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.
|
| |
|
|
|
| |
A user noted that this worked correctly (i.e. vsync jitter of 0) so go
ahead and add it here as a safe driver for xpresent to use.

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.

strcasestr is a GNU extension, but we can just use bstr instead to do
the same thing.

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.

Because wayland is a special snowflake, mpv wound up incorporating a lot
of logic into its render loop where visibilty checks are performed
before rendering anything (in the name of efficiency of course). Only
wayland actually uses this, but there's no reason why other backends
(x11 in this commit) can't be smarter. It's far easier on xorg since we
can just query _NET_WM_STATE_HIDDEN directly and not have to do silly
callback dances.
The function, vo_x11_check_net_wm_state_change, already tracks net wm
changes, including _NET_WM_STATE_HIDDEN. There is an already existing
window_hidden variable but that is actually just for checking if the
window was mapped and has nothing to do with this particular atom. mpv
also currently assumes that a _NET_WM_STATE_HIDDEN is exactly the same
as being minimized but according to the spec, that's not neccesarily
true (in practice, it's likely that these are the same though). Anyways,
just keep track of this state in a new variable (hidden) and use that
for determing if mpv should render or not.
There is one catch though: this cannot work if a display sync mode is
used. This is why the previous commit is needed. The display sync modes
in mpv require a blocking vsync implementation since its render loop is
directly driven by vsync. In xorg, if nothing is actually rendered, then
there's nothing for eglSwapBuffers (or FIFO for vulkan) to block on so
it returns immediately. This, of course, results in completely broken
video. We just need to check to make sure that we aren't in a display
sync mode before trying to be smart about rendering. Display sync is
power inefficient anyways, so no one is really being hurt here. As an
aside, this happens to work in wayland because there's basically a
custom (and ugly) vsync blocking function + timeout but that's off
topic.

9a7b2015e1a711a57b6e660774c36956ac59a7f6 added the --screen-name option
for x11, but it was unfortunately broken. The commit does correctly
handle vo_x11_update_screeninfo and select the correct screen. However,
vo_x11_sizehint was missed. Specifically, the force_pos bool was always
false because it only took into account --screen being set and not
--screen-name. To fix this, just add an extra condition to the force_pos
bool so it becomes true if there's a string in --screen_name. Fixes
issue #9877.

Both _NET_WM_NAME and _NET_WM_ICON_NAME (part of Extended Window Manager
Hints) require that the string is UTF-8*. mpv was not doing this and
thus violating the spec. Just sanitize the title for these two atoms.
Note that XA_WM_NAME and XA_WM_ICON_NAME have no such requirement so
those atoms are left the same. Fixes #8812.

Back when runtime updating of autofit/geometry was added for wayland and
x11 (commits: 4445ac828dca0298543103094357e64f8828ef56 and
ced92ba607ebd98687b26ef3d8c09d5f6e22cf4b respectively), the naive
assumption was that window-related geometry would always be available.
While this is true 99% of the time, this isn't a guarentee. It is
possible for certain things such as loading shaders to delay starting up
the player. This causes autofit/geometry options to be registered as a
runtime update and triggers VOCTRL_VO_OPTS_CHANGED. This ends up calling
some geometry-related functions but this happens before the actual
values are available. Hence, a nullptr was accessed which segfaults. At
least one user experienced this with a combination of options in wayland
but in theory the same thing could happen under x11.
The fix is simple. Just be sure to check that the required geometry is
available before doing any calculations. In wayland, this would be
wl->current_output. Additionally add an assert to set_geometry (we
should never use this function without wl->current_output) to be extra
sure. In x11, the check is on x11->window. Later when the reconfig for
each backend actually happens, the autofit/geometry set by the user
happens anyway so ignoring it in this case does no harm. Fixes #9381.
|

|
|
|
|
|

If a user attempted to change the window scale of a maximized window on
x11, nothing would happen since the window manager holds the size of the
window constant. Just do an unmaximize first before performing the
resize.
|
| |
|
|
|
|
|
|
|
| |
For some reason, this never existed before. Add VOCTRL_GET_DISPLAY_RES
and use it to obtain the current display's resolution from each
vo/windowing backend if applicable. Users can then access the current
display resolution as display-width and display-height as per the client
api. Note that macOS/cocoa was not attempted in this commit since the
author has no clue how to write swift.
|
| |
|
|
|
|
| |
If the window is maximized, we can't change the size immediately. In
that case, we set a bool and wait for the state to change before
triggering the resize.
|
| |
|
|
|
|
|
|
|
| |
The --screen-name and --fs-screen-name options allow for specifying
screens based on their name. For x11, this is the display name reported
by xrandr. --screen-name and --fs-screen-name mimic the --screen and
--fs-screen options respectively. If --screen is set, then --screen-name
will always do nothing. Likewise, --fs-screen-name does nothing if
--fs-screen is set.

Add a property that returns whether the window is focused, currently
only for X11 and Wayland.
My use cause for this is having an equivalent of pause-when-minimize.lua
for tiling window managers: make mpv play only while it's in the current
workspace or is focused (I'm fine with either one but prefer focus).
On X I do this by observing display-names, which is empty when the
rectangles of the display and mpv don't intersect, but on Wayland its
value doesn't change when mpv leaves the current workspace (and the same
check doesn't work since the geometries still intersect).
This could later be made writable as requested in #6252.
Note that on Wayland se shouldn't consider an unactivated window with
keyboard input focused.
The wlroots compositors I tested set activated after changing the
keyboard focus, so if you set wl->focused only in
keyboard_handle_enter() and keyboard_handle_leave() to avoid adding the
"has_keyboard_input" member, focused isn't set to true when first
opening mpv until you focus another window and focus mpv again.
Conversely, if that order can't be assumed for all compositors, we
should toggle wl->focused when necessary in keyboard_handle_enter() and
keyboard_handle_leave() as well as in handle_toplevel_config().

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.

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.

This was changed 6 years ago (444e583b6) and seemed to work fine. But it
does seem to cause issues with IceWM sometimes, while with StaticGravity
the problem is gone. Comparing both gravity values, reading the confused
source code comment, and reading the referenced commit message, I can't
determine what it even does, I just remove it.
Reproduction:
- start mpv in windowed mode, with 2 videos of different size
- switch to second video
- switch window with alt+tab
- switch back to mpv with alt+tab
- window moves to X=0
There's probably a better way to fix this. Please send a patch.

Apparently there are two different options for controlling which
screen an mpv window goes onto: --fs-screen and --screen. The former
explicitly only controls which screen a fullscreened window goes onto,
but does not appear to actually care about this option at runtime for
X11, so pressing f will always fullscreen to the screen mpv is currently
on. This means the option is of questionable usefulness for starters.
Making it worse, if you use --screen=1 --fs, mpv will actually fullscreen
on screen 0, because --fs-screen isn't set. Instead of doing that, fall
back to whatever --screen is set to.

(X11 does not support different per-screen DPI (or only via hacks), so
this is pretty simple. If other backends are going to implement this,
then they should send VO_EVENT_WIN_STATE if the DPI for the mpv window
changes by moving it to another screen or such.)

The size overflow check was inverted: instead of allowing reading only
the first dst_size bytes of the property, it allowed copying past the
property buffer (as returned by xlib). xlib doesn't return the size of
the buffer in bytes, so it has to be computed and checked manually.
Wouldn't it be great if C allowed me to write the overflow check in a
readable way, so it doesn't trick me into writing dumb security bugs?
Relying on X security is even dumber than creating a X security bug,
though, so this was not a real problem. But I found that one specific
call tried to read more than what the property provided, so reduce that.
Also, len*ib obviously can't overflow, so there's an additional layer of
dumb to this whole thing.
While we're at dumb things, why the hell does xlib use "long" for 32 bit
types. It's a god damn pain.

In this combination, the [current-]window-scale properties still
incorrectly applied scaling.
For some reason, vo_calc_window_geometry2() handled this option
(basically ignored the dpi_scale parameter passed to it), but since the
DPI compensation for window-scale is implemented in x11_common.c, we
need to check and honor this option here too. (What a mess.)

"window-scale" is 1.0 by default; however, x11 implicitly set that to
2.0 on hidpi screens. This made the default 2.0, which was inconsistent
with the option. The "window-scale" property jumped from 1.0 to 2.0 when
a window was created.
Avoid this by factoring the DPI into the window-scale. This makes the
UNFS_WINDOW_SIZE return a virtual size; since this value is used for the
window-scale property only, this is fine and has no further
consequences. (Originally, this was possibly meant to be used for other
purposes, but I'm perfectly fine with redoing this again should that
ever happen.)
This changes user-visible behavior, and it's as if setting window-scale
multiplies its argument by 2 suddenly. Hopefully no user will get angry.

Should restore full functionality.
The initial state setting is a bit shoddy (instead of setting the
properties before map, we use the WM commands to change it after, so you
will see the normal window state for a moment; the WM commands do not
work on unmapped windows, so fixing this would require more code).

- remove VOCTRL_FULLSCREEN and VOCTRL_GET_FULLSCREEN
- have your own m_config_cache for the fullscreen option
(vo->opts_cache cannot be used because you lose per-option change
notifications, and it'd be a mess anyway)
- use VOCTRL_VO_OPTS_CHANGED to update it
(it's used for convenience)
- when updating it, check for the fullscreen option
(wasn't sure how to do it best; currently, it compares the raw
option pointers, but this could be changed)
- do not send VO_EVENT_FULLSCREEN_STATE on FS change
- instead write the option on FS change
(assign in opt. struct + m_config_cache_write_opt)

This allows the pseudo client side decorations to be used under x11,

Use x11->opts instead of vo->opts. This doesn't matter currently, and
x11->opts is actually set to vo->opts. However, there's a chance that
either option access changes, or that the way backends integrate with
struct vo changes. This is just a preemptive change to make this less of
a mess, and it's generally a good idea to reduce accesses to struct vo
anyway.

To find the correct ICC profile X atom, the screen number was calculated
directly from the xrandr order of the screens.
But if a primary screen is set, it should be the first Xinerama screen,
even if it is not the first xrandr screen.

Regression from 8e3308d687c3acdd0d572015b06efd5b492d93ee.
Broken cases were:
* --no-cursor-autohide acted like --cursor-autohide=always.
* --cursor-autohide-fs-only always hid the cursor if starting
non-fullscreen; entering fullscreen at least once fixed it.

On a multi monitor setup, when the center of the window was going off
screen, the icc profile would always switch to the profile of the first
screen.
This fixes the issue by defaulting the value to the current screen.

Using strtol and strtoul is allegedly better practice, and I'm going
for strtoul here because I'm pretty sure X11 displays cannot be in

For some reason, the X default modifier map binds shift+tab to
ISO_Left_Tab instead of the regular Tab. So to get Shift+TAB recognized
by mpv, we also need to accept ISO_Left_Tab.
This patch matches what other programs like e.g. Qt do, which treat Tab
and ISO_Left_Tab as the same thing.
God only knows why the distinction exists, and why X decides to mix up
its bindings like that.

Mouse wheel bindings have always been a cause of user confusion.
Previously, on Wayland and macOS, precise touchpads would generate AXIS
keycodes and notched mouse wheels would generate mouse button keycodes.
On Windows, both types of device would generate AXIS keycodes and on
X11, both types of device would generate mouse button keycodes. This
made it pretty difficult for users to modify their mouse-wheel bindings,
since it differed between platforms and in some cases, between devices.
To make it more confusing, the keycodes used on Windows were changed in
18a45a42d524 without a deprecation period or adequate communication to
users.
This change aims to make mouse wheel binds less confusing. Both the
mouse button and AXIS keycodes are now deprecated aliases of the new
WHEEL keycodes. This will technically break input configs on Wayland and
macOS that assign different commands to precise and non-precise scroll
events, but this is probably uncommon (if anyone does it at all) and I
think it's a fair tradeoff for finally fixing mouse wheel-related
confusion on other platforms.

mpv's mouse button numbering is based on X11 button numbering, which
allows for an arbitrary number of buttons and includes mouse wheel input
as buttons 3-6. This button numbering was used throughout the codebase
and exposed in input.conf, and it was difficult to remember which
physical button each number actually referred to and which referred to
the scroll wheel.
In practice, PC mice only have between two and five buttons and one or
two scroll wheel axes, which are more or less in the same location and
have more or less the same function. This allows us to use names to
refer to the buttons instead of numbers, which makes input.conf syntax a
lot easier to remember. It also makes the syntax robust to changes in
mpv's underlying numbering. The old MOUSE_BTNx names are still
understood as deprecated aliases of the named buttons.
This changes both the input.conf syntax and the MP_MOUSE_BTNx symbols in
the codebase, since I think both would benefit from using names over
numbers, especially since some platforms don't use X11 button numbering
and handle different mouse buttons in different windowing system events.
This also makes the names shorter, since otherwise they would be pretty
long, and it removes the high-numbered MOUSE_BTNx_DBL names, since they
weren't used.
Names are the same as used in Qt:
