Since 03cf150ff3, the only purpose of this
VOCTRL was to signal a redraw to the vo. It actualy could have been
removed in 531868fe0d, but this was
missed. The UPDATE_VIDEO flag is better anyway because it allows us to
handle a wide variety of options scattered around that require the VO to
update itself and redraw. We can remove both of the custom callbacks in
vo.c and only leave the VOCTRL_VO_OPTS_CHANGED one. Additionally, that
commit also introduced vo_set_want_redraw, but this is redundant and not
needed. The VOs that use VOCTRL_UPDATE_RENDER_OPTS already set
vo->want_redraw, and those are the only VOs where these options are
relevant in the first place. So we can remove this as well and just let
the big callback in player/command do everything.
It's only necessary to check the existance of cursor_shape_manager.
Also drop the pointer check to handle multi-seat since a removed seat
sets the cursor_seat to NULL.
For VOCTRL_SET_CURSOR_VISIBILITY, set cursors visibility for all seats.
The return is VO_NOTAVAIL is none of the seats have cursor, and
VO_FALSE if setting visibility failed for at least one seat.
The cursor_shape_device is per pointer, which is per seat. Handle it
together with other seat objects. This in turn also handles cursor
visibility per seat.
On a multi-seat setup, wl_registry_global advertises wl_seat multiple times,
one for each seat. if wl->seat is already set, the previous value will be
overwritten, preventing it from being freed.
Additionally, if the latter seat doesn't have the capabilities of the
former seat, the keyboard/pointer/touch input devices will be destroyed
because the current wl_seat_capabilities doesn't distinguish between
different seats. This casues keyboard/pointer/touch not working if the
latter seat has no such capabilities.
Fix this by implementing multi-seat support.
This allows receiving inputs from all devices on all seats.
All seat-specific objects (wl_keyboard/pointer/touch, wl_data_device)
are grouped with their respective seats so they can be managed together.
Note that currently inputs from all seats are interleaved with each other
and modify the same global input states.
If libplacebo manages to create a vulkan swapchain that allows
alpha composition mode to be controlled by the DWM API,
this makes it runtime changeable.
Specify cAlphaBits in PIXELFORMATDESCRIPTOR makes the pixel format
transparent, as is already the case for d3d11. Also makes the
window transparent when --alpha=yes is used.
Works on --vo=gpu and --vo=gpu-next.
25b66256d7 originally added this
property, but it did not add it to the property notification. This is
possibly because the window id doesn't appear to change on x11 even when
toggling VOs at runtime. However, windows uses this property and
apparently the id changes there so we should signal updates when
appropriate. Fixes#13495.
On wayland, depending on the wl_output protocol version used,
the display-names property can have different values. Mention
this in the documentation, like for other platforms.
Previously, libplacebo would fail to render the image since mpv was
feeding it bogus bitmaps with 0 width/height. An easy way to encounter
this would be to set sub-scale to 0 with bitmap/image subs.
Document the use cases for enabling or disabling the wheel preprocessing.
Also note that this option has no effect on any filtering already done
by the OS/driver.
This adds --input-preprocess-wheel option, which can be used to control
whether to preprocess received wheel events.
Commit 937128697f added preprocessing of
wheel events to prevent the accidental scrolling of another direction
when one direction is being scrolled for touchpads, which is problematic
with the default wheel bindings where unrelated functions (seeking and
volume) are used for the 2 directions.
However, this behavior is undesirable in the following situations:
- When custom wheel bindings are used so that the 2 directions are used
for closely related actions, such as panning. With preprocessing,
diagonal movement is impossible.
- Since the wheel deadzone was introduced to prevent accidental scrolling
for touchpads, this filtering provides no benefit for high resolution
unidirectional mouse wheels, while causing a regression where scrolling at
least 0.125 units is required to trigger the event, causing input delay.
By adding this option, these two use cases are addressed.
The current documentation lacks clarity regarding the interaction
between the `repeatable` and `complex` options. Through an analysis
of the source code (`player/lua/defaults.lua` and
`player/js/defaults.js`), it was observed that the `repeatable` option
is only meaningful when the `complex` option is not enabled.
Additionally, the `complex` option in the existing documentation is
confusing, actually `fn` can be called on key repeat when `complex` is
`true` and `repeatable` is not `true`.
To address these issues, the documentation for the `repeatable` option
was updated to specify that it only applies when the `complex` option is
not set to `true`. Furthermore, the description of the `complex` and
`event` were revised to acknowledge the occurrence of key repeat events.
It is possible to have data with empty block that contains additions. In
which case the block would not be added and the additions would leak.
Found by fuzzing.
This is technically due to the previous commits that made subtitle
rendering more efficient by eliminating redraws, but working around this
particular edge case is useless. The sub-clear-on-seek option was
originally introduced in d5940fabcd and
specifically is a workaround for completely broken mkv files. There is
no reason to use it otherwise. Because that option disables all
duplicate checking and the previous commits rework subtitle rendering in
the still image case to be dependent on keeping track of packets, the
end result is that you will get the same line rendered multiple times.
However the important case of broken mkv files with duplicate ReadOrder
fields still work just fine with --no-video. So instead of bothering
trying to make this option "work", just clarify that stuff can break
since, again, there's no reason to use it other than as a workaround for
broken files.
The previous commits optimized sub redrawing on still images/terminal so
mpv wouldn't redraw so much. There is a gap though. It only assumes
static subtitles. Since ASS can be animated, those types of subtitles
will always need redraws so we need to build in specific detection for
this. We need to build a whitelist of events in ASS that are considered
animations and then flag the packet. Additionally, there's a bunch of
annoying bookkeeping that has to be done since packets can be dropped on
seeks and so on.
This only affects two special cases: printing subtitles to the terminal
and printing subtitles on a still picture. Previously, mpv was very dumb
here and spammed this logic on every single loop. For terminal
subtitles, this isn't as big of a deal, but for the image case this is
pretty bad. The entire VO constantly redrew even when there was no need
to which can be very expensive depending on user settings.
Instead, let's rework sub_read_packets so that it also tells us whether
or not the subtitle packets update in some way in addition to telling us
whether or not to read more. Since we cache all packets thanks to the
previous commit, we can leverage this information to make a guess
whether or not the current subtitle packet is supposed to be visible on
the screen. Because the redraw now only happens when it is needed, the
mp_set_timeout_hack can be removed.
Previously, mpv only saved a strict limit of two packets while decoding
subtitles, but it is a bit incomplete. Firstly, it's certainly possible
for there to be more than two subtitles visible at once. And also, it
did not take into account preloading. Rework this mechanism so that it
is a growable array that can store as many packets as we want. Note that
in this commit, the packets are only ever discarded on reset or destroy,
so in theory it could grow forever. Some discarding logic will be added
in the next commit since it is inherently tied to other things.
This avoids clearing the queued frame and the currently displayed one on
VO reconfiguration requests that happen when new frames arrive. Instead,
let those frames be fully displayed.
Fixes mf:// playback issues introduced after commit ef11d31.
Instead of removing the frame timing check embrace and fix it to wake up
the playloop as needed. The frame display duration is problematic to
handle as both VO and playloop thread would already be sleeping, but in
certain use cases it is needed to display frames in full, so in this
case, let the VO sleep to the end of frame, wake up the core as
requested and go back sleeping.
Note that this patch series reintroduces 0c9ac5835, which is esenitally
fixed in this commit. It is still not perfect, but it is better than
just busy waiting on playloop, even if those events when this would be
needed are quite rare.
the observer is registered on every call of the start function. this
could lead to several registered observers for the same event and
several calls to the make current function, even though we only need it
once per event.
properly remove the observer on stop, so we only ever have one observer
registered.
