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 was required by vf_pp, which was just removed.
vf_dlopen has this stuff in its API. This API is considered stable, so
the related fields are not removed from it. But the fields are always 0
now, so there's no point in keeping the example program around.
vf_pullup.c did some extremely awkward passthrough of this information,
but didn't actually use it.

This is an ancient filter, and we assume it's not useful anymore.
If you really want this, it's still available in libavfilter (e.g. via
--vf=lavfi=[pp...]). The disadvantage is that mpv doesn't pass through
QP information to libavfilter. (This was probably the reason vf_pp still
was part of mpv - it was slightly easier to pass QP internally.)

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.)

Seems like a waste not to print this.
Anyone with enough technical knowledge to have use for the exact error
can map the number back to the GL symbol, so don't bother to convert it
to a symbol.

This is "better", although nobody seems to know how this API is supposed
to work at all.

fixes #1302

All of these are already the defaults.
One exception is glDepthMask(), which is enabled by default. But if the
framebuffer has no depth buffer anyway, it shouldn't make a difference.

libxkbcommon keysyms are the same as X11 keysyms (sans prefix),
so I simply copied the missing subsection from x11_common.c.

MS Windows doesn't allow windows larger than the screen, so we include
a hack to make the window smaller. This hack recenters the window (what
else would it do?).
It didn't account for the virtual offset of the current screen, and it
was reported that it forces the window to the first screen.
Should fix #1292.

I suspect this is what is happening in github issue #1265 (at least
partially).
If D3DFMT_A8 is not available, fall back to RGBA. This is less efficient
in general, so we normally want to avoid it.

...because everything is terrible.
strerror() is not documented as having to be thread-safe by POSIX and
C11. (Which is pretty much bullshit, because both mandate threads and
some form of thread-local storage - so there's no excuse why
implementation couldn't implement this in a thread-safe way. Especially
with C11 this is ridiculous, because there is no way to use threads and
convert error numbers to strings at the same time!)
Since we heavily use threads now, we should avoid unsafe functions like
strerror().
strerror_r() is in POSIX, but GNU/glibc deliberately fucks it up and
gives the function different semantics than the POSIX one. It's a bit of
work to convince this piece of shit to expose the POSIX standard
function, and not the messed up GNU one.
strerror_l() is also in POSIX, but only since the 2008 standard, and
thus is not widespread.
The solution is using avlibc (libavutil, by its official name), which
handles the unportable details for us, mostly. We avoid some pain.

Always create the context in mpgl_init(), instead of doing it when
mpgl_config_window() is called the first time. This is a small step
towards cleaning up the GL backend interface, and adding other things
like perhaps GLES support, or a callback-driven backend for libmpv.

I didn't quite understand this comment after looking at the code again
months later, so I reworded it for better clarity.

Sampling from the source texture and scaling must always be done
separately in this mode.
Fix suggested by haasn.
Still looks a bit wrong, though.

But seriously, don't use --wid=0, don't use vo_xv, and _especially_
don't use vo_x11.

This way, no surfaces are in use when uninitializing the hw decoders,
which might help with -copy hw decoders (normal hw decoding is not
affected).

This sub-option was turned into a flag when the sub-option parser was
changed to the generic one (probably accidentally). Turn it into a
proper choice-option.
Also, adjust what the options do. Though none of this probably makes
much sense; the default should work, and if it doesn't, the GPU/driver
is probably beyond help.
