sure why we even have this overlay-add command. It was sort of
"needed" before opengl-cb was introduced, and before Lua scripts could
put ASS drawings on OSD without conflicting with the OSC. But now trying
to use it doesn't make too much sense anymore.
Still keep it because we're trying to be nice, but throw performance out
of the window. Now image data is copied 2 more times before displaying
it. This also makes using the command a bit simpler.
User request and not that hard. Closes#3157.
Note that FFmpeg doesn't support this and there's no signalling in HEVC
etc., so the only way users can access it is by using vf_format
manually.
Mind: This encoding uses full range values, not TV range.
This is actually not entirely trivial since it involves negative Yxy
coordinates, so the CMM has to be capable of full floating point
operation. Fortunately, LittleCMS is, so we can just blindly implement
it.
Most devices seems to require special signalling (e.g. via HDMI
metadata) to actually decode HDR signals and treat them as such, so it's
probably worth warning the potential user about the fact that mpv pretty
definitely does *not* set any of this metadata signalling.
This HDR function is unique in that it's still display-referred, it just
allows for values above the reference peak (super-highlights). The
official standard doesn't actually document this very well, but the
nominal peak turns out to be exactly 12.0 - so we normalize to this
value internally in mpv. (This lets us preserve the property that the
textures are encoded in the range [0,1], preventing clipping and making
the best use of an integer texture's range)
This was grouped together with SMPTE ST2084 when checking libavutil
compatibility since they were added in the same release window, in a
similar timeframe.
Until now, we've always converted vdpau video surfaces to RGB, and then
mapped the resulting RGB texture. Change this so that the surface is
mapped as NV12 plane textures.
The reason this wasn't done until now is because vdpau surfaces are
mapped in an "interlaced" way as separate fields, even for progressive
video. This requires messy reinterleraving. It turns out that even
though it's an extra processing step, the result can be faster than
going through the video mixer for RGB conversion.
Other than some potential speed-gain, doing this has multiple other
advantages. We can apply our own color conversion, which is important in
more complex cases. We can correctly apply debanding and potentially
other processing that requires chroma-specific or in-YUV handling.
If deinterlacing is enabled, this switches back to the old RGB
conversion method. Until we have at least a primitive deinterlacer in
vo_opengl, this will stay this way. The d3d11 and vaapi code paths are
similar. (Of course these don't require any crazy field reinterleaving.)
Instead of having 9 different properties, requiring 18 different
VOCTRLs to read them all, they are now exposed as a single property.
This is not only cleaner (since they're all together) but also allows
querying all 9 of them with only a single VOCTRL (by using
mp.get_property_native).
(The extra factor of 2 was due to an extra query being needed to get the
type, which is now also unnecessary)
This makes it much easier to access performance metrics from within a
lua script, and also makes it easier to just show a readable, formatted
version via show-text.
User hooks can now use an extra WHEN expression to specify when the
shader should be run. For example, this can be used to only run a chroma
scaling shader `WHEN CHROMA.w LUMA.w <`.
There's a slight semantics change to user shaders: When trying to bind a
texture that does not exist, a shader will now be silently skipped
(similar to when the condition is false) instead of generating an error.
This allows shader stages to depend on an optional earlier stage without
having to copy/paste the same condition everywhere.
(In other words: there's an implicit condition on all of the bound
textures existing)
This is plumbed through a new VOCTRL, VOCTRL_PERFORMANCE_DATA, and
exposed as properties render-time-last, render-time-avg etc.
All of these numbers are in microseconds, which gives a good precision
range when just outputting them via show-text. (Lua scripts can
obviously still do their own formatting etc.)

Instead of implicitly resetting the options to defaults and then
applying the options, they're always applied on top of the current
options (in the same way adding new options to the CLI command line
will).
This does not apply to vo_opengl_cb, because that has an even worse mess
which I refuse to deal with.
This algorithm works really well. Setting it is a much better
"out-of-the-box" experience than just clipping, which will always look
ugly.
In other words, with this default, users of mpv will just be able to
play HDR content without even realizing it's HDR (pretty much).
Instead of doing HDR tone mapping on an ad-hoc basis inside
pass_colormanage, the reference peak of an image is now part of the
image params (alongside colorspace, gamma, etc.) and tone mapping is
done whenever peak_src != peak_dst.
To get sensible behavior when mixing HDR and SDR content and displays,
target-brightness is a generic filler for "the assumed brightness of SDR
content".
This gets rid of the weird display_scaled hack, sets the framework
for multiple HDR functions with difference reference peaks, and allows
us to (in a future commit) autodetect the right source peak from
the HDR metadata.
(Apart from metadata, the source peak can also be controlled via
vf_format. For HDR content this adjusts the overall image brightness,
for SDR content it's like simulating a different exposure)
Main use: deinterlacing.
I'm not sure how to select the deinterlacing mode at all. You can
enumate the available video processors, but at least on Intel, all of
them either signal support for all deinterlacers, or none (the latter is
apparently used for IVTC). I haven't found anything that actually tells
the processor _which_ algorithm to use.
Another strange detail is how to select top/bottom fields and field
dominance. At least I'm getting quite similar results to vavpp on Linux,
so I'm content with it for now.
Future plans include removing the D3D11 video processor use from the
ANGLE interop code.
This has often been requested for use on OSD. I don't really like having
such "special" properties, but whatever. Hopefully this will be the only
case.
Untested because I'm too damn lazy.
Fixes#2828.
Remove the opengl-hq option default that caused it not to autoselect
ANGLE (unlike --vo=opengl). Details see commit d5df90a2.
Back then the intention was to use ANGLE by default, since it integrates
much nicer with the Windows compositor (instead of native OpenGL, which
tends to cause crazy glitches). On the other hand, many opengl-hq
capabilities are not available with older ANGLE builds, so it didn't
make any sense to autoselect ANGLE for it.
With the GL_EXT_texture_norm16 extension recently added to ANGLE, it has
essentially reached feature parity to desktop GL for the subset we are
using. (Even the integer texture hack for high bit depth input could be
dropped now.)
It (probably) still does not support nnedi3, due to the weird way the NN
coefficients are imported. Also, it uses half-floats instead of 16 bit
fixed-point textures for technical reasons, which implies about 5 bits
of precision loss. If anyone actually manages to distinguish the two
dithering texture formats in a double-blind test, I will fix it.
