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.
|
|
|
|
|
| |
There's no reason to be needlessly wasteful with our binding points
here. Just add a CAP for it.

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

Shouldn't make a difference for OpenGL (even with the weird duplication
of these functions removed). Might be useful for the WIP vulkan backend.

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.

- 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
|

These are no longer valid anyway, and the code doesn't use them.

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.)
|
|
|
|
| |
Probably explains quality issues in some cases.
|
|
|
|
|
| |
Just remove one callback, and fold the functionality into the other one.
RPI will still not compile, so the hwdec_rpi.c changes are untested.
|
|
|
|
|
| |
As seen in hwdec_ios.m, it insists on using the legacy luminance alpha
formats for mapped textures.
|
|
|
|

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.

This also fixes a double free in vo_opengl_cb.c.

Also fix a typo in ra_gl.c. Too greedy for a separate commit.

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.

Don't leak the buffer if glGetProgramBinary() fails.
|
|
|

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.
|

Also fixes an issue where 1 << 5 was used twice, probably because of the

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.

This allows us to integrate PBOs and SSBOs into the same abstraction,
with the potential to easily add UBOs if the need arises.

When using dumb mode, we can actually redraw a frame without uploading
it. Marking this as fresh as well results in unpredictable pass
behavior, which is confusing and makes debugging harder. So mark it as a
redraw instead, in that case.
|
|
|
|
|
|

Since the GL *gl is no longer needed for the timers, we can get rid of
the sc->gl dependency. This requires moving a utility function (which is
not GL-specific anyway) out of gl_utils.h and into utils.h

In the past, this always measured the per-shader execution times of the
individual OSD parts, which was thrown off because the shader was reused
anyway. (And apparently recording the OSD shader execution times was
removed completely, probably because of them being so unrealiably
anyway)
Since ra_timer no longer has the restriction of not allowing timers to
run concurrently, we can just wrap the entire OSD block inside a single
osd_timer now, and record that. (Technically, this can still be off when
using --blend-subtitles=video/yes and showing a full-screen OSD at the
same time. Maybe this can be done better?)
|
|
|
|
|
|
|

In order to prevent code duplication and keep the ra abstraction as
small as possible, `ra` only implements the actual timer queries,
it does not do pooling/averaging of the results. This is instead moved
to a ra-neutral struct timer_pool in utils.c.

This code is pretty much for the sake of vo_opengl_cb API users. It
resets certain state that either the user or our code doesn't reset
correctly. This is somewhat outdated. With GL implicit state being
so awfully large, it seems more reasonable require that any code
restores the default state when returning to the caller. Some
exceptions are defined in opengl_cb.h.

Now all GL-specifics of shader compilation are abstracted through ra.
Of course we still have everything hardcoded to GLSL - that isn't going
to change.
Some things will probably change later - in particular, the way we pass
uniforms and textures to the shader. Currently, there is a confusing
mismatch between "primitive" uniforms like floats, and others like
textures.
Also, SSBOs are not abstracted yet.
|
|
|
|
|
|
|
|
| |
Instead of having a mutable ra_tex field (and the only one), move the
flag to struct ra, since we have only 2 tex_upload user calls anyway,
and both want the same PBO behavior. (At first I considered making it
a RA_TEX_UPLOAD_ flag, but why bother. PBOs are a terribly GL-specific
thing, so we can't expect a reasonable abstraction of it anyway.)
