Older OSX versions are missing some OpenGL 3 symbols, apparently. At
least there's some precedent in the headers. Just add the symbols
manually for now to fix OSX (on travis-ci) compilation.

Tested with MESA on software emulation. Seems to work well, although the
default FBO format in opengl-hq disables most interesting features. I
have no idea how well it will work on real hardware (or if it does at
all).
Unfortunately, some features, including playback of 10 bit video, are
not supported. Not sure what to do about this.
GLES 2 or 1 do not work.

Remove the readback stuff; it was a useless mess.
Don't test GL_R16 as FBO. The intention was to measure the effective
bitdepth of the texture, except that it was never actually done.
(There's also a OpenGL function which is supposed to retrieve the
bitdepth, but we don't use that either.)

Might be slightly more compatible too, and will make it work on GLES.

I'm hoping this is generally more compatible, and it works with GLES.
This probably has not much of an effect on desktop GL. It also switches
only the default format for --vo=opengl, not --vo=opengl-hq.
"-hq" already uses GL_RGBA16, though since it's a sized format, the
story is a bit different, and it won't work on GLES either.

Older GLSL dialects as well as GLES3 do not support the following things
in expressions:
- implicit conversions of integer constants to float
- arithmetic of float*vecN

Because of the icc-profile-auto option (which was added at a later
point), supporting this would probably be slightly messy: the ICC
profile can spontaneously update, and then it would overwrite the
previously set options.
Don't make icc-profile-auto fatal if unsupported. The "auto" indicates
that it will use whatever it finds, even if it's nothing.
Also add a warning; before this commit, it just refused to initialize
without explanation.
As a mostly unrelated cosmetic change, remove redundant parameters which
had no point anymore.
Probably fixes #1359 (or rather works it around by disallowing it).

Features not supported are disabled (although with a misleading error
message).

Obscure feature, and I've never heard of anyone using it.
The anaglyph effects can be reproduced with vf_stereo3d. The only thing
that can't be reproduced with it is "quadbuffer", which requires special
and expensive hardware.

Commit d38bc531 is incorrect: the 50ms queue-ahead value and the flip
queue offset have different functions. The latter is about calling
flip_page in advance, so the change attempted to show video frames 50ms
in advance on all VOs.
The change was for vo_opengl_cb, but that can be handled differently.

Can happen on Windows, I suppose.

It was missing an indentation in some cases.

In theory, vo_opengl supports operation without framebuffers. But this
has been broken for a while now (commit cc00b3ff is a contender). It
crashed because it unconditionally called gl->BindFramebuffer() (which
is NULL if framebuffers are missing).
Since this function is actually only called to set the default
framebuffer, the simplest way to deal with this is to provide a dummy
function, insteas of uglifying the code with additional if branches.

I think that's expected; mpv shouldn't draw anything while no video is
active. This doesn't blend transparently, though.
Also document the vo_opengl_cb thing.
|
|
|
|
|
| |
This mainly affects the black bars that are drawn if the window and
video aspect ratios mismatch.

This adds API to libmpv that lets host applications use the mpv opengl
renderer. This is a more flexible (and possibly more portable) option to
foreign window embedding (via --wid).
This assumes that methods like context sharing and multithreaded OpenGL
rendering are infeasible, and that a way is needed to integrate it with
an application that uses a single thread to render everything.
Add an example that does this with QtQuick/qml. The example is
relatively lazy, but still shows how relatively simple the integration
is. The FBO indirection could probably be avoided, but would require
more work (and would probably lead to worse QtQuick integration, because
it would have to ignore transformations like rotation).
Because this makes mpv directly use the host application's OpenGL
context, there is no platform specific code involved in mpv, except
for hw decoding interop.
main.qml is derived from some Qt example.
The following things are still missing:
- a way to do better video timing
- expose GL renderer options, allow changing them at runtime
- support for color equalizer controls
- support for screenshots

Doesn't leak unless we switch video tracks on and off while in fullscreen.

I guess most problems with it have been fixed.
It's still slower than necessary, though.

Not all filter sizes the shaders could handle were in the filter_sizes
list. The shader can handle any multiple of 4 (the sizes 2 and 6 are
special-cased to keep it simple).
Add all possible filter sizes, up to 64. 64 is ridiculously high anyway.
Most of the larger filter sizes are completely useless for upscaling,
but help with the fancy-downscaling option. (Although it would still be
more efficient to use cascaded scalers to handle downscaling better.)
I considered doing something less stupid than the hardcoded array, but
it seems this is still the simplest solution.

Before this commit, the convolution scaler shader functions were pre-
instantiated in the shader file. For every filter size, a corresponding
function (with the filter size as suffix) had to be present.
Change this, and make the C code emit the necessary bits.
This means the shader code is much reduced. (Although hopefully it
doesn't make shader compilation faster - it would require a really dumb
compiler if it spends its time on dead code.)
It also makes it more flexible, which is the main goal.
The DEF_SCALER0 stuff is needed because the C code writes the header of
the shader, at a point where scaler macros are not defined yet.

This was a microoptimization for small filters which need 4 or less
weights per sample point. When I originally wrote this code, using a 1D
texture seemed to give a slight speed gain, but now I couldn't measure
any difference.
Remove this to simplify the code.
|
|
|
|
|
|
|

There's not much of a reason to have the actual convolution code in a
separate function. Merging them actually simplifies the code a bit, and
gets rid of the repetitious macro invocations to define the functions
for each filter size.
There should be no changes in behavior or output.

Windows uses a heuristic to determine if a window should appear
fullscreen. If the active window's client area covers the whole screen,
the taskbar should move to the bottom of the Z-order, allowing the
window to show through.
Unfortunately, sometimes it doesn't work and the taskbar stays on top of
the "fullscreen" window. ITaskbarList2->MarkFullscreenWindow explicitly
tells the shell that a window wants to be fullscreen, so the taskbar is
always at the bottom of the Z-order while the marked window is active.
This might help with #999. Firefox also uses this interface to fix
fullscreen issues.

For better downscaling.
Maybe the list of filter sizes shouldn't be static...
|
|
|
|
|
|
|
|
|
|
|

This gives better results with fancy-downscaling. The issue here is that
fancy-downscalign "extends" the filter radius by some amount, which
requires using a larger filter size and shader. Then most of the filter
is "unused", but some filters still return non-0 coefficients, which
create heavy artifacts. Just clamp them off.
I'm not sure if this is the right solution, but at least it's better
than before.

Previously when using the bundle we used a custom bizarro thing to wait for
events. Just use `--idle` and greatly simplify the code.

Seems it's actually buggy, beyond the problem that large filter sizes
are required.

Also replace the weights calculations for 8/12/16 with the generic
weight function definition macro. (The weights 2/4/6 follow slightly
different rules.)

Instead go through our function loader.

This fixes the very annoying glitch where the black bars disappear for
a single frame when going fullscreen.

This wasn't done before because there was no advantage in "abstracting"
it. This changed, and putting this into its own files is better than
messing it into gl_common.c/h.

Same as with the previous commits.
In theory, vdpau/x11 GL interop doesn't assume GLX. It could use EGL as
well. But since it's always GLX in practice, so we're fine with this.
Remove the gl_hwdec.mpgl field - it's unused now.
|
|
|
|
| |
Same as with the VDA change.
|
|
|
|
|
|
|
|
|
| |
Basically, don't access the vo field.
There's also no reason anymore to access MPGLContext. We still need to
access loaded GL functions though, so add a field for that to gl_hwdec.
Untested.
|
|
|
|

Removes the dependency from the Cocoa backend in case we are not using
it but still wanna use VDA GL introp.

Always set the viewport on entry. The way the viewport is tracked is a
bit complicated in my opinion, and in fact it doesn't even reduce the
number of GL calls. Setting it on entry is actually redundant if video
covers the screen fully, because the handle_pass() unconditionally sets
it anyway, but avoiding it would complicate the cases gl->Clear() is
actually needed.
Add a fbo argument to gl_video_render_frame(). This allows you to render
into a FBO rather than the default framebuffer. It will be useful for
providing an API to render on an external GL context. (If that will
actually be added.)
