Make the VO<->decoder interface capable of supporting multiple hwdec
APIs at once. The main gain is that this simplifies autoprobing a lot.
Before this change, it could happen that the VO loaded the "wrong" hwdec
API, and the decoder was stuck with the choice (breaking hw decoding).
With the change applied, the VO simply loads all available APIs, so
autoprobing trickery is left entirely to the decoder.
In the past, we were quite careful about not accidentally loading the
wrong interop drivers. This was in part to make sure autoprobing works,
but also because libva had this obnoxious bug of dumping garbage to
stderr when using the API. libva was fixed, so this is not a problem
anymore.
The --opengl-hwdec-interop option is changed in various ways (again...),
and renamed to --gpu-hwdec-interop. It does not have much use anymore,
other than debugging. It's notable that the order in the hwdec interop
array ra_hwdec_drivers[] still matters if multiple drivers support the
same image formats, so the option can explicitly force one, if that
should ever be necessary, or more likely, for debugging. One example are
the ra_hwdec_d3d11egl and ra_hwdec_d3d11eglrgb drivers, which both
support d3d11 input.
vo_gpu now always loads the interop lazily by default, but when it does,
it loads them all. vo_opengl_cb now always loads them when the GL
context handle is initialized. I don't expect that this causes any
problems.
It's now possible to do things like changing between vdpau and nvdec
decoding at runtime.
This is also preparation for cleaning up vd_lavc.c hwdec autoprobing.
It's another reason why hwdec_devices_request_all() does not take a
hwdec type anymore.
nvdec aka cuvid aka cuda should work much better than vdpau, and support
newer codecs (such as vp9), and more advanced surface formats (like 10
bit).
This requires moving the d3d hwaccels in the autoprobe order, since on
Windows, d3d decoding should be preferred over nvidia proprietary stuff.
Users of older drivers will need to force --hwdec=vdpau, since it could
happen that the vo_gpu cuda hwdec interop loads (so the vdpau interop is
not loaded), but the hwdec itself doesn't work.
I expect this does not break AMD (which still needs vdpau for vo_gpu
interop, until libva is fixed so it can fully support AMD).
This has stopped being useful a long time ago, and it's the only GPL
source file in the vo_gpu source directories. Recently it wasn't even
loaded at all, unless you forced loading it.
The D3D11_CREATE_DEVICE_BGRA_SUPPORT flag doesn't enable support for
BGRA textures. BGRA textures will be supported whether or not the flag
is passed. The flag just fails device creation if they are not supported
as an API convenience for programs that need BGRA textures, such as
programs that use D2D or D3D9 interop. We can handle devices without
BGRA support fine, so don't bother with the flag.
For consistency with already implemented shcore.dll
function loading in w32->api:
Moved loading of imm32.dll to w32_api_load, and declare
pImmDisableIME function pointer in the w32->api struct.
Removed unloading of imm32.dll.
Seems like the last refactor to this code broke playing flipped images,
at least with --opengl-pbo --gpu-api=opengl.
Flipping is rather a shitmess. The main problem is that OpenGL does not
support flipped uploading. The original vo_gl implementation considered
it important to handle the flipped case efficiently, so instead of
uploading the image line by line backwards, it uploaded it flipped, and
then flipped it in the renderer (basically the upload path ignored the
flipping). The ra code and backends probably have an insane and
inconsistent mix of semantics, so fix this by never passing it flipped
images in the first place.
In the future, the backends should probably support flipped images
directly.
Fixes#5097.
Like the manual says, this is technically undefined behaviour. See:
https://msdn.microsoft.com/en-us/library/windows/desktop/ff476085.aspx
In particular, MSDN says texture arrays created with the BIND_DECODER
flag cannot be used with CreateShaderResourceView, which means they
can't be sampled through SRVs like normal Direct3D textures. However,
some programs (Google Chrome included) do this anyway for performance
and power-usage reasons, and it appears to work with most drivers.
Older AMD drivers had a "bug" with zero-copy decoding, but this appears
to have been fixed. See #3255, #3464 and http://crbug.com/623029.
The shader cache in ra_d3d11 caches the result of shaderc, crossc and
the D3DCompiler DLL, so it should be invalidated when any of those
components are updated. This should make the cache more reliable, which
makes it safer to enable gpu-shader-cache-dir. Shader compilation is
slow with D3D11, so gpu-shader-cache-dir is highly necessary
Some shaders take a _long_ time to compile with the Direct3D compiler.
The ANGLE backend had this problem too, to a certain extent. Logging
should help identify which shaders cause long stalls and could also help
with benchmarking ways of reducing compile times.
ra_d3d11 uses the SPIR-V compiler to translate GLSL to SPIR-V, which is
then translated to HLSL. This means it always exposes the same GLSL
version that the SPIR-V compiler supports (4.50 for shaderc/glslang.)
Despite claiming to support GLSL 4.50, some features that are tied to
the GLSL version in OpenGL are not supported by ra_d3d11 when targeting
legacy Direct3D feature levels.
This includes two features that mpv relies on:
- Reading from gl_FragCoord in the fragment shader (requires FL 10_0)
- textureGather from any texture component (requires FL 11_0)
These features have been exposed as new RA caps.
This is a new RA/vo_gpu backend that uses Direct3D 11. The GLSL
generated by vo_gpu is cross-compiled to HLSL with SPIRV-Cross.
What works:
- All of mpv's internal shaders should work, including compute shaders.
- Some external shaders have been tested and work, including RAVU and
adaptive-sharpen.
- Non-dumb mode works, even on very old hardware. Most features work at
feature level 9_3 and all features work at feature level 10_0. Some
features also work at feature level 9_1 and 9_2, but without high-bit-
depth FBOs, it's not very useful. (Hardware this old is probably not
fast enough for advanced features anyway.)
Note: This is more compatible than ANGLE, which requires 9_3 to work
at all (GLES 2.0,) and 10_1 for non-dumb-mode (GLES 3.0.)
- Hardware decoding with D3D11VA, including decoding of 10-bit formats
without truncation to 8-bit.
What doesn't work / can be improved:
- PBO upload and direct rendering does not work yet. Direct rendering
requires persistent-mapped PBOs because the decoder needs to be able
to read data from images that have already been decoded and uploaded.
Unfortunately, it seems like persistent-mapped PBOs are fundamentally
incompatible with D3D11, which requires all resources to use driver-
managed memory and requires memory to be unmapped (and hence pointers
to be invalidated) when a resource is used in a draw or copy
operation.
However it might be possible to use D3D11's limited multithreading
capabilities to emulate some features of PBOs, like asynchronous
texture uploading.
- The blit() and clear() operations don't have equivalents in the D3D11
API that handle all cases, so in most cases, they have to be emulated
with a shader. This is currently done inside ra_d3d11, but ideally it
would be done in generic code, so it can take advantage of mpv's
shader generation utilities.
- SPIRV-Cross is used through a NIH C-compatible wrapper library, since
it does not expose a C interface itself.
The library is available here: https://github.com/rossy/crossc
- The D3D11 context could be made to support more modern DXGI features
in future. For example, it should be possible to add support for
high-bit-depth and HDR output with DXGI 1.5/1.6.
Backported from @haasn's change to libplacebo, except in the current RA,
there's nothing to indicate an ra_format can be bound as a storage
image, so there's no way to force all of these formats to have a
glsl_format. Instead, the layout qualifier will be removed if
glsl_format is NULL.
This is needed for the upcoming ra_d3d11 backend. In Direct3D 11, while
loading float values from unorm images often works as expected, it's
technically undefined behaviour, and in Windows 10, it will cause the
debug layer to spam the log with error messages. Also, apparently in
GLSL, the format name must match the image's format exactly (but in
Direct3D, it just has to have the same component type.)
Backported from @haasn's change to libplacebo. More flexible than the
previous "shared || non-shared" distinction. The extra flexibility is
needed for Direct3D 11, but it also doesn't hurt code-wise.
For some reason vo_lavc's draw_image can buffer the frame and encode it
only later. Also, there is logic for rendering the OSD (i.e. subtitles)
only when needed.
In theory this can lead to subtitles being pruned before it tries to
render them (as the subtitle logic doesn't know that the VO still needs
them later), although this probably never happens in reality.
The worse issue, that actually happened, is that if the last frame gets
buffered, it attempts to render subtitles in the uninit callback. At
this point, the subtitle decoder is already torn down and all subtitles
removed, thus it will draw nothing. This didn't always happen. I'm not
sure why - potentially in the working cases, the frame wasn't buffered.
Since this logic doesn't have much worth, except a minor performance
advantage if frames with subtitles are dropped, just remove it.
Hopefully fixes#4689.
Repeating frames (for display-sync) is not supposed to render the entire
frame again. When using hardware decoding, it unfortunately did: the
renderer uses the frame ID to check whether the frame data changed, and
unmapping the hwdec frame clears it.
Essentially reverts commit 761eeacf5407cab07. Back then I probably
thought it would be a good idea to release the hwdec image quickly in
order to return it to the decoder, but they're referenced anyway.
This should increase the performance and reduce GPU work.
Normally such code is didsabled by have_mglsl==false in
check_gl_features(), but apparently not this one.
Just fix it. Seems also more readable.
Fixes#5069.
Apparently this is required, but it doesn't check for it. To be fair,
this was tested by creating a compatibility context and pretending it's
GL 2.1. GL_ARB_shader_storage_buffer_object actually requires GL 4.0 or
up, but GL_ARB_uniform_buffer_object requires only GL 2.0.
vo_gpu.c will call gl_video_icc_auto_enabled() to check whether it
should retrieve the ICC profile. But the value returned by this function
will be outdated, because gl_video_update_options() is not called yet.
Change the order of function calls so that this is done after updating
the options.
(This is fairly chaotic, but I guess this code will be refactored a
dozen of times anyway in the future.)
This is just a dumb consequence of HWDEC_ types somehow being part of
both decoder and VO. Obviously, the VO should only care about supporting
specific hardware surface types or providing specific device types, but
until they are separated, stupid unintuitive mismatches will occur.
See manpage additions.
(In ffmpeg-mpv and Libav, this is still called "cuvid". Libav won't work
yet, because it has no frame params support yet, but this could get
fixed soon.)
params->rc was ignored in the calculation for the buffer size. I fucking
hate this stupid ra_tex_upload signature where *rc is randomly relevant
or not.
Coverity complains about this, but it's probably a false positive.
Anyway, rewrite it in a slightly more readable way. Now it's more
obvious that it is correct.
Comparing mpv's implementation against the ACES ODR reference samples
and algorithms, it seems like they're happy desaturating highlights
_way_ more aggressively than mpv currently does. And indeed, looking at
some example clips like The Redwoods (which is actually well-mastered),
the current desaturation produces unnatural-looking brightness fringes
where the sky meets the treeline.
Adjust the algorithm to make it apply to a much larger, more gradual
brightness region; and change the interpretation of the parameter. As a
bonus, the new parameter is actually sanely scaled (higher values = more
desaturation). Also, make it scale based on the signal level instead of
the luminance, to avoid under-desaturating bright blues.
This commit allows to use the AV_PIX_FMT_DRM_PRIME newly introduced
format in ffmpeg that allows decoders to provide an AVDRMFrameDescriptor
struct.
That struct holds dmabuf fds and information allowing zerocopy rendering
using KMS / DRM Atomic.
This has been tested on RockChip ROCK64 device.
Since we divide by it in a couple of places and compositors can be crazy,
its better to be safe than sorry.
Also checks cursor spawn durinig init (pointless since it does again on
cursor entry but its more correct).
It seems the cursor hadn't had its position properly adjusted when scaled.
Hence, bring back correct buffer scaling to make the cursor look fine.
Also the cursor surface now gets created sooner so that's better.
Regression since ec6e8a31e092a1d. Removal of the explicit else case
always applies the conversion to premultiplied alpha in the else branch.
We want to scale with multiplied alpha, but we don't want to multiply
with alpha again on top of it.
Fixes#4983, hopefully.
This should be functionally identical to rgba16f, since the formats only
differ in their representation on the CPU, but it could be useful for RA
backends that don't expose rgba16f, like Vulkan. It's definitely useful
for the WIP D3D11 backend.
With video paused, changing the brightness controls (or similar) would
sometimes not rerender the video frame. So the OSD would redraw, but the
video wouldn't change. This is caused by output caching, and a redraw
request is free to return the cached frame. Change it such to invalidate
the cached frame if any of the options or the equalizer change.
In theory, gl_video_reset_surfaces() could be called if the equalizer
changes - this would apparently force interpolatzion to redraw all
frames. But this looks kind of crappy when changing the equalizer during
playback. It'll "eventually" use the correct settings anyway, and when
paused interpolation is off.
This was confusing at best. Change it to output the actual choices.
(Seems like in the end it's always me who has to clean up other people's
bullshit.)
Context names were not unique - but they should be, so fix it. The whole
point of the original --opengl-backend option was to side-step the
tricky auto-detection, so you know exactly what you get. The goal of
this commit is to make --gpu-context work the same way. Fix the
non-unique names by appending "vk" to the names.
Keep in mind that this was not suitable for slecting the "UI" backend
anyway, since "x11" would force GLX, whereas people on not-NVIDIA
actually want "x11egl". Users trying to use --gpu-context=x11 to force
the X11 backend would always end up with GLX, which would at least break
VAAPI hardware decoding for them. Basically the idea that this option
could select the "UI" type is completely broken - it selects an
implementation, which implies a UI. Selecting the UI type This would
require a separate mechanism. (Although in theory this separate
mechanism could be part of the --gpu-context option - in any case,
someone would have to implement it.)
To achieve help output that can actually be understood, just duplicate
the code. Most of that code is duplicated anyway, and trying to share
just the list code with the result of making the output unreadable
doesn't make too much sense. If we wanted to save code/effort, we could
just remove the help output altogether.
--gpu-api has non-unique entries, and it would be nice to group them
(e.g. list all OpenGL capable contexts with "opengl"), but C makes this
simple idea too much of a pain, so don't do it.
Also remove a stray tab from the android entry on the manpage.
Every compositor (including toy compositors) has had support for wl_output v2
since forever, so there's little point in supporting degraded output for 5 year
old releases (especially considering we require zxdg6 which is far more recent).
This adds symbol information to the generated SPIR-V, which shows up in
the SPIR-V assembly dump. It's also useful for potential RA backends
that use SPIRV-Cross, since the symbol information is used in the
generated shader source.
This should actually cover all of them, if you take into account that
some unchanged GPL source files include header files with such checks.
Also this was done already for the libaf derived code.
This is only for "safety" and to avoid misunderstandings.
It turns out compositors which do scaling scale the cursor as well,
so every single surface needs to get scaled too.
Also, 32 corresponds to the default size for both GTK+ and KDE.
This new interface in libva2 offers a cleaner way to export surfaces
which can then be imported to EGL. In particular, this works with
the Mesa driver, so we can have proper playback without a pointless
download and upload on AMD cards.
This change does nothing with libva1, and will fall back to the
libva1 interface (vaDeriveImage() + vaAcquireBufferHandle()) if
vaExportSurfaceHandle() is not present.
At the moment, rendering on Android requires ``--vo=opengl-cb`` and
a lot of java<->c++ bridging code to receive the receive and react to
the render callback in java. Performance also suffers with opengl-cb,
due to the overhead of context switching in JNI.
With this patch, Android can render using ``--vo=gpu --gpu-context=android``
(after setting ``--wid`` to point to an android.view.Surface on-screen).
MediaCodec uses a fixed number of output buffers to hold frames, and
expects that output buffers will be released as soon as possible. Once
rendered, the underlying frame is automatically released and cannot be
reused or rerendered.
The new VO_CAP_NOREDRAW forces mpv to release frames immediately after
they are rendered or dropped, to ensure that MediaCodec decoder does not
run out of buffers and stall out.
This commit:
- Implements output tracking (e.g. monitor plug/unplug)
- Creates the surface during registry (no other dependencies)
- Queues the callback immediately after surface creation
- Cleaner and better event handling (functions return directly)
- Better reconfigure handling (resizes reduced to 1 during init)
- Don't unnecessarily resize (if dimensions match)
Apart from that fixes 2 potential memory leaks (mime type and window
title), 2 string ownership issues (output name and make need to be
dup'd), fixes some style issues (switches were indented) and finally
adds messages when disabling/enabling idle inhibition.
The callback setter function was removed in preparation for the commit
which will use the frame event cb because it was unnecessary.
The VO code resets each flag individually, and it doesn't do it for this one.
Also make the prints use the struct names rather than the hardcoded ones,
forgot to add those to the last wayland_common commit.
The wayland code was written more than 4 years ago when wayland wasn't
even at version 1.0. This commit rewrites everything in a more modern way,
switches to using the new xdg v6 shell interface which solves a lot of bugs
and makes mpv tiling-friedly, adds support for drag and drop, adds support
for touchscreens, adds support for KDE's server decorations protocol,
and finally adds support for the new idle-inhibitor protocol.
It does not yet use the frame callback as a main rendering loop driver,
this will happen with a later commit.
The existing code in check_ext() avoided false positive due to
sub-strings, but allowed false negatives. Fix this with slightly better
search code, and make it available as function to other source files.
(There are some cases of strstr() still around.)
Unless FBOs are unsupported, this works. In particular, it's required to
get ICC profiles working in voluntary dumb mode. So instead of
blanket-disabling it, only disable it in the !have_fbo false case.
Originally mpv vaapi support was based on the MPlayer-vaapi patches.
These were never merged in upstream MPlayer. The license headers
indicated they were GPL-only. Although the actual author agreed to
relicensing, the company employing him to write this code did not, so
the original code is unusable to us.
Fortunately, vaapi support was refactored and rewritten several times,
meaning little code is actually left. The previous commits removed or
moved that to GPL-only code. Namely, vo_vaapi.c remains GPL-only. The
other code went away or became unnecessary mainly because libavcodec
itself gained the ability to manage the hw decoder, and libavutil
provides code to manage vaapi surfaces. We also changed to mainly using
EGL interop, making any of the old rendering code unnecessary.
hwdec_vaglx.c is still GPL. It's possibly relicensable, because much of
it was changed, but I'm not too sure and further investigation would be
required. Also, this has been disabled by default for a while now, so
bothering with this is a waste of time. This commit simply disables it
at compile time as well in LGPL mode.
Done for license reasons. vo_vaapi.c is turned into some kind of
dumpster fire, and we'll remove it as soon as I'm mentally ready for
unkind users to complain about removal of this old POS.
Seems to be fixed upstream in the nvidia driver, so it's probably a good
idea to 1. force the layout and 2. remove the warning, as it now
actually works. Users with older drivers would run into errors, but they
can still use shaderc as a replacement. (And it's not like the old
status quo was any better)
This was always set to the length of the VAO, but it should have been
set to the number of vertex attribs actually in use for this frame. No
idea how that managed to survive the test framework on nvidia/linux, but
ANGLE caught it.
This has several advantages:
1. no more redundant texcoords when we don't need them
2. no more arbitrary limit on how many textures we can bind
3. (that extends to user shaders as well)
4. no more arbitrary limits on tscale radius
To realize this, the VAO was moved from a hacky stateful approach
(gl_sc_set_vertex_attribs) - which always bothered me since it was
required for compute shaders as well even though they ignored it - to be
a proper parameter of gl_sc_dispatch_draw, and internally plumbed into
gl_sc_generate, which will make a (properly mangled) deep copy into
params.vertex_attribs.
FlagBits is just the name of the enum. The actual data type representing
a combination of these flags follows the *Flags convention. (The
relevant difference is that the latter is defined to be uint32_t instead
of left implicit)
For consistency, use *Flags everywhere instead of randomly switching
between *Flags and *FlagBits.
Also fix a wrong type name on `stageFlags`, pointed out by @atomnuker
Using renderpass layout transitions is more optimal and doesn't require
a redundant pipeline barrier.
Since our render passes are static and don't change throughout the
lifetime of a ra_renderpass, we unfortunately don't have much
flexibility here - so just hard-code SHADER_READ_ONLY_OPTIMAL as the
output format as this will be the most common case.
We also can't short-circuit the transition when we need to preserve the
framebuffer contents, since that depends on the current layout; so we
still use an explicit tex_barrier in this case. (Most optimal for this
scenario would be an input attachment anyway)
Now you need FFmpeg git, or something.
This also gets rid of the last real use of gpu_memcpy(). libavutil does
that itself. (vaapi.c still used it, but it was essentially unused,
because the code path isn't really in use anymore. It wasn't even
included due to the d3d-hwaccel dependency in wscript.)
This is apparently required to get storage images working on
windows/vulkan, and probably good practice either way. Not entirely sure
if it's the best idea to be always storing the value as 32-bit float,
but it should hardly matter in practice (since we're only writing one
sample per thread).
(Leaving them implicit requires the shaderStorageImageWriteWithoutFormat
feature to be enabled, which the windows nvidia vulkan driver doesn't
support, at least not for a GTX 670)
This makes the radeon driver shut up about frequently updating
STATIC_DRAW UBOs (--opengl-debug), and also reduces the amount of
synchronization necessary for vulkan uniform buffers.
Also add some extra debugging/tracing code paths. I went with a
flags-based approach in case we ever want to extend this.
In addition to the built-in nvidia compiler, we now also support a
backend based on libshaderc. shaderc is sort of like glslang except it
has a C API and is available as a dynamic library.
The generated SPIR-V is now cached alongside the VkPipeline in the
cached_program. We use a special cache header to ensure validity of this
cache before passing it blindly to the vulkan implementation, since
passing invalid SPIR-V can cause all sorts of nasty things. It's also
designed to self-invalidate if the compiler gets better, by offering a
catch-all `int compiler_version` that implementations can use as a cache
invalidation marker.
This time based on ra/vo_gpu. 2017 is the year of the vulkan desktop!
Current problems / limitations / improvement opportunities:
1. The swapchain/flipping code violates the vulkan spec, by assuming
that the presentation queue will be bounded (in cases where rendering
is significantly faster than vsync). But apparently, there's simply
no better way to do this right now, to the point where even the
stupid cube.c examples from LunarG etc. do it wrong.
(cf. https://github.com/KhronosGroup/Vulkan-Docs/issues/370)
2. The memory allocator could be improved. (This is a universal
constant)
3. Could explore using push descriptors instead of descriptor sets,
especially since we expect to switch descriptors semi-often for some
passes (like interpolation). Probably won't make a difference, but
the synchronization overhead might be a factor. Who knows.
4. Parallelism across frames / async transfer is not well-defined, we
either need to use a better semaphore / command buffer strategy or a
resource pooling layer to safely handle cross-frame parallelism.
(That said, I gave resource pooling a try and was not happy with the
result at all - so I'm still exploring the semaphore strategy)
5. We aggressively use pipeline barriers where events would offer a much
more fine-grained synchronization mechanism. As a result of this, we
might be suffering from GPU bubbles due to too-short dependencies on
objects. (That said, I'm also exploring the use of semaphores as a an
ordering tactic which would allow cross-frame time slicing in theory)
Some minor changes to the vo_gpu and infrastructure, but nothing
consequential.
NOTE: For safety, all use of asynchronous commands / multiple command
pools is currently disabled completely. There are some left-over relics
of this in the code (e.g. the distinction between dev_poll and
pool_poll), but that is kept in place mostly because this will be
re-extended in the future (vulkan rev 2).
The queue count is also currently capped to 1, because of the lack of
cross-frame semaphores means we need the implicit synchronization from
the same-queue semantics to guarantee a correct result.
Tested by making the ra_tex_resize function always fail (apart from the
initial FBO check). This required a few changes:
1. reset shaders on failed dispatch
2. reset cleanup binds on failed dispatch
3. fall back to initializing the struct image to 1x1 on failure
4. handle output_fbo_valid gracefully
This was sort of grating by default and made it really hard to actually
read e.g. text on top of a transparent background. I decided to approach
the problem from both directions, making the whites darker and the grays
lighter. This brings it closer to the dynamic range of e.g. the
wikipedia transparent svg preview.
Due to the plethora of historical baggage from different eras getting
confusing, I decided to simplify and unify the struct organization and
naming scheme.
Structs that got renamed:
1. fbodst -> ra_fbo (and moved to gpu/context.h)
2. fbotex -> removed (redundant after 2af2fa7a)
3. fbosurface -> surface
4. img_tex -> image
In addition to these structs being renamed, all of the names have been
made consistent. The new scheme is as follows:
struct image img;
struct ra_tex *tex;
struct ra_fbo fbo;
This also affects derived names, e.g. indirect_fbo -> indirect_tex.
Notably also, finish_pass_fbo -> finish_pass_tex and finish_pass_direct
-> finish_pass_fbo.
The new equivalent of fbotex_change() is called ra_tex_resize().
This commit (should) contain no logic changes, just renaming a bunch of
crap.
I've observed the garbage pixels in more scenarios. They also were never
really needed to begin with, originally being a discovered work-around
for bug that we fixed since then anyway. Doesn't really seem to even
help resizing, since the OpenGL drivers are all smart enough to pool
resources internally anyway.
Fixes#1814
Enabling double buffering fixed some graphical glitches when entering
fullscreen, but it also caused a fullscreen performance regression. We
decided that the glitches were preferable to the performance regression.
This reverts commit cee764849e4fe22b00fb3f31838a63906e2e0d54.
The code used ra_ctx_destroy even though ra_ctx_create was never called
(since it's just a dummy ctx), which led to a conflict of assumptions.
The proper fix is to only use ra_gl_ctx_uninit (mirroring the
ra_gl_ctx_init) and free the dummy ctx manually.
Fixes https://github.com/cmdrkotori/mpc-qt/issues/129
We want e.g. --opengl-shaders-append=foo to resolve to the new option,
all while printing an option name. --opengl-shader is a similar case.
These options are special, because they apply "actions" on actual
options by specifying a suffix. So the alias/deprecation handling has to
be part of resolving the actual option from prefix and suffix.
Turns out the option code apparently tries to directly talloc_free() the
allocated strings, instead of going through a tactx wrapper or
something. So we can't directly overwrite it. Do something else
instead..
Almost as fast as the old code, but more general. Notably, glslang
doesn't support nested arrays.
(cf. https://github.com/KhronosGroup/glslang/issues/1057)
Also much cleaner code-wise, so I think I'll keep it even if glslang
implements array_of_arrays.
This never really made sense since the BT.1886 changes. It should get
*brighter* for bright rooms, not darker for dark rooms. Picked some new
values that seemed reasonable-ish.
This causes a performance regression on 10.11 and newer, but the single
buffered method was broken and could cause partially rendered frames to
be presented to the screen.
This reverts 9f30cd8292b4b7bfe5d7db29fe31a07cc76dec2c and
e543853a7ff0ab4dcd4ccaf06c448013fd41c03a.
This is done in several steps:
1. refactor MPGLContext -> struct ra_ctx
2. move GL-specific stuff in vo_opengl into opengl/context.c
3. generalize context creation to support other APIs, and add --gpu-api
4. rename all of the --opengl- options that are no longer opengl-specific
5. move all of the stuff from opengl/* that isn't GL-specific into gpu/
(note: opengl/gl_utils.h became opengl/utils.h)
6. rename vo_opengl to vo_gpu
7. to handle window screenshots, the short-term approach was to just add
it to ra_swchain_fns. Long term (and for vulkan) this has to be moved to
ra itself (and vo_gpu altered to compensate), but this was a stop-gap
measure to prevent this commit from getting too big
8. move ra->fns->flush to ra_gl_ctx instead
9. some other minor changes that I've probably already forgotten
Note: This is one half of a major refactor, the other half of which is
provided by rossy's following commit. This commit enables support for
all linux platforms, while his version enables support for all non-linux
platforms.
Note 2: vo_opengl_cb.c also re-uses ra_gl_ctx so it benefits from the
--opengl- options like --opengl-early-flush, --opengl-finish etc. Should
be a strict superset of the old functionality.
Disclaimer: Since I have no way of compiling mpv on all platforms, some
of these ports were done blindly. Specifically, the blind ports included
context_mali_fbdev.c and context_rpi.c. Since they're both based on
egl_helpers, the port should have gone smoothly without any major
changes required. But if somebody complains about a compile error on
those platforms (assuming anybody actually uses them), you know where to
complain.
This overrides the use of GLX_SGI_swap_control, because apparently
GLX_SGI_swap_control doesn't support SwapInterval(0), but the
GLX_MESA_swap_interval does.
Of course, everybody except mesa just accepts SwapInterval(0) even for
GLX_SGI_swap_control, but mesa needs to be the special snowflake here
and reject it, forcing us to load their stupid named extension instead.
Meanwhile khronos has done nothing except spit out GLX_EXT_swap_control
(not to be confused with GL_EXT_swap_control, which is exported by
WGL_EXT_swap_control), that doesn't fix the problem because mesa doesn't
implement it anyway.
What a fucking mess.
Even if the contents are entirely zero. In the current code, these
entries were left uninitialized. (Which always worked for nvidia - but
randomly blew up for AMD)
This is simultaneously generalized into two directions:
1. Support more sc_uniform types (needed for SC_UNIFORM_TYPE_PUSHC)
2. Support more flexible packing (needed for both PUSHC and ra_d3d11)
This is around 512 kB, which is just way too much. Heap-allocate it
instead. Also cut down the max pass count to 64, since 128 was
unrealistically high even for vo_opengl.
Instead of relying on power-of-two buffer sizes and unsigned overflow,
make this code more robust (and also cleaner).
Why can't C get a real modulo operator?
This was there even before the refactor, but the refactor exposed the
bug. I hate C's useless fucking modulo operator so much. I've gotten hit
by this exact bug way too many times.
Since the addition of UBOs, the assumption that the uniform index
corresponds to the pass->params.inputs index is no longer true. Also,
there's no reason it would even need this - since the `input` is also
available directly in sc_uniform.
I have no idea how I've been using this code for as long as I have
without any segfaults until earlier today.
This was needlessly complicated and prone to breakage, because even the
references to the ring buffer could end up getting invalidated and
containing garbage data on e.g. shader cache flush. For much the same
reason why we can't keep around the *timer_pool, we're also forced to
hard-copy the entire sample buffer per pass per frame.
Not a huge deal, though. This is, what, a few kB per frame? We have more
pressing CPU performance concerns anyway.
Also simplified/fixed some other code.
This clearly highlights all out-of-gamut/clipped pixels. (Either too
bright or too saturated)
Has some (documented) caveats. Also make TONE_MAPPING_CLIP stop actually
clamping the value range (it's unnecessary and breaks this feature).
Redefining texture1D / texture3D seems to be illegal, they are already
built-in macros or something. So just use tex1D and tex3D instead.
Additionally, GL_KHR_vulkan_glsl requires using explicit vertex
locations and bindings, so make some changes to facilitate this. (It
also requires explicitly setting location=0 for the color attachment
output)
Vulkan compat. rgb16 doesn't exist on hardware anyway, might as well
just generate the 3DLUT against rgba16 as well. We've decided this is
the simplest way to do vulkan compatibility: just make sure we never
actually need 3-component textures.
This is mostly done so we can support using textures with more
components than the scaler LUTs have entries. But while we're at it,
also change the way the weights are packed so that they're always
sequential with no gaps. This allows us to simplify
pass_sample_separated_get_weights as well.
Mouse wheel bindings have always been a cause of user confusion.
Previously, on Wayland and macOS, precise touchpads would generate AXIS
keycodes and notched mouse wheels would generate mouse button keycodes.
On Windows, both types of device would generate AXIS keycodes and on
X11, both types of device would generate mouse button keycodes. This
made it pretty difficult for users to modify their mouse-wheel bindings,
since it differed between platforms and in some cases, between devices.
To make it more confusing, the keycodes used on Windows were changed in
18a45a42d524 without a deprecation period or adequate communication to
users.
This change aims to make mouse wheel binds less confusing. Both the
mouse button and AXIS keycodes are now deprecated aliases of the new
WHEEL keycodes. This will technically break input configs on Wayland and
macOS that assign different commands to precise and non-precise scroll
events, but this is probably uncommon (if anyone does it at all) and I
think it's a fair tradeoff for finally fixing mouse wheel-related
confusion on other platforms.
It seems like the Cocoa backend used to return the same mpv keycodes for
mouse back/forward as it did for scrolling up and down. Fix this by
explicitly mapping all Cocoa button numbers to the right mpv keycodes.
mpv's mouse button numbering is based on X11 button numbering, which
allows for an arbitrary number of buttons and includes mouse wheel input
as buttons 3-6. This button numbering was used throughout the codebase
and exposed in input.conf, and it was difficult to remember which
physical button each number actually referred to and which referred to
the scroll wheel.
In practice, PC mice only have between two and five buttons and one or
two scroll wheel axes, which are more or less in the same location and
have more or less the same function. This allows us to use names to
refer to the buttons instead of numbers, which makes input.conf syntax a
lot easier to remember. It also makes the syntax robust to changes in
mpv's underlying numbering. The old MOUSE_BTNx names are still
understood as deprecated aliases of the named buttons.
This changes both the input.conf syntax and the MP_MOUSE_BTNx symbols in
the codebase, since I think both would benefit from using names over
numbers, especially since some platforms don't use X11 button numbering
and handle different mouse buttons in different windowing system events.
This also makes the names shorter, since otherwise they would be pretty
long, and it removes the high-numbered MOUSE_BTNx_DBL names, since they
weren't used.
Names are the same as used in Qt:
https://doc.qt.io/qt-5/qt.html#MouseButton-enum
If a VO-area option changes, gl_video_resize() is called
unconditionally. This function does something even if the size does not
change (at least it discards buffered frames for interpolation), which
can lead to stutter when you keep firing option change events during
playback.
Check for an actual resize, and if nothing changes, exit early.
Could cause a crash if anything called ra_get_imgfmt_desc(imgfmt=0). Let
it fail correctly. This can happen if a hwdec backend does not set
hw_subfmt correctly.
This also introduces RA_CAP_GLOBAL_UNIFORM. If this is not set, UBOs
*must* be used for non-bindings. Currently the cap is ignored though,
and the shader_cache *always* generates UBO-using code where it can.
Could be made an option in principle.
Only enabled for drivers new enough to support explicit UBO offsets,
just in case...
No change to performance, which is probably what we expect.
This no longer concerns the API user except in as much as the API user
probably wants to know whether or not PBOs are active, so keep around
the CAP field even though it's mostly useless now.
Both vulkan and opengl distinguish between rendering to an image and
using an image as a storage attachment. So make this an explicit
capability instead of lumping it in with render_dst. (That way we could
support, for example, using an image as a storage attachment without
requiring a framebuffer)
The real reason for this change is that you can directly use the output
FBO as a storage attachment on vulkan but you can't on opengl, which
makes this param structly separate from render_dst.
I don't like the feeling of "reusing" the int binding for this. It
feels... wrong, somehow. I'd prefer to use an explicit "offset" field.
(Plus, I might re-use this for uniform buffers or something)
YMMV
I really wouldn't care much about this, but some parts of the core code
are under HAVE_GPL, so there's some need to get rid of it. Simply turn
the video equalizer from its current fine-grained handling with vf/vo
fallbacks into global options. This makes updating them much simpler.
This removes any possibility of applying video equalizers in filters,
which affects vf_scale, and the previously removed vf_eq. Not a big
loss, since the preferred VOs have this builtin.
Remove video equalizer handling from vo_direct3d, vo_sdl, vo_vaapi, and
vo_xv. I'm not going to waste my time on these legacy VOs.
vo.eq_opts_cache exists _only_ to send a VOCTRL_SET_EQUALIZER, which
exists _only_ to trigger a redraw. This seems silly, but for now I feel
like this is less of a pain. The rest of the equalizer using code is
self-updating.
See commit 96b906a51d5 for how some video equalizer code was GPL only.
Some command line option names and ranges can probably be traced back to
a GPL only committer, but we don't consider these copyrightable.
So far, we had a thread-safe way to read options, but no option update
notification mechanism. Everything was funneled though the main thread's
central mp_option_change_callback() function. For example, if the
panscan options were changed, the function called vo_control() with
VOCTRL_SET_PANSCAN to manually notify the VO thread of updates. This
worked, but's pretty inconvenient. Most of these problems come from the
fact that MPlayer was written as a single-threaded program.
This commit works towards a more flexible mechanism. It adds an update
callback to m_config_cache (the thing that is already used for
thread-safe access of global options).
This alone would still be rather inconvenient, at least in context of
VOs. Add another mechanism on top of it that uses mp_dispatch_queue, and
takes care of some annoying synchronization issues. We extend
mp_dispatch_queue itself to make this easier and slightly more
efficient.
As a first application, use this to reimplement certain VO scaling and
renderer options. The update_opts() function translates these to the
"old" VOCTRLs, though.
An annoyingly subtle issue is that m_config_cache's destructor now
releases pending notifications, and must be released before the
associated dispatch queue. Otherwise, it could happen that option
updates during e.g. VO destruction queue or run stale entries, which is
not expected.
Rather untested. The singly-linked list code in dispatch.c is probably
buggy, and I bet some aspects about synchronization are not entirely
sane.
Also refactors the usage of tex_upload to make ra_tex_upload_pbo a
RA-internal thing again.
ra_buf_pool has the main advantage of being dynamically sized depending
on buf_poll, so for OpenGL we'll end up only using one buffer (when not
persistently mapping) - while for vulkan we'll use as many as necessary,
which depends on the swapchain depth anyway.
This broke screensaver/powersave inhibition with at least KDE and
LXDE. This is a release blocker.
Since fdo, KDE and GNOME idiots seem to be unable to reach
a consensus on a simple protocol, this seems unlikely to get
fixed upstream this year, so revert this change.
Fixes#4752.
Breaks #4706 but I don’t give a damn.
This reverts commit 3f75b3c3439241c209349908fa190c0382e44f05.
- tex_uploads args are moved to a struct
- the ability to directly upload texture data without going through a
buffer is made explicit
- the concept of buffer updates and buffer polling is made more explicit
and generalized to buf_update as well (not just mapped buffers)
- the ability to call tex_upload/buf_update on a tex/buf is made
explicit during tex/buf creation
- uploading from buffers now uses an explicit offset instead of
implicitly comparing *src against buf->data, because not all buffers
may actually be persistently mapped
- the initial_data = immutable requirement is dropped. (May be re-added
later for D3D11 if that ever becomes a thing)
This change helps the vulkan abstraction immensely and also helps move
common code (like the PBO pooling) out of ra_gl and into the
opengl/utils.c
This also technically has the side-benefit / side-constraint of using
PBOs for OSD texture uploads as well, which actually seems to help
performance on machines where --opengl-pbo is faster than the naive code
path. Because of this, I decided to hook up the OSD code to the
opengl-pbo option as well.
One drawback of this refactor is that the GL_STREAM_COPY hack for
texture uploads "got lost", but I think I'm happy with that going away
anyway since DR almost fully deprecates it, and it's not the "right
thing" anyway - but instead an nvidia-only hack to make this stuff work
somewhat better on NUMA systems with discrete GPUs.
Another change is that due to the way fencing works with ra_buf (we get
one fence per ra_buf per upload) we have to use multiple ra_bufs instead
of offsets into a shared buffer. But for OpenGL this is probably better
anyway. It's possible that in future, we could support having
independent “buffer slices” (each with their own fence/sync object), but
this would be an optimization more than anything. I also think that we
could address the underlying problem (memory closeness) differently by
making the ra_vk memory allocator smart enough to chunk together
allocations under the hood.
Instead of merging it into render_dst. This is better for vulkan,
because blitting in vulkan both does not require a FBO *and* requires a
different image layout.
Also less "hacky" for OpenGL, since now the weird blit=FBO requirement
is an implementation detail of ra_gl
This extracts non-ANGLE specific code to d3d11_helpers.c, which is
modeled after egl_helpers.c. Currently the only consumer is
context_angle.c, but in future this may allow the D3D11 device and
swapchain creation logic to be reused in other backends.
Also includes small improvements to D3D11 device creation. It is now
possible to create feature level 11_1 devices (though ANGLE does not
support these,) and BGRA swapchains, which might be slightly more
efficient than ARGB, since its the same format used by the compositor.
This is for legacy GL: if VAOs are not available, the helper has to
specify vertex attributes again on every rendering. gl_vao_init() keeps
the vertex array for this purpose. Unfortunately, a temporary argument
was passed to the function, instead of the permanent copy.
Also, it didn't use num_entries (instead expected the array being
terminated by a {0} entry). Fix that source code indentation too.
In commit c6fafbffaca1 we accidentally set the logical texture size to
the cropped video size, which is not correct. This caused rendering
artifacts in some cases.
Use the video surfaces size instead. Since the current mp_image_params
contains the cropped size only, wrapper texture creation has to be moved
to the _map function. Move the same code for the mixer case (strictly
speaking this is not needed, but seems more symmetric).
(Also there is no need to clear gl_textures on uninit - leftover from
the old hwdec mapper API. So we just drop that part.)
Fixes#4760.
Retrieve the depth for each component and internal texture format
separately. Only for 8 bit per component textures we assume that all
bits are used (or else we would in my opinion create too many probe
textures).
Assuming 8 bit components are always correct also fixes operation in
GLES3, where we assumed that each component had -1 bits depth, and this
all UNORM formats were considered unusable. On GLES, the function to
check the real bit depth is not available. Since GLES has no 16 bit
UNORM textures at all, except with the MPGL_CAP_EXT16 extension, just
drop the special condition for it. (Of course GLES still manages to
introduce a funny special case by allowing GL_LUMINANCE , but not
defining GL_TEXTURE_LUMINANCE_SIZE.)
Should fix#4749.
Runtime untested, because I get this:
[vo/rpi] Could not get DISPMANX objects.
This happened even when building older git versions, and on a RPI image
that hasn't changed in the recent years. I don't know how to make this
POS work again, so I guess if there's a bug in the new code, it will
remain broken.
This does two separate rather intrusive things:
1. Make the hwdec context (which does initialization, provides the
device to the decoder, and other basic state) and frame mapping
(getting textures from a mp_image) separate. This is more
flexible, and you could map multiple images at once. It will
help removing some hwdec special-casing from video.c.
2. Switch all hwdec API use to ra. Of course all code is still
GL specific, but in theory it would be possible to support other
backends. The most important change is that the hwdec interop
returns ra objects, instead of anything GL specific. This removes
the last dependency on GL-specific header files from video.c.
I'm mixing these separate changes because both requires essentially
rewriting all the glue code, so better do them at once. For the same
reason, this change isn't done incrementally.
hwdec_ios.m is untested, since I can't test it. Apart from superficial
mistakes, this also requires dealing with Apple's texture format
fuckups: they force you to use GL_LUMINANCE[_ALPHA] instead of GL_RED
and GL_RG. We also need to report the correct format via ra_tex to
the renderer, which is done by find_la_variant(). It's unknown whether
this works correctly.
hwdec_rpi.c as well as vo_rpi.c are still broken. (I need to pull my
RPI out of a dusty pile of devices and cables, so, later.)
Less flexible than GL_TIMESTAMP but supported by more platforms. This
will mean that nested queries have to be detected and silently omitted,
but oh well. Not much use for them anyway.
Fixes#4721.
It's an ancient X11 protocol extension that apparently nobody uses
anymore (desktop environments in particular have replaced it with
equally bad protocols that require tons of dependencies). Users keep
complaining about it being a required dependency.
The impact is likely minimal to none.
Fixes#4706 and other annoying people.
Generic description of pixel formats is hard. In this case, the Apple
special format for packed YUV could have been interpreted as a RGB
format with funny packing.
Move multiple GL-specific things from the renderer to other places like
vo_opengl.c, vo_opengl_cb.c, and ra_gl.c.
The vp_w/vp_h parameters to gl_video_resize() make no sense anymore, and
are implicitly part of struct fbodst.
Checking the main framebuffer depth is moved to vo_opengl.c. For
vo_opengl_cb.c it always assumes 8. The API user now has to override
this manually. The previous heuristic didn't make much sense anyway.
The only remaining dependency on GL is the hwdec stuff, which is harder
to change.
Completely unnecessary, we can just update the uniforms immediately
after creating the program. In theory, for GLSL 4.20+, we could even
skip this, but oh well.
The vp_w/vp_h variables and parameters were not really used anymore
(they were redundant with ra_tex w/h) - but vp_h was still used to
identify whether rendering should be done mirrored.
Simplify this by adding a fbodst struct (some bad naming), which
contains the render target texture, and some parameters how it should be
rendered to (for now only flipping). It would not be appropriate to make
this a member of ra_tex, so it's a separate struct.
Introduces a weird regression for the first frame rendered after
interpolation is toggled at runtime, but seems to work otherwise. This
is possibly due to the change that blit() now mirrors, instead of just
copying. (This is also why ra_fns.blit is changed.)
Fixes#4719.
