Add xoshiro as a PRNG implementation instead of relying
on srand() and rand() from the C standard library. This,
in particular, lets us avoid platform-defined behavior with
respect to threading.
Since the previous commit introduced the notion of a features dictionary
that conveniently tells us whether or not to use a feature in a simple
yes/no, we can make use of this everywhere in the build. Instead of
doing something like 'if foo.()', change it to 'if feature['foo']
instead. This enforces a consistent standard instead of having a lot of
different possible combinations of booleans that may or may not do
something.
mpv has a ton of defines that are generated during building. Previously,
the meson build just had this as a big giant wall of text that manually
set each one but we can do this smarter. Instead, change the "features"
object to a dictionary and have it hold the name of the feature and its
value (true/false on whether it is enabled). Then at the end, just loop
through it and reformat the name of the feature so it becomes
HAVE_FEATURE. A side effect of this is that a lot of extra defines are
generated that aren't actually used in the code, but the waf build
worked like this for years anyway. A nice result of this is that the use
of foo['use'] internally can be completely eliminated and replaced with
feature['foo'] instead when needed.
The build was a bit overzealous with using dictionaries. These are fine
for when the feature checking is more complicated, but there's no point
in having them for the simplier things. This also eliminates the usage
of the 'name' key completely.
ae768a1e14 forgot to bump the required
libdrm version however Debian 11 just barely misses the requirement,
which is a good reason not to require it unconditionally anyway.
In the confusing landscape of hardware video decoding APIs, we have had
a long standing support gap for the v4l2 based APIs implemented for the
various SoCs from Rockship, Amlogic, Allwinner, etc. While VAAPI is the
defacto default for desktop GPUs, the developers who work on these SoCs
(who are not the vendors!) have preferred to implement kernel APIs
rather than maintain a userspace driver as VAAPI would require.
While there are two v4l2 APIs (m2m and requests), and multiple forks of
ffmpeg where support for those APIs languishes without reaching
upstream, we can at least say that these APIs export frames as DRMPrime
dmabufs, and that they use the ffmpeg drm hwcontext.
With those two constants, it is possible for us to write a
hwdec-interop without worrying about the mess underneath - for the most
part.
Accordingly, this change implements a hwdec-interop for any decoder
that produces frames as DRMPrime dmabufs. The bulk of the heavy
lifting is done by the dmabuf interop code we already had from
supporting vaapi, and which I refactored for reusability in a previous
set of changes.
When we combine that with the fact that we can't probe for supported
formats, the new code in this change is pretty simple.
This change also includes the hwcontext_fns that are required for us to
be able to configure the hwcontext used by `hwdec=drm-copy`. This is
technically unrelated, but it seemed a good time to fill this gap.
From a testing perspective, I have directly tested on a RockPRO64,
while others have tested with different flavours of Rockchip and on
Amlogic, providing m2m coverage.
I have some other SoCs that I need to spin up to test with, but I don't
expect big surprises, and when we inevitably need to account for new
special cases down the line, we can do so - we won't be able to support
every possible configuration blindly.
Annoyingly, libva and libdrm use different structs to describe dmabufs
and if we are going to support drmprime, we must pick one format and do
some shuffling in the other case.
I've decided to use AVDRMFrameDescriptor as our internal format as this
removes the libva dependency from dmabuf_interop. That means that the
future drmprime hwdec will be able to populate it directly and the
existing hwdec_vaapi needs to copy the struct members around, but
that's cheap and not a concern.
This is the first in a series of changes that will introduce a drmprime
hwdec. As our vaapi hwdec is based around exporting surfaces as
drmprime dmabufs, we've actually got a lot of useful code already in
place in the GL/PL interops. I'm going to reorganise and adjust this
code to make the interops usable with the new hwdec as well.
The first step is to rename the files and functions. There are no
functional or other changes here. They will come next.
The meson build does a lot of checks and if you aren't familiar with the
internals of the meson.build, it may not be clear what is actually
enabled and what isn't. It turns out that meson has a handy function,
summary, exactly for this. This just prints a pretty summary of some
notable features in the build. It's not meant to be a comprehensive
list, but rather just what users are likely to care the most about (i.e.
x11, vulkan, etc.)
Immediately after this, d3d11 is defined again and the rest of the
meson.build uses that. Probably, this dictionary was from the original
meson PR and removing it was forgotten at some point while stuff was
being rewritten.
This builds off of present_sync which was introduced in a previous
commit to support xorg's present extension in all of the X11 backends
(sans vdpau) in mpv. It turns out there is an Xpresent library that
integrates the xorg present extention with Xlib (which barely anyone
seems to use), so this can be added without too much trouble. The
workflow is to first setup the event by telling Xorg we would like to
receive PresentCompleteNotify (there are others in the extension but
this is the only one we really care about). After that, just call
XPresentNotifyMSC after every buffer swap with a target_msc of 0. Xorg
then returns the last presentation through its usual event loop and we
go ahead and use that information to update mpv's values for vsync
timing purposes. One theoretical weakness of this approach is that the
present event is put on the same queue as the rest of the XEvents. It
would be nicer for it be placed somewhere else so we could just wait
on that queue without having to deal with other possible events in
there. In theory, xcb could do that with special events, but it doesn't
really matter in practice.
Unsurprisingly, this doesn't work on NVIDIA. Well NVIDIA does actually
receive presentation events, but for whatever the calculations used make
timings worse which defeats the purpose. This works perfectly fine on
Mesa however. Utilizing the previous commit that detects Xrandr
providers, we can enable this mechanism for users that have both Mesa
and not NVIDIA (to avoid messing up anyone that has a switchable
graphics system or such). Patches welcome if anyone figures out how to
fix this on NVIDIA.
Unlike the EGL/GLX sync extensions, the present extension works with any
graphics API (good for vulkan since its timing extension has been in
development hell). NVIDIA also happens to have zero support for the
EGL/GLX sync extensions, so we can just remove it with no loss. Only
Xorg ever used it and other backends already have their own present
methods. vo_vdpau VO is a special case that has its own fancying timing
code in its flip_page. This presumably works well, and I have no way of
testing it so just leave it as it is.
Wayland had some specific code that it used for implementing the
presentation time protocol. It turns out that xorg's present extension
is extremely similar, so it would be silly to duplicate this whole mess
again. Factor this out to separate, independent code and introduce the
mp_present struct which is used for handling the ust/msc values and some
other associated values. Also, add in some helper functions so all the
dirty details live specifically in present_sync. The only
wayland-specific part is actually obtaining ust/msc values. Since only
wayland or xorg are expected to use this, add a conditional to the build
that only adds this file when either one of those are present.
You may observe that sbc is completely omitted. This field existed in
wayland, but was completely unused (presentation time doesn't return
this). Xorg's present extension also doesn't use this so just get rid of
it all together. The actual calculation is slightly altered so it is
correct for our purposes. We want to get the presentation event of the
last frame that was just occured (this function executes right after the
buffer swap). The adjustment is to just remove the vsync_duration
subtraction. Also, The overly-complicated queue approach is removed.
This has no actual use in practice (on wayland or xorg). Presentation
statistics are only ever used after the immediate preceding swap to
update vsync timings or thrown away.
Technically this was wrong. If you passed -Dvdpau=enabled but did not
have x11 (a requirement for this), the build would silently just not
build the vdpau VO. The correct behavior is for it to be a hard error.
Accomplish this by using the require function and making sure that x11
is indeed being used before attempting to find the library.
In win32 build, if libass and libfontconfig appear after libmingwex
during linking, crash happens whenever fontconfig calls to opendir().
Moving them before ffmpeg makes sure they always appear first.

This is the new FFmpeg channel layout structure, which now
combines channel count and layout into a single location.
Only unspecified (channel count only) and native (channel layout
mask based) layouts are currently supported for the initial move
towards non-deprecated APIs.
This driver makes use of dmabuffer and viewporter interfaces
to enable efficient display of vaapi surfaces, avoiding
any unnecessary colour space conversion, and avoiding scaling
or colour conversion using GPU shader resources.
Some compiler flags were passed to mpv in order to get it to build as a
gui application on windows. However on the meson build, this always
resulted in mpv being built as a console application. This is because
the function for making executables in meson specifically has a kwarg
called win_subsystem* which defaults to 'console'. That always added
link arguments at the end which compiled mpv.exe as a console
application. The correct thing to do is to remove all of the
subsystem-related flags in the meson build and use the win_subsystem
kwarg as intended by setting it to 'windows,6.0'. For mpv.com, we can
remove the -Wl,--subsystem,console flag since meson will set this by
default in that executable. This makes mpv.exe function correctly and
open with the pseudo-gui while mpv.com acts as a console wrapper.

This makes use of the new frame acquire/release callbacks to hold on to
hwdec images only as long as necessary. This should greatly improve the
smoothness/efficiency of hwdec interop, by not holding on to them for
longer than needed.
This also avoids the need to pool hwdec mappers altogether.
Should fix#10067 as well, since frames are now only mapped when we
actually use them.
There's really nothing vulkan-specific about this hwdec wrapper, and it
actually works perfectly fine with an OpenGL-based ra_pl. This is not
hugely important at the time, but I still think it makes sense in case
we ever decide to make vo_gpu_next wrap OpenGL contexts to ra_pl instead
of exposing the underlying ra_gl.
libplacebo v198 fixed this properly by adding the ability to flip planes
directly, which is done automatically by the swapchain helpers.
As such, we no longer need to concern ourselves with hacky logic to flip
planes using the crop. This also removes the need for the OSD coordinate
hack on OpenGL.
Render subs at the output resolution, rather than the video resolution.
Uses the new APIs found in libplacebo 197+, to allow controlling the OSD
resolution even for image-attached overlays.
Also fixes an issue where the overlay state did not get correctly
updated while paused. To avoid regenerating the OSD / flushing the cache
constantly, we keep track of OSD changes and only regenerate the OSD
when the OSD state is expected to change in some way (e.g. resolution
change). This requires introducing a new VOCTRL to inform the VO when
the UPDATE_OSD-tagged options have changed.
Fixes#9744, #9524, #9399 and #9398.
See the previous commit for the full explanation. Basically, luajit 2.0
has a bad pc file on macos that causes libmpv to fail during build. The
workaround was, if the os was darwin and luajit was found, to save a
full luajit dep and a partial luajit dep with the link args removed. The
partial dep was used for compiling libmpv, and the full dep was used for
the actual mpv executable. This worked and was needed for the CI to pass
but it sucked. Since the previous commit now makes the CI grab lua 5.1,
we don't need all this crap anymore. Just delete it and treat the
dependency normally.
This does effectively mean that building libmpv with luajit 2.0 on macOS
will no longer work with the meson build. However libraries not being
built correctly is not a mpv-specific issue. The waf build will succeed
for some reason, but it has known issues and it would be better if it
just failed honestly. An upstream developer said years ago that that
macOS users should use the 2.1 branch (and there's no release of
course). In any case, no macOS user should be building mpv with luajit
2.0, so we shouldn't be going out of our way to support this.

This has been the latest stable release for about half a year now. This
version in particular lets us get rid of all the deprecation warnings in
the older code. (See the following commits)
This define was always just a stopgap for that two month period (August
2021 - October 2021) where the bytes_read field in ffmpeg was completely
missing. Before that time, it was a private member in a struct (which
mpv used). Afterwards, it officially became public. Fortunately, the
lack of this field never actually made it into a release, so it could
have only possibly affected people building from the master branch.
Since ffmpeg 5.0 came out recently, and it's been plenty of months since
that two month window, we can go ahead and drop this check. This
finishes up the work done in 78cfeee2b9.
Sidenote: the cached ffmpeg version in the mingw ci were from that time
period when the bytes_read field was missing. The N in the workflow is
bumped to force a full rebuild and fresh clone of ffmpeg.
Changes:
* fixed hangups in the loop function and in some other cases
* refactoring according to @michaelforney's recommendations in #8314
* a few minor and/or cosmetic changes
* ability to build ao_sndio using meson
Warning from meson:
WARNING: You should add the boolean check kwarg to the run_command call.
It currently defaults to false,
but it will default to true in future releases of meson.
See also: https://github.com/mesonbuild/meson/issues/9300
All of the run_command() calls currently use need to succeed for the
build to work properly.
The AO provides a way for mpv to directly submit audio to the PipeWire
audio server.
Doing this directly instead of going through the various compatibility
layers provided by PipeWire has the following advantages:
* It reduces complexity of going through the compatibility layers
* It allows a richer integration between mpv and PipeWire
(for example for metadata)
* Some users report issues with the compatibility layers that to not
occur with the native AO
For now the AO is ordered after all the other relevant AOs, so it will
most probably not be picked up by default.
This is for the following reasons:
* Currently it is not possible to detect if the PipeWire daemon that mpv
connects to is actually driving the system audio.
(https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1835)
* It gives the AO time to stabilize before it is used by everyone.

There was some breakage with regards to the iconv detection in some
older meson versions. This was all settled in 0.60.3 and now it simply
just works. Remove the workarounds and bump the needed meson version to
0.60.3.
Back when the meson build was still in the PR state, this particular
variable was a dictionary. Later, it was refactored to simply be a
feature object instead. All uses of egl_drm['use'] should have been
replaced with egl_drm.allowed() but this particular line was missed
(that's what I get for not just doing find/replace). The conditional in
this line is usually satisified before egl_drm ever needs to be checked
which was why no one noticed until now. Fixes#9631.
shaderc is a special case dependency in meson. According to the
documentation*, it first checks for shaderc_shared and will fallback to
shaderc_combined (the order is reversed if the static keyword is true).
However, shaderc also has a third .pc file (shaderc_static) which should
be checked. The meson documentation doesn't indicate this, but it also
actually checks shaderc_static*. shaderc_combined is first checked if
meson looks for static libs and if that is not found it tries
shaderc_static. So this extra fallback check is not needed.
*: https://mesonbuild.com/Dependencies.html#shaderc
*: a2934ca9d1/mesonbuild/dependencies/misc.py (L539)
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.
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).
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.
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.
