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

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).
Following the previous commit, we can just set gnu_symbol_visibility to
'hidden' to hide everything except for the symbols we explictly want to
export. This should work on gcc, clang, and msvc.
In mpv, the only symbols we want to export are the functions from the
client API. This is accomplised using a specific .def whitelist, but the
main compilers people use (gcc or clang) like these attributes since it
allows for further optimizations. MSVC also allegedly supports this as
well (untested of course), so use __declspec for tht case.
This almost perfectly recreates the semantics of --vo=gpu, i.e.:
- still frames are never interpolated
- non-repeated frames bypass single frame cache
The only difference is that libplacebo doesn't do a cache/blit on the
full output image, but rather it re-runs the last rendering step. This
has some advantages and some drawbacks. The most notable advantage is
that it also allows re-using the image contents when the only thing that
changes is the OSD (whereas `--vo=gpu` would force a full re-render for
that). The most notable drawback is that it also implies going through
the dithering and output LUT logic on redraws. All in all, I think this
is a pretty good trade-off in favor of `--vo=gpu-next`.
Fully fixes the last remaining performance difference in #9430.
GLX_CONTEXT_PROFILE_MASK_ARB and related constants are provided by
GLX_ARB_create_context_profile but the check was for _create_context.
The former implies the latter (which we also need) so just replace
the checked extension.
It abstracts EGL 1.5, extension checks and other inconsistencies away.
This can be used in context code as the (preferred) alternative to
eglCreateWindowSurface().
Using a simple substring match for extension checks is considered bad practice
because it's incorrect when one extension is a prefix of another's name.
This will almost surely not make a difference in practice but do it for correctness anyway.
Although there are no known problems with this, using the helper should
be more portable. It will also prefer EGL 1.5's eglGetPlatformDisplay
over eglGetPlatformDisplayEXT if available.
The original implementation had some errors with regards to android. Add
a couple of missing files, add the android library, fix the aviocontext
bytes_read check, fix egl-android, and rearrange/tidy up the vulkan
handling.
While the basic Vulkan Display context can theoretically drive the
display without the involvement of any non-Vulkan code, that prevents
us from using VAAPI acceleration. When initialising VAAPI without a
window system, we need to provide it with an opened DRM render fd
corresponding to the device to use.
In the context of using VK_KHR_display, that means we need to identify
which DRM device matches the selected Vulkan device, and then open its
render fd and set the necessary state that VAAPI expects to find.
With that done, the normal VAAPI<->Vulkan interop can kick in and we
get working acceleration
A few custom targets had some less than optimal names which created some
misleading "Generating custom-target-name with a custom command"
messages. Change those to be more descriptive/correct. In a few other
places, some checks were being done that could easily be
skipped/ignored in certain cases (like checking for windows-related
headers when gl-win32 isn't true). Also rearrange that to be smarter.
Finally, print some extra libplacebo messages for enabling/disabling
vo_gpu_next.
This test fails because the compiler object does not have -Wformat when
it tries this flag. To fix this this, we have to pass both -Wformat and
-Werror=format-security at the same time during the test. This requires
us to use has_multi_arguments so this flag needs to be pulled out of
this array and tested separately.
