Shaderc has been shipping .pc files for almost three years and we all
know of the advantages. If this turns out to be problematic the old checks
can be re-added but I'd like to avoid doing this preemptively.
During execve() ignored and blocked signals carry over to the child
process, though apparently for SIGCHLD (which the bug report was about)
this is implementation-defined.
fixes#9613
We've been assuming that maximum number of compute group threads is
never less than the 1024 defined by the desktop GL spec. Given that we
haven't had working compute shaders for GLES and I guess the Vulkan
spec defines at least as high a value, we've gotten away with it so
far.
But we should really look the value up and respect it.
This is only needed on Android and supposed to handle a context
resize without reconfiguring the image parameters. reconfig()
already does exactly this so plug it in there.
Not all deprecated symbols were removed. Only three events were removed for now
since these are not used internally.
This bumps the library version to 2.0.
Simply returning out of this function leaks avpkt, need to always "goto
done".
Rewrite the logic a bit to make it more clear what's going on (IMO).
Fixes#9593
It's supposed to work with GLES >= 3.1 but we had all sorts of bad
assumptions in our version handling, and then our compute shaders
turn out not to be GLSL-ES compliant.
This change contains some necessary, but insufficient, tweaks to the
shaders. Perhaps we'll make it actually work some day.
Some of the extension declarations did not include the ES version where
they became core functionality, and in some of these cases, there was
never actually an ES extension - it first appeared in core. We also had
a number of buggy version checks where ES versions were compared
against required desktop GL versions.
nvidia follow the OpenGL spec very strictly, with two particular
consequences:
* They will give you the exact context version that you ask for,
rather than the highest possible version that meets your request.
* They will hide extensions that the specs say require a higher
version than you request, even if it's technically possible to
provide the extension at lower versions.
In our case, we really want a variety of extensions, particularly
compute shaders that are only available in 4.2 or higher. That means
that we must explicitly include a high enough version in our list of
versions to check for us to be able to get a 'good' enough context.
As for which version? We restore the 4.4 version that we had in the
old version selection logic. This is the highest version we ever asked
for, and we have separate logic that clamps the GLSL version to 4.4,
so anything newer wouldn't make a difference.
Since libavcodec major version 59, the requested "ass" format became
the default as the old timing-included format was disabled starting
with that version. Additionally, this option by itself has since
been deprecated as it no longer serves any purpose.

`plane_data_from_imgfmt` doesn't zero-initialize the struct, so this
contained invalid values for e.g. `row_stride`, causing formats to
*randomly* fail. (Especially any formats with specific alignment
requirements)
Might fix#9424 and #9425.
This is a workaround for nvidia proprietary drivers. The authors of
those drivers interpret the spec such that eglMakeCurrent will not
reconfigure the read and draw buffers. Thus windows wont display
anything drawn by opengl. nvidia authors refer to
https://www.khronos.org/registry/EGL/extensions/KHR/EGL_KHR_no_config_context.txt
specifically Issues 2/3 which reference eglMakeCurrent.
On mesa this is a non-issue and the read/draw targets are assigned with
eglMakeCurrent.
The context must be made current in order to query OpenGL strings. An
earlier proposal to create the wayland window surface similarly to X11
during init was deemed inappropriate so instead we manually set the
targets once we have created a window surface.
Allow --keep-open=always to work with --loop-playlist, where
before this patch it would work only on the last playthrough of the
playlist. This patch allows it to work on all playthroughs.
Fixes#9470.
Somewhat annoying but still relatively straightforward. There are
several ways to approach this, but I settled on reusing the pl_queue as
a cheap way to get access to the currently mapped frame. This saves us
from having to process `vo_frame` at all, and also avoids any overhead
from re-uploading the same frame twice.
(However maybe there's some circumstance in which `vo_frame` needs to be
queried/updated first, to get a screenshot of the correct frame? I'm not
sure.)
I also had the option of going with either pl_render_image() on the
extract pl_frame, or just calling pl_render_image_mix directly on it. I
went for the latter, because in the optimal case, this allows the
rendered frame to be directly retrieved from the cache, actually
entirely avoiding any sort of recompute overhead. This makes e.g. ctrl+s
during playback essentially free. (Except for the download cost,
obviously)
It would be even neater if we could make this VOCTRL asynchronous and
thereby leverage libplacebo's asynchronous download capabilities. But oh
well. That will have to wait for a sufficiently rainy day.
Closes#9388
20c4036daa switched to using symbol
visibility attributes for mpv client api functions (for the meson build
at least). Unfortunately mpv_client_api_version was mistakenly missed.
We need to export this function as well. Fixes#9531.
As noticed in #9526, apparently there's some case in which DR buffers
get corrupted. Add an explicit sentinel check to try and figure out
which cases these are.
The initial iconv dependency worked everywhere but was broken on
freebsd. This was fixed in 0.60.2 but the fix accidentally broke mingw
(ouch; kind of my fault for not double checking). There's another PR to
fix this but that won't land until 0.60.3 so for the meantime just
if/else this (both freebsd and windows work with the system method)
until we want to bump the meson version (probably not for a while since
opensuse tumbleweed is weirdly slow).
Previously OSD was always displayed on {ch,pl}_{next,prev} left-click,
and seekbar-hover-chapter was always enabled and with fixed format.
Now it can be controlled with:
- chapters_osd, playlist_osd: yes/no (only affects left-click).
- chapter_fmt: lua string.format template, or "no" to disable.
Fixes#4675
This commit sucks bad, but everything else is worse is other ways.
Basically, the current vblank waiting time in the vo_wayland_wait_frame
function (calculated very carefully using presentation statistics) is
randomly too short. Some compositors are quite variable when they
actually return callback so our timeout expires too quickly and throws
everything off. The fix? Add an arbitrary 5% to the vblank value and
pray that nothing gets off that much. Why did they have to make
swapinterval 1/fifo mode indefinitely block? Fixes#9504.
Better to avoid any wonky calculations on startup with garbage values.
The others end up being derived from last_ust/last_msc. refresh_interval
is referenced exactly once and could, in theory, result in some terribly
erroneous vblank time.
A read can be prepared on the wayland display FD that is never actually
read. This occurs when events are triggered on other FDs in the fd set.
This change cancels a prepared read if poll reported no events for it.
This fixes some hangs due to how nvidia's EGL implementation polls on
the wayland fd unlike mesa implementations. It is based on nvidia's
proposed fix for qt's similar message pump in
https://codereview.qt-project.org/c/qt/qtwayland/+/373473

This is done to avoid cluttering vo_gpu_next.c with more ifdeffery and context-specific code
when additional backends are added in the near future.
Eventually gpu_ctx is intended to take the place of ra_ctx to further separate gpu and gpu_next.
This case was added in 662c793a55
for use in vo_gpu_next as a visibility test before rendering a frame.
The OpenGL context doesn't have this so it just returns true.
This is needed when the color system is not explicitly tagged, but
instead needs to be inferred by the VO.
Note that there exists the function mp_image_params_guess_csp for this
sort of stuff, but it contains a lot of baggage that I don't want to
replicate, in order to move as much of this logic into pl_renderer as
possible, and therefore also give it the best chance of knowing what
shortcuts it can and can't take.
Fixes the other half of https://github.com/mpv-player/mpv/issues/9499
Adding vsync_offset to the pts in pl_queue_update actually messes up
frame timings if one isn't using interpolation. The easiest way to see
this is to have the monitor's refresh rate at an integer multiple of a
video during a panning shot (classic case). There will be very visible
judder/stutter in this case that does not happen in vo_gpu. The cause of
this is the addition of the extra vsync_offset. Just match the semantics
of vo_gpu where this is only used when interpolating.
This possibility actually existed for years. The wayland protocol is
asynchronous and there's no restriction on when a compositor can send a
surface enter event. In mpv's case, the surface enter event is used to
set some vital things regarded geometry/scaling etc. However, this
implictly assumes that wl->current_output is actually initialized. The
vast majority of the time, vo_wayland_reconfig will happen first which
is where wl->current_output is, and should, be created. There's no
rule/law that the ordering of events will always occur in this order.
Plasma with certain auto-profile conditions can send the surface enter
event before mpv does its initial reconfig. That segfaults of course.
Just add a check to make sure we have wl->current_output here and return
if we don't. This assumes that the compositor will send us another
surface enterance event when mpv actually does the initial surface
commit and roundtrip request later. Wayland logs indicate this does
happen. Fixes#9492.
It was never implemented before but it's trivial. As an aside, touch
events currently don't support modifiers either (is this a thing?). Well
if someone complains that can be done later. Fixes#9490.
The audio rewrite in d27ad96542 originally
broke this ao. However, 0ac724f002 fixed
and the documentation was never updated to reflect that. OpenAL has
worked fine for a while not. Just remove this sentence.
Even when not display synced. Prevents redraw overhead for refreshes
while paused.
Also make the logic slightly clearer to follow (since it's inverted).
