Writing an image either with vo_image or with a screenshot will strip
the colorspace info because it allocates a new mp_image that contains
the same data as the old image after calling mp_image_params_guess_csp.
However, mp_image_params_guess_csp cannot always guess the appropriate
colorspace, so it picks a "sane default." Since this function also
changes parameters so the space always makes sense, this extra info
isn't harmful and allows screenshots and vo_image outs to be properly
tagged with the correct colorspace.
Fixes#10988.
Previously, this defaulted to yes and configure-bounds from the
compositor would always apply. In the case where the user explicitly set
autofit or geometry, this could be confusing because configure-bounds
would take precedence over it. Instead, let's add an auto choice and
make that the default. If we detect that the option is on auto and that
there is autofit/geometry being set, then ignore the event. This should
be more intuitive since someone who bothers to explicitly set mpv's
geometry would naturally expect that geometry to actually apply.
Semi-regression although this option never really did what the manual
said until recently. In the past, this option also controlled whether or
not mpv set the wayland buffer_scale to the value of the wl_output or
force it 1. This had varying effects depending on the exact compositor
configuration. That logic has now all been removed and this option now
only controls whether or not to scale the window with the hidpi scale
factor we get from the compositor. i.e. it actually does what the
manual says now.
Regressed from 879824a47f. The geometry
needs to be explictly recalculated now. Change up this function a little
bit also give it the ability to directly perform a resize after the
fact. This is a common workflow and we'll be using it in the next
commit.
PresentNotifyMSC turns out to be not only redundant, but also harmful with
mesa-backed egl/glx/vulkan VOs because for all of them, mesa uses
PresentPixmap behind the scenes when DRI3 is available, which already
spawns a PresentCompleteNotify event when the buffer swap actually
finishes. This is important because without using the timing information
from these PresentCompleteKindPixmap events, there's no way for mpv to know
exactly when a frame becomes visible on the display.
By using PresentNotifyMSC in conjunction with DRI3-enabled mesa, two
problems are created:
1. mpv assumes that a vblank won't elapse (i.e., it assumes the current MSC
won't change) between the time when mesa enqueues the buffer swap and
the time when mpv calls PresentNotifyMSC to ask xorg for a notification
at the next MSC, relative to the current MSC at the time that xorg reads
it for the PresentNotifyMSC call. This means that mpv could get a
notification one or more vblanks later than it expects, since the
intention here is for mpv to get a notification at the MSC that the
buffer swap completes.
2. mpv assumes that a buffer swap always takes one vblank to complete,
which isn't always true. A buffer swap (i.e., a page flip) could take
longer than that depending on hardware conditions (if the GPU is running
slowly or needs to exit a low-power state), scheduling delays (under
heavy system or GPU load), or unfortunate timing (if the raster scan
line happens to be at one of the last few rows of pixels and a vblank
elapses just before the buffer swap is enqueued).
This causes mpv to have a faulty assumption of when frames become visible.
Since mpv already receives the PresentCompleteNotify events generated by
mesa's buffer swaps under the hood, the PresentNotifyMSC usage is unneeded
and just throws a wrench in mpv's vsync timing when xpresent is enabled.
Simply removing the PresentNotifyMSC usage from the egl, glx, and vulkan
VOs fixes the xpresent vsync timing.
This protocol is pretty important since it finally lets us solve the
longstanding issue of fractional scaling in wayland (no more mpv doing
rendering over the target resolution and then being scaled down). This
protocol also can completely replace the buffer_scale usage that we are
currently using for integer scaling so hopefully this can be removed
sometime in the future. Note that vo_dmabuf_wayland is omitted from the
fractional scale handling because we want the compositor to handle all
the scaling for that VO.
Fixes#9443.
This is in preparation for fractional scaling support. Basically, redo
all the coordinates in wayland so that wl->geometry is equal exactly to
what is being put out to the screen (no extra wl->scaling multiplication
required). The wl->vdparams variable is also eliminated for simplicity.
This changes mpv's behavior on wayland with hidpi scaling but that will
be addressed in more detail with the next commit.
For OpenGL, this is based on simply comparing GL_VENDOR strings against
a list of allowed vendors.

--vd-lavc-dr defaulted to "yes", which caused issues on certain
hardware. Instead of disabling it, add a new "auto" value and
make it the default.
The "auto" choice will enable DR only when we can request host-cached
buffers (as signalled by the new VO_DR_FLAG_HOST_CACHED).

A longstanding pain point of the drm VOs is the relative lack of state
sharing. While drm_common does provide some sharing, it's far less than
other platforms like x11 or wayland. What we do here is essentially copy
them by creating a new vo_drm_state struct and using it in vo_drm and
context_drm_egl. Much of the functionality that was essentially
duplicated in both VOs/contexts is now reduced simple functions in
drm_common. The usage of the term 'kms' was also mostly eliminated since
this is libdrm nowadays from a userspace perspective.
This handle type was only needed for backwards compatibility with
windows 7. Dropping it allows us to simplify the code: there is no
longer a need for runtime checks, as the handle type can now be
statically assigned based on the platform.
The motivating usecase here, apart from code simplification, is a
desired switch to timeline semaphores, which (in the CUDA API) only
supports the non-KMT win32 handles.
It's worth pointing out that we need no runtime check for
IsWindows8OrGreater(), because the `export_caps.sync` check will already
fail on versions of windows not supporting PL_HANDLE_WIN32.
Officially, the most cursed part of the wayland code in mpv (third or
fourth try now?) This time, let's allocate a pool during init
(arbitrarily set to the maximum swapchain length mpv allows, 8; don't
even know if this actually works in wayland). Then we add/remove
feedbacks from the pool during the lifecycle of the VO, and clean it up
all at the end. Hopefully, this does the trick for good this time.
This ended up being a bad idea. The problem is that it introduces
ordering when destroying events (something we weren't worried about
before) and Lynne pointed out a problem with the callback not also being
destroyed before the surface in IRC. Just undo this and go with a
different approach (next commit). P.S. the wayland_dispatch_events name
change is kept though because I like that better.
This reverts commit aa8ddfcdf3.
In debug mode the macro causes an assertion failure.
In release mode it works differently and tells the compiler that it can
assume the codepath will never execute. For this reason I was conversative
in replacing it, e.g. in mpv-internal code that exhausts all valid values
of an enum or when a condition is clear from directly preceding code.
The only real reason this was ever supported is because it was
dramatically simpler than v4, so it was put in as an initial
implementation. Later, v4 support was added and we left v2 for
compatibility, but let's just drop it. Compositors all use v4 nowadays,
and v2 is significantly limited (no modifier support for example). It's
better to just remove this dead code for simplicity.
This was already returning true/false but the type was int. Also
simplify a few places in the wayland contexts where we can just return
the value of this function instead of doing redundant checks.
Instead of just returning true/false, it's better to have this function
cleanup itself. We can eliminate some redundant uninit calls elsewhere
in the code as well.
There's several functions that are used for initializing mpv on a
certain platform (x11, wayland, etc.). These currently are all int, but
they actually return 1 and 0 like a boolean. This gets a bit confusing
because actual vo preinit functions return 0 and -1 instead. Just make
these all bool instead and return true/false to make it clearer.
vk->surface is a handle and not a pointer, so assign VK_NULL_HANDLE.
This fixes the following build error on 32bit Windows when using clang for example,
which errors out when assigning a 32bit pointer to a 64bit integer:
../mpv-0.35.0/video/out/vulkan/utils.c:37:21:
error: incompatible pointer to integer conversion assigning to 'VkSurfaceKHR' (aka 'unsigned long long') from 'void *' [-Wint-conversion]
vk->surface = NULL;

Similar to some other issues we've had with unprocessed compositor
events. When quitting mpv, there's two things we should be doing:
dispatching any last minute wayland events and then waiting for a
compositor reply. Luckily, there's already an internal helper for this
(renamed to wayland_dispatch_events for consistency) that we can use.
All of the special casing of wl->feedback becomes unneccesary and we can
remove this from vo_wayland_state with this method. Fixes#110022.
In the event of a failed wayland initalization, the display_fd is
actually 0 instead of -1 which would correctly indicate it doesn't
exist. Also move the fd check inside vo_wayland_dispatch_events since
that function shouldn't ever do anything if we don't actually have a
display fd.
We have a use_present bool that keeps track of whether or not to use
presentation time. However, the creation of the feedback listener
actually wasn't checking this and was instead checking for the existence
of wl->presentation. There's no point in always creating the
listener and feedback if mpv isn't actually going to use it. Just change
it to use_present instead.
