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.
Avoids another pitfall on systems where the first card has a primary
node but is not capable of KMS. With this change --drm-context=drm
should work correctly out-of-the-box in all cases.
On S905X (meson) boards drmModeAtomicCommit called from
disable_video_plane in hwdec_drmprime_drm.c might still be running when
another call is made from queue_flip in context_drm_egl.c.
This causes EBUSY error in queue_flip, and causes mpv to hang.
This is somewhat academic for now, as we explicitly ask for separate
layers and the scenarios where multi-plane images are required also use
complex formats that cannot be decomposed after the fact, but
nevertheless it is possible for us to consume simple multi-plane
images where there is one layer with n planes instead of n layers with
one plane each.
In these cases, we just treat the planes the same as we would if they
were each in a separate layer and everything works out.
It ought to be possible to make this work for OpenGL but I couldn't
wrap my head around how to provide the right DRM fourcc when
pretending a plane is a layer by itself. So I've left that
unimplemented.
A VRAM memory leak was present in d3d11 when `idle=yes` and playback
stops for an item. This patch re-enables some of the code which is
only used during diagnostic which fixes the issue.
libplacebo 4.157 [1] rename context.h to log.h, and left a compatibility
header. In 5.x, this header has been removed.
Since we require libplacebo 4.157 to build mpv, we can just use log.h to
fix compatibility with 5.x.

Using cmsFLAGS_HIGHRESPRECALC results in Little-CMS generating an
internal 49x49x49 3DLUT, from which it then samples our own 3DLUT. This
is completely pointless and not only destroys the accuracy of the 3DLUT,
but also results in no additional gain from increasing the 3DLUT
precision further.
The correct flag for us to be using is cmsFLAGS_NOOPTIMIZE, which
suppresses this internal 3DLUT generation and gives us the full
precision. We can also specify cmsFLAGS_NOCACHE, which is negligible but
in theory prevents Little-CMS from unnecessary pixel equality tests.
This was introduced in 7fb972fd39 and
later revised in f5a094db04. Transparency
in EGL/X11 has been broken upstream for years in Mesa unfortunately.
However, the first commit claimed to have found a way to preserve
transparency by doing a trick with picking EGLConfigs (the second commit
revises this but keeps the logic in place). However, it doesn't appear
that the first commit actually fixes anything (transparency doesn't work
on my machine) and no one else seems to have reported it working. On the
other hand, if Mesa does ever actually fix this, transparency would
immediately be broken since mpv would always set the EGL_ALPHA_SIZE to
0. Go ahead and remove this since it doesn't seem to have any actual
utility and is technically a bit of a timebomb (not that deleting two
lines is a lot of work but still) if upstream ever does fix this.
This commit kind of mixes several related things together. The main
thing is to avoid calling any XPresent functions or internal functions
related to presentation when the feature is not auto-whitelisted or
enabled by the user. Internally rework this so it all works off of a
use_present bool (have_present is eliminated because having a non-zero
present_code covers exactly the same thing) and make sure it updates on
runtime. Finally, put some actual logging in here whenever XPresent is
enabled/disabled. Fixes#10326.
With the recent addition of the libxpresent, it should improve frame
timings for most users. However, there were known cases of bad behavior
(Nvidia) which lead to a construction of a whitelist instead of just
enabling this all the time. Since there's no way to predict whatever
combination of hardware/drivers/etc. may work correctly, just give users
an option to switch the usage of xorg's presentation statistics on/off.
The default value, auto, works like before (basically, Mesa drivers and
no Nvidia are allowed), but now one can force it on/off if needed.
The old logic always reset the x11->has_mesa/has_nvidia values on every
loop through the provider. This meant that it would always just match
whatever the last provider happened to be. So in the case of a dual GPU
system, if nvidia was the very first provider and the integrated
intel/amd card was the second (in practice, this is probably mostly the
other way around), then mpv would set has_mesa to true and has_nvidia to
false and thus try to use presentation. This is not the intended
behavior. Just rework this by also checking x11->has_mesa/has_nvidia in
the loop so a true value from the previous iteration is preserved.
This code was taken from the older vo_vaapi driver, which does
use the vaapi format list, but the new driver has no use for
these formats, as it is only interested in va surfaces that
can be mapped to wl buffers. The format doesn't enter into
it at all.
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.
Unfortunately there's a certain company that makes graphics drivers that
are harder to deal with. The next commit aims to implement presentation,
but some empirical testing from users show that it's actually broken.
Give up and just tap into Xrandr so we can figure what drivers (or well,
providers by the extension terminology) are driving the screen.
Basically if we find intel, amd, or radeon, assume it's a Mesa driver.
If we find nvidia, then it must be nvidia. This detection requires randr
1.4 (which means using presentation in mpv secretly depends on randr
1.4), but this protocol version is nearly a decade old anyway so
probably 99.9% of users are fine. Do the version query check and all
that anyway just to be on the safe side.
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.
This shouldn't have mattered but apparently qtile is unable to get the
app id if you set it after the initial surface commit. Wayland is a mess
anyway so just shuffle this around so that the frame callback and
surface commit are the last things registered in vo_wayland_init. This
works around qtile and, in theory, doesn't appear to break anything
else. Fixes#10280.
Some wayland compositors (i.e. weston) get extremely picky about
committed buffer sizes not matching the configured state. In particular,
weston throws an error on you if you attempt to launch with
--window-maximized and use opengl (vo_vaapi_wayland actually errors as
well in this case, but that's a different issue). The culprit here is
actually wl_egl_window_create. This creates an initial buffer at the
sizes passed in the arguments which is what weston doesn't like.
Instead, move the egl_window creation call to the resize function. This
ensures that mpv is using the size obtained via the toplevel event, and
it should always be the buffer size we want.
This was actually always bugged, but we just got lucky that compositors
ignored it. The egl window was created only using wl->geometry's
coordinates but those do not include the scale factor. So technically,
the initial window creation always had the wrong size (off by whatever
the scaling factor is). The resize call later fixes it because that
correctly uses wl->scaling so in practice nothing bad was seen.
wlroots's master branch has started sending an error in this case
however and this is what trips it. Fix it correctly by using the scale
factor. This is what cd3b4edea0 tried to
fix (but was incorrect).
cd3b4edea0 is not correct and had some
unexpected breakage with geometry/resizing. Rather than completely
revert it, this commit restores the set_surface_scaling call as well as
rearranges some other things in the wayland init/reconfig process to
make it simplier. The next commit properly fixes what
cd3b4edea0 tried to fix.
Just a couple of small changes. First, the obvious one is to remove the
bogus wl->window_size = wl->vdparams; line in the configure conditional.
The reconfig always unconditionally sets the window_size here so there's
no need to duplicate it. The more important change is to remove the
usage of set_surface_scaling. This function is just to handle when
scaling changes and for setting the initial scale, it was called in the
reconfig. This, however, causes some weird issues in the latest
sway/wlroots where it can try to divide a buffer by an inappropriate
scale factor. This is possibly due to some weird ordering of events and
only occured in opengl for some reason.
Luckily, it turns it out it's not neccessary to set the scaling here at
all. The surface enter event is already setup to handle scale changes.
On an HIDPI display, mpv will initially assume a scale of 1 but the
surface actually enters the wl_output, it will automatically readjust
and resize itself to the appropriate scale value. This works on the
initial launch of the mpv window as well, so there's no need to special
case this in the reconfig event. This has the nice bonus of avoiding
that sway/wlroots issue as well since the buffer_scale is set much
later. Fixes#10263.
One downside of this approach is that it bypasses the mixer cache, but
while this is not ideal for performance reasons, the status quo is also
simply broken so I'd rather have a slower implementation that works than
a faster implementation that does not.
And as it turns out, updating the OSD state and invalidating the mixer
cache correctly is sufficiently nontrivial to do in a clean way, so I'd
rather have this code that I can be reasonably certain does the right
thing.
Fixes#9923 as discussed. Also fixes#9928.
Apparently _t names are reserved, and in this case it wasn't very
useful anymore (it was useful while developing it, but this code is
almost 10 years old now).
Fixes a compilation error on Solaris.
The wayland stuff is designed to update/rescale itself whenever the
wl_output scale changes. This is great, but vo_vaapi_wayland should not
actually attempt to handle any hidpi stuff. The point of this VO is to
hand off as much to the compositor as possible, so we do want the
compositor to do the scaling here (enjoy your bilinear). This fixes some
incorrect rendering that could occur with scaling values not equal 1 due
to mismatches between buffer coordinates and the surface local
coordinates. It also eliminates the need to specify
--no-hidpi-window-scale on hidpi displays (has the same practical
effect).
A bad person (AKA me) merged this stuff without paying close enough
attention to the code style. Reformat this to be in-line with the rest
of the wayland code and general mpv style (braces for functions on the
next line, horizontally aligning arguments, some cosmetic cleanups for
wayland_common.h, etc.).
So it turns out that mpv already has an mp_tag_str which makes a
readable string out of fourccs (drm formats are these).
drm_format_string, on the other hand, has a ton of baggage with having
to check different libdrm versions for certain headers, adding
compile-time defines (because there are no version defines in the libdrm
headers), etc. It's a lot simpler to just use what mpv already has and
it returns what you actually care about: i.e. is this format supported
or not. Fixes https://github.com/mpv-player/mpv-build/issues/184
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.
5774ce759a added the new output name event
and used them for the --fs-screen-name option. It turns out that the
display-names property could also make use of these names, so go ahead
and use output->name in this case if we have them. If not, fallback to
output->model like before.
These values and options were simply never looked at in the drm egl
context. This pretty much is just a copy and paste of what is in vo_drm.
Fixes#10157.
Allow screenshot-high-bit-depth=yes to work with JPEG XL
screenshots when screenshot-sw=no is set. They already work
as expected when screenshot-sw=yes is set, but this allows
the hardware screenshots to work this way too.
Since 2018, wl_surface_damage_buffer has been explicitly preferred and
recommended over wl_surface_damage*. mpv was still using the old
function in a couple of spots. The only difference is that we need to
pass buffer coordinates instead of surface coordinates. In vo_wlshm,
this is done by using vo->dwidth/vo->dheight since that is always used
whenever wl_buffers are created. In the case of the cursor surfaace, we
actually already passed buffer coordinates to it (img->width/height)
which was probablly technically wrong with wl_surface_damage, but it
doesn't really matter in practice. This requires bumping wl_compositor
to version 4 which is no problem since this dates back to 2015*.

Add Jpeg XL as a possible output format for screenshots, which
should make it possible to take fast screenshots with much better
quality than JPEG, or take lossless high-bit-depth screenshots
with lower file sizes than PNG.
It is possible for vo_gpu_next to attempt a resize before the windowing
backend is fully initialized. In practice, this can happen on wayland
which means libplacebo attempts a 0x0 resize. Depending on the API, a
0x0 resize may be allowed (vulkan or d3d11), but libplacebo just returns
a 0 in this case which mpv doesn't do anything with anyway. In the case
of opengl, this usage is explictly forbidden and will result in a
warning which may confuse users. Solve this by just not trying a resize
if dwidth and dheight in the vo are not available. Fixes#10083.
