this adds a "standard" api for ui scripts and thumbnailers to
communicate with each other, based on the simple thumbfast api
[0].
the api works as follows:
* To issue a thumbnail draw command, the UI script will set the
property `user-data/osc/draw-preview`.
* To clear the thumbnail, the UI script will set the previously
mentioned property to `nil`.
a more ideal api would make it so that the thumbnailer script
only generates the thumbnail and doesn't need to draw at all.
but such api is vastly more complex [4] and would require a lot
more work and maintenance on mpv's side.
this is a decent enough api that allows arbitrary thumbnailers
and ui scripts to communicate between each other and work
together, while being simple enough that it can be supported
without too much maintenance.
this change has been tested with work with thumbfast [1]. and
for demonstration that this api can be useful outside of osc, it
has also been tested to work on mfpbar's thumbnailer branch [2].
the code to determine thumbnail x,y is based on the osc fork
inside of thumbfast [3].

Subtitles in general have constant brightness, but currently
--image-subs-hdr-peak=video uses detected peak value which is not synced
with scene and undesirable.
Add new modes that allow using static peak metadata or per-scene metadata.
704afb8968 assumed that HDR image
subtitles target SDR white. However, this is incorrect according to
UHD BD spec version 3.2:
> CLUTs of Presentation Graphics streams and Interactive Graphics streams
> are prepared by content author according to dynamic range property of
> the Primary video stream.
> If a Primary video stream is HDR, the Graphics streams have CLUTs
> expressed in BT.2020 color space primaries and ST2084 EOTF.
> If a Primary video stream is SDR, the Graphics streams have CLUTs
> expressed in BT.709 color space primaries and BT.1886 EOTF.
This means that PGS subtitles always have the same colorspace and HDR
dynamic range as the video, so the target peak should also be the same.
This is also supported by the BD-J spec (which displays PGS graphics):
> However the BD-ROM player does not support color space conversion nor
> dynamic range conversion of Java graphics and Background plane when
> mixing with video plane.
The Graphics model spec further states:
> The composited image on the graphics plane is transformed to full color
> and transparency by the CLUT module and then overlaid on the video
> image.
These sentences indicate that BD-ROM players simply overlay the decoded
graphics onto the video without any kind of conversion.
Change the default of image-subs-hdr-peak to 1000 to fix this.
This accommodates most HDR videos with a peak brightness of 1000 nits
and some bad HDR videos with 10000 nits peak brightness due to reencoding
and mixed with unmodified subtitles.
If there are compatibility issues, the option can be manually
set to sdr or video.

This has been deprecated for 8 years, since 9eadc068fa, with a visible
warning. Removing it has the benefit of not spamming every log file with
lua-settings searches.
Alpha blending is done in gamma light of the target, when the overlay is
drawn. Depending on VO and target format, the alpha value can act quite
differently.
Lower it a little to avoid excessive transparency in some cases. This
should be fixed or workaround in better way, but for now just adjust the
value.
This adds proper support for MPEG-TS programs and HLS variants. Now
program selection is exposed as editions and tracks are grouped under
such edition. If there are external tracks added, they are available in
all editions.
trying to autocreate playlist when the file is a fifo breaks
playback. the bug report is a special case of `/dev/fd/*` but
even for named fifos, opening and closing them can cause the
other end to stop writing.

Some commands have named arguments named "name", which conflict with
the "name" entry used to specify command name in mpv_command_node, so
they cannot be used with mpv_command_node.
These commands include:
set, del, change-list, add, cycle, multiply, enable-section,
disable-section, define-section, script-binding, keybind, keypress,
keydown, keyup, apply-profile.
This makes mpv_command_node accept command name as key "_name", so
"name" can be used to specify command arguments. For compatibility,
if "_name" entry does not exist, then "name" is used as fallback.
Add optional 'default-value' and 'choices' fields where appropriate
for command arguments in the 'command-list' property. Update
documentation to reflect the command-list schema change.

Using vo_vaapi has already been heavily discouraged for years since
years since 5c313f1f59. More importantly,
it's just fundamentally broken on most hardware, serves no real purpose,
and well we shouldn't just ship broken stuff. vo_vaapi largely only ever
worked correctly on some intel hardware. The VO relies on certain API
calls that other vendors never implemented so things like the OSD and
subtitles are just never going to work. This largely has no reason to
exist either. If you're looking for efficient playback, you can use
vo_gpu/vo_gpu_next in dumb mode with vaapi decoding. You can also use
vo_dmabuf_wayland with vaapi as well to avoid even more GPU to CPU
copies and theoretically be even more efficient.
Tablet input is more similar to mouse input than it is to touch input,
so it makes sens to use wayland-edge-pixels-pointer instead. Also
document that it's used for tablet input, previously this was completely
undocumented.
Using "mpv --directory-filter-types= dir" as an "empty" value doesn't
work, because that will create a list where the first value is an empty
string, so get_directory_filter() returns AUTO_NONE instead of AUTO_ANY.
You need to use --directory-filter-types-clr instead, to create a proper
empty list.
I suppose this is kind of obvious in hindsight, but it took me quite
some time and digging through the mpv source to figure this out –
initially I assumed it must be a bug of some sort.
So clarify what "empty list" means.
When force-window-position=no place window on requested position only on
init (when VO requests `force_pos`), except that keep existing
position on auto resizes.
This applies to both user provided geometry and default center
position.

This uses the update_data request for clipboard backends that require it.
When clipboard monitoring is disabled, the backends will no longer
fetch data when it detects data change, and will now only do that when
receiving the update_data request.
The client now needs to run this command to update the clipboard content,
otherwise the property value is outdated.
This makes sure that applications that depend on "paste once" behavior
work correctly.
This command runs in a separate worker thread so that it can be used
as a "blocking" way to update clipboard until the update notification
arrives without blocking the playback core. It accepts a maximum timeout
parameter. This uses the existing mp_cancel mechanism to make sure this
command can be aborted and the worker threads will not stall the player
too much when quitting mpv.
For backends that do not support update_data, this command does nothing.
Decoupling fullscreen behavior from the generalized border logic
increases the complexity and also inherently changes the behavior in a
way that is not neccesarily desirable. People in IRC notably were
confused about the window controls not being shown in fullscreen because
of this change. We could default the option to yes, but then there will
likely be people confused as to why they suddenly now have the controls
when it wasn't there previously. The best way to avoid all this is just
undo it. If someone wants special fullscreen behavior with
windowcontrols, this can be done with auto profiles already. There's not
much utility in having a separate option.
This reverts commit 3b66428152.
There is concern that with certain user options or script the value of
`{sub,osd}-margin-y` value may be persisted or overwrite user option
when it's changed while OSD is visible and offset is applied.
Fix this by using dedicated option.
mmap in inherently crashy due to the file changing underneath
and requires esoteric SIGBUS handling [0] to use properly.
to reproduce, simply use "overlay-add" from a lua script with
invalid stride set and observe mpv crashing with SIGBUS.
here we're just copying the file content (introduced in
549a9ea) and munmaping it immediately so there's no real need
to be using mmap to begin with. avoid the issue entirely by just
reading the file directly with fseek+fread with optimization for
the common stride case.
one notable difference is that since dup-ed fds share same
offset, the source "fd" that's coming from client will now have
it's offset modified. `pread` could avoid this issue but it's
not supported on windows.

This allows to retain deadzone in the middle of the screen when both top
and bottom bars are enabled. We also doesn't have to show bars that
early before moving mouse down.
If `no-border` or `no-title-bar` was used, window controls would enable
also in fullscreen, this was inconsistent, as window decorations are not
visible ragardless of those options in fullscreen mode.
