Instead of hard-coding a big list, move some of the functionality
to csputils. Affects both the auto-guess blacklist and the peak
estimation.
Also update the comments.
Too many "exceptions" these days, it's easier to just hard-code a
whitelist instead of a blacklist. And besides, it only really makes
sense to avoid adaptation for BT.601 specifically, since that's the one
we auto-guess based on the resolution.
I'm not even sure why we ever consulted *_src to begin with, since that
just describes the current image format - and not the original metadata.
(And in fact, we specifically had logic to work around the impliciations
this had on linear scaling)
image_params is *the* authoritative source on the intended (i.e.
reference) image metadata, whereas *_src may be changed by previous
passes already. So only consult image_params for picking auto-generated
values.
Also, add some more missing "wide gamut" and "non-gamma" curves to the
autoconfig blacklist. (Maybe it would make sense to move this list to
csputils in the future? Or perhaps even auto-detect it based on the
associated primaries)
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 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.
The main framebuffer is not the default framebuffer for the dxinterop
backend. Bind the main framebuffer and use the appropriate attachment
when reading the window content.
Fix#3284
The GL_ARB_timer_query extension and thus the GL_TIME_ELAPSED constant
don't exist for GLES.
For ES the EXT_disjoint_timer_query is used so take the constant from
that else provide the constant manually.
See pr #3216 which introduced this error.
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.)
This can also remove all the stuff for lazily attaching the texture. It
doesn't matter if the dxinterop backend changes the bound framebuffer
during a VOCTRL, since the renderer does not rely on the GL state being
preserved.
The previous few commits changed sd_lavc.c's output to packed RGB sub-
images. In particular, this means all sub-bitmaps are part of a larger,
single bitmap. Change the vo_opengl OSD code such that it can make use
of this, and upload the pre-packed image, instead of packing and copying
them again.
This complicates the upload code a bit (4 code paths due to messy PBO
handling). The plan is to make sub-bitmaps always packed, but some more
work is required to reach this point. The plan is to pack libass images
as well. Since this implies a copy, this will make it easy to refcount
the result.
(This is all targeted towards vo_opengl. Other VOs, vo_xv, vo_x11, and
vo_wayland in particular, will become less efficient. Although at least
vo_vdpau and vo_direct3d could be switched to the new method as well.)
This is the ES equivalent to ARB_timer_query. It enables the performance
timers on ANGLE. All the added functions should be identical in
semantics to their desktop GL equivalents.
The OpenGL 3.0+ and ES specs are quite clear on what values are
accepted for the attachment object name parameter. And there's no
overlap for the default framebuffer. Sigh.
Probably fixes Mesa raising an error in this case and might fix#3251.
Regression by the previous vo_opengl change.
Until now, we've used system-specific API (GLX, EGL, etc.) to retrieve
the depth of the default framebuffer. (We equal this to display depth
and use the determined depth for dithering.)
We can actually retrieve this value through standard GL API, and it
works everywhere (except GLES 2 of course). This simplifies everything a
great deal.
egl_helpers.c is empty now. But I expect that some EGL boilerplate will
be moved to it, so don't remove it yet.
This was somehow done under the assumption that ANGLE would somehow
always use RG in ES2 mode. But there's no basis for this. Even if ANGLE
supports NV12 textures with drivers that do not allow for texture_rg,
this cas eis too obscure to worry about. So do the robust and correct
thing instead, and disable this code if texture_rg is not available.
This is a common idiom used in MSDN docs and Raymond Chen's example
programs to get a HINSTANCE for the current module, regardless of
whether it's an .exe or a .dll. Using GetModuleHandle(NULL) for this is
technically incorrect, since it always gets a handle to the .exe, even
when the executing code (in libmpv) is running in a .dll. In this case,
using the wrong HINSTANCE could cause namespace issues with window
classes, since CreateWindowEx uses the HINSTANCE to search for the
matching window class name.

This is mainly for the nnedi3 user shader. With all whose NN weights
hardcoded into the shader source code, the shader file could be as
large as 300 kB.
Although D3D11 video decoding is unuspported on Windows 7, the
associated APIs almost work. Where they fail is texture creation, where
we try to create D3D11_BIND_DECODER surfaces. So specifically try to
detect this situation.
One issue is that once the hwdec interop is created, the damage is done,
and it can't use another backend (because currently only 1 hwdec backend
is supported). So that's where we prevent attempts to use it.
It still can fail when trying to use d3d11va-copy (since that doesn't
require an interop backend), but at that point we don't care anymore -
dxva2(-copy) is tried before that anyway.
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)
When using --hwdec=auto, systems that don't provide
D3D11_CREATE_DEVICE_VIDEO_SUPPORT, which probably includes all Windows
Vista and 7 systems, will print an error message. Reduce the log level
to verbose when probing and skip the error message entirely if d3d11.dll
is not present.
This commit is in a similar spirit to 991af7d.
The default behavior of vo_opengl has pretty much always been 'show the
source colors as-is, without caring to adapt it to the target device'.
This decision is mostly based on the fact that if we do anything else,
lots of people will complain.
With the rise of content like BT.2020, however, it turns out more people
complain about this content being very desaturated than people complain
about this content not matching VLC - so let's just map ultra-wide gamut
content back down to standard gamut by default.
Instead of measuring the actual upload time, this instead measures the
time needed to render + map the texture via vdpau. These numbers are
still useful, since they're part of the critical path.
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.)

To avoid blocking the CPU, we use 8 time objects and rotate through
them, only blocking until the last possible moment (before we need
access to them on the next iteration through the ring buffer). I tested
it out on my machine and 4 query objects were enough to guarantee
block-free querying, but the extra margin shouldn't hurt.
Frame render times are just output at the end of each frame, via MP_DBG.
This might be improved in the future. (In particular, I want to expose
these numbers as properties so that users get some more visible feedback
about render times)
Currently, we measure pass_render_frame and pass_draw_to_screen
separately because the former might be called multiple times due to
interpolation. Doing it this way gives more faithful numbers. Same goes
for frame upload times.
When ANGLE is using D3D11 and not running in DirectComposition mode,
DXGI will hook the video window's message loop and override Alt+Enter to
trigger a transition to exclusive fullscreen mode (which doesn't even
work with mpv's renderer for some reason.) This behaviour can be
disabled by getting a pointer to the IDXGIFactory associated with the
D3D11 device and calling MakeWindowAssociation with the appropriate
flags.
Enable m_sub_options_copy() to copy nested sub-options, and also enable
it to create an option struct from defaults. We can get rid of most of
the crap in assign_options() now.
Calling handle_scaler_opt() to get a static allocation for scaler name
is still needed. It's moved to reinit_scaler(), which seems to be a
better place for it. Without it, dangling pointers could be created when
options are changed. (And in fact, this fixes possible dangling pointers
for window.name.) In theory we could create a dynamic copy, but that
seemed even more messy.
Chance of regressions.
Commit 026b75e7 actually enabled changing icc options at runtime (via
vo_cmdline), but it didn't quite work. In particular, changing the icc-
profile option just kept the old profile, because it was cached
accordingly.
As part of this, change gl_lcms.opts from a struct to a pointer to a
struct. We properly copy it, instead of allowing possibly dangling
strings, like it was done in a working but unclean way before.
Also, reinit the whole rendering chain when the auto icc profile
changes, just like it's done when icc options are changed.
Passing the bstr thing as pointer makes no sense. Everywhere else bstr
structs are passed by value because they're so small. Only when it's
supposed to receive a return value they're not.
Originally, video.c did not access any CMS things (other than lut3d
being set on it), but this has changed. In practice, almost all accesses
to it have moved to video.c. vo_opengl only created it, and set the auto
icc profile path.
Complete the move.
Some things wrt. option handling are a bit fishy. (But when is this not
the case.)
icc-profile-auto was not tested, but the distributed human CI will take
care of it.
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).
