Rather than after tone-mapping. This prevents overflow when the
pre-tonemapped signal contains inputs exceeding sig_peak. I also
realized that with this clipping in place, post-clipping no longer needs
to be done, so this isn't even particularly slower.
The only two exceptions to the rule are "clip" and "linear", which
relied on the post-clipping to do their tone mapping properly.
Fixes#7929
This normally gets printed by libplacebo itself when initializing the
context, but due to the way our code is structured (for convenience) we
don't have the log hook enabled by the time this function call is
relevant. So instead just print it manually as an easier work-around
than restructuring the code.
It turns out that the AMD driver doesn't bother to set the size
field in the descriptor for an exported VA surface. I guess they
assume the caller can always use lseek() and don't bother. So, we
need to use lseek() in these situations.

Guarded this behind PL_API_VER >= 88 to prevent it from exploding on
older libplacebo versions, where vaapi support does not yet work
properly on AMD due to lack of DRM modifiers.
we properly set the unfs window size on live resize end. due to a race
condition in the fullscreen events, which is also a live resize, the
unfs window size is incorrectly set to a fullscreen size. this happens
when the end fs screen event triggers before the end of live resize one.
this just adds a second condition to not be un fullscreen when updating
the unfs window size.
Mess this into the --geometry option, because I like to be
irresponsible. I considered adding a separate option, but at least this
allows me to defer the question how the hell this should work as
property (geometry simply and inherently does not).
Tested on IceWM only. Option equality test and string output not tested.
I'm tired of dealing with this frequent spawning of xdg-screensaver when
debugging and what not. xdg-screensaver was never a serious tool anyway,
it's more like some self-deprecating joke by FDO folks.
This will affect X11 on GNOME and other DEs. I'm singling out GNOME
though, because they are the ones actively sabotaging any sane
technical solutions and community cooperation.
I have been accused of taking it out on innocent GNOME users, while none
of this will reach GNOME developers. Of course that is not the
intention.
This can be used to make vo_libmpv render video to a memory buffer. It
only adds a new backend API that takes memory surfaces. All the render
API (such as frame rendering control and so on) is reused.
I'm not quite convinced of the usefulness of this, and until now I
always resisted providing something like this. It only seems to
facilitate inefficient implementation. But whatever.
Unfortunately, this duplicates the software rendering glue code yet
again (like it exists in vo_x11, vo_wlshm, vo_drm, and probably more).
But in theory, these could reuse this backend in the future, just like
vo_gpu could reuse the render_gl API.
Fixes: #7852
libplacebo exposes this feature already, because this particular type of
bug is unusually common in practice. Simply make use of it, by exposing
it as an option.
Could probably also bump the libplacebo minimum version to get rid of
the #if, but that would break debian oldoldstable or something.
Fixes#7867.
Using mediump float on GLES causes problems with kernel resampling,
PQ HDR, and possibly others. The issues are fixed by using highp,
which is available when GL_FRAGMENT_PRECISION_HIGH is defined.
--dscale= and --*scale-window= (i.e. an empty string) are respectively
valid settings for their options (and, in fact, the defaults).
This fixes the bug that it was impossible to reset e.g. tscale-window
back to the default "unset" setting after setting it once.
Credit goes to @CounterPillow for locating the cause of this bug.
For testing in VMs I guess?
This features a very broken hack that probably works. Though I didn't
test the packed format case. Again, the mismatch is essentially due to
big endian byte addresses decreasing as bit addresses increase, so you
can't represent a bit position in a byte stream with a single address,
which the mpv metadata does.
OSD is broken because repack.c doesn't support big endian. You'll have
to live with it.
For cases in which the requirements of the GPU API prevent directly
uploading a texture with a given stride, we need to fix the stride
manually in host memory. This incurs an extra memcpy, but there's not
much we can do about it. (Even in `ra_gl` land, the driver will just
hide this memcpy from the user)
Note: This code could be done better. It could only copy as many texels
as needed, and it could pick a stride that's a multiple of
`gpu->limits.align_tex_xfer_stride` for better performance. Patches
welcome (tm)
Fixes#7759
Implementation copy/pasted from:
https://code.videolan.org/videolan/libplacebo/-/commit/f793fc0480f
This brings mpv's tone mapping more in line with industry standard
practices, for a hopefully more consistent result across the board.
Note that we ignore the black point adjustment of the tone mapping
entirely. In theory we could revisit this, if we ever make black point
compensation part of the mpv rendering pipeline.
This standard says we should use a value of 203 nits instead of 100 for
mapping between SDR and HDR.
Code copied from https://code.videolan.org/videolan/libplacebo/-/commit/9d9164773
In particular, that commit also includes a test case to make sure the
implementation doesn't break roundtrips.
Relevant to #4248 and #7357.
glslang accepted this, perhaps erronneously, but mesa does not. It seems
to be incorrect. A caveat is that this means *all* SSBOs are now
coherent, but since we only use SSBOs for peak detection, that's a
non-issue. (And besides, marking something as coherent when we don't
perform any synchronization commands on it should be a no-op anyway)
Fixes#7823
since the title bar catches the mouse up and down events, the underlying
events view doesn't reset the isMoving state and no mouse movements are
signalled to the core. now we also reset the state in mouse up events
on the title bar.
Fixes#7807
The "screenshot window" command (ctrl+s by default) somehow broke video
colors with --gpu-api=vulkan --profile=gpu-hq when playback was paused.
I don't know the cause, but the rest of the code seems to imply
gl_video_reset_surfaces() needs to be called manually to flush some
caches, and it fixes the issue, so I assume there's no great mystery
here.
Commit 07b0c18 introduced some build breakages. Some breakages

Commit 6a13954d67 lowered the frequency of wakeups with this
condition. But it seems it sometimes the audio sync mode really should
get the wakeup before the frame is rendered. Normally, vo_thread is
supposed to perform this wakeup. Now the wakeup frequency is twice of
what should be needed - whatever, maybe it can be fixed properly once or
if timing is moved to the VO entirely in the future.
Fixes: #7777 (probably, untested)
When the window is mapped, some ICCCM WM_HINTS are set.
The input field is set to true and state is set to NormalState.
To quote the spec, "The input field is used to communicate to the window
manager the input focus model used by the client" and "[c]lients with
the Passive and Locally Active models should set the input flag to True".
mpv falls under the Passive Input model, since it expects keyboard input,
but only listens for key events on its single, top-level window instead
of subordinate windows (Locally Active) or the root window (Globally
Active).
From the end users prospective, all EWMH/ICCCM compliant WMs (especially
the minimalistic ones) will allow the user to focus mpv, which will allow
mpv to receive key events. If the input field is not set, WMs are
allowed to assume that mpv doesn't require focus.
I'm not sure why it only rendered OSD inside the video. Since OSD
rendering was always done on the X image (after software scaling and
color conversion), there was no technical reason for this. Maybe it was
because the code started out this way, and it was annoying to change it.
Possibly, one reason was that it didn't normally have to clear the black
bars in every frame (if video didn't cover the entire window).
Anyway, simply render OSD to the full window. This gets rid of some
rather weird stuff. It seems to look mostly like vo_wlshm now. The
uncovered regions are cleared every frame, which could probably be
avoided by being clever with the OSD renderer code, but this is where
I'm decidedly losing interest.
There was some mysterious code for aligning the image width to 8 pixels.
Replace that by attempting to align it to SIMD alignment (might matter
for libswscale, or if repack.c gets SIMD). Why are there apparently 4
different ways representing a pixel format (depth, VisualID, Visual,
XVisualInfo), but none of them seem to provide the XImage.bits_per_pixel
value (the actual size of a pixel, including padding)? Even after 33
years, X11 still seems overengineered, confusing, and inconvenient. So
just call X11 a heap of shit, and assume the worst case for alignment.
Make sure to accept only native endian mpv formats. Previously, it
didn't check, and simply matched LE, because these are usually defined
before the BE formats.
red_mask etc. are defined as unsigned long, so use that instead of
hardcoding a 32 bit limit.
Useless, but super generic! Actually may add support for other fringe
formats, however vo_x11 in itself is useless, so nothing won here. Also
I didn't bother with big endian support.
Trying to use anything other than CLOCK_MONOTONIC here would be a
disaster. No idea if it's even possible for the clockid here to be
something other than CLOCK_MONOTONIC in this function but it's better
safe than sorry. Closes#7740.
The image w and h members must match params.w and params.h, so
should not be changed directly. The helper function mp_image_set_size
is designed for this purpose, so just use that instead.
This prevents an assertion error with the rewritten draw_bmp.
Fixes#7721.
Added in libplacebo v60, unfortunately with some changes in design that
make it a bit of an awkward fit for the way timers are used in mpv.
Timer queries in libplacebo don't support "start" and "stop"-style
operations, and instead are attached directly to operations. The only
sane way of implementing this in the ra API is to have a single 'active
timer' that gets attached to every pass, taking care to sort distinct
operations into distinct pl_timer queries within that ra_timer.
This design unfortunately doesn't let us have multiple 'active timers'
concurrently, similar to the current such limitation in ra_gl. But it's
also not a big deal.
Render most of the OSD on the CPU, then draw it using a relatively
simple method. Do this for minimum code maintenance overhead. (While it
doesn't matter for vo_direct3d, and the effort spent here is probably
more than this would ever hope, I do hope to simplify the internal OSD
API for all these fringe VOs. Only vo_gpu should be allowed to do more
sophisticated things.)
If your GPU is shit (which it will be if you "want" to use vo_direct3d),
this might actually improve performance... is what I'd say, but out of
laziness a full screen sized texture gets uploaded on every OSD/subtitle
change, so maybe not.
This isn't useful anymore. We have a much better d3d11 renderer in
vo_gpu. D3D11 is available in all supported Windows versions. The
StretchRect path might still be useful for someone (???), and leaving it
at least evades conflict about users who want to keep using this VO for
inexplicable reasons. (Low power usage might be a justified reason, but
still, no.)
Also fuck the win32 platform, it's a heap of stinky shit. Microsoft is
some sort of psycho clown software company. Granted, maybe still better
than much of the rest of Silly Con Valley.
The original solution for #7017 was sort of a hack, but this hack is no
longer needed because c05e5d9d fixed the underlying issue causing this
error to be spammed in the first place. So just remove the "fix" that
apparently introduced about as many issueas it fixed.
Fixes#7719, hopefully.
This will probably make it slower. But since I don't care about
vo_vaapi, that's perfectly OK. It serves mostly as a test for the
previous commit. In addition, this code was pretty bad (custom broken
scaling and not-blending that probably broke in some situation). If that
wasn't enough, some vaapi drivers also provide only a single overlay at
a time, while this code required a bunch.
There also seems to be a Mesa bug: the overlay gets stretched when
src_x/y was not 0. Or maybe I misunderstood how this is supposed to
work. A bug is probably more likely? Nobody cares about this API.
They are sort of confusing, and they hide the fact that they have an
alpha component. Using the actual formats directly is no problem, sicne
these were useful only for big endian systems, something we can't test
anyway.
This was not intended to be committed in 0e3f893606. It disables
the extra wakeup if working==true. I've convinced myself that the wakeup
was really needed at the time, so no idea how I didn't notice this until
someone pointed it out on the commit diff on github (lol).
This resolves prefixes such as "~/" and "~~/" at the caller, instead of
relying on stream_read_file() to do it. One of the following commits
will remove this from stream_read_file() itself.
Untested.
The caller of render_frame() re-iterates without waiting if this
function returns true. That's normally meant for DS, where we draw
frames as fast as possible to let the driver perform waiting.
This was incorrect at least because the colorspace matrix attempted to
center chroma at (conceptually) 0.5, instead of 0. Also, it tried to
apply the fixed point shift logic for component sizes > 8 bit.
There is no float yuv format in mpv/ffmpeg yet, but see next commit,
which enables zimg to output it. I'm assuming zimg defines this format
such that luma is in range [0,1] and chroma in range [-0.5,0.5], with
the levels flag being ignored. This is consistent with H264/5 Annex E (I
think...), and it sort of seems to look right, so that's it.
Was broken with a zimg wrapper refucktor before the previous commit. In
addition, it seems this didn't match the vo_drm format, or the format
naming convention. So the order actually changes, and the format is
redefined. (The img_format.h comment was probably wrong.)
Change vo_gpu to the new format as well, so we can still test it.
