This small regression was introduced by #7216. Previously, the wayland
backend used a trick which kept track of the previous fullscreen state
and used that logic for showing the cursor. Since vo_opts now keeps
track of the current fullscreen state, most of this stopped being
neccessary.
However, there was one edge case where the cursor didn't
behave the same: passing a fullscreen flag for the inital window. The
cursor would initially be visible here which is not desirable. This can
be remedied pretty easily by just setting the cursor visiblity to false
if the pointer entry event occurs on fullscreen. The only thing we need
to do is to make sure that the autohide delay isn't completely disabled
(i.e. the cursor is always visible). Hence the need for the previous
commit.
The remaining legacy VOCTRLs are for the fullscreen and border
properties. For fullscreen this largely just replacing the private
state field with the vo option but there are small semantic
differences that we need to be careful of.
For the border setting, it's trivial as we don't have external
mechanisms for changing the state, but I also can't test it as
I'm not using a compositor that supports it.
I wanted to get this done quickly as I introduced the new VOCTRL
behaviour for minimize and maximize and it was immediately made
legacy, so best to purge it before anyone gets confused.
I did not sort out fullscreen as that's more involved and not something
I've educated myself about yet. But I did replace the VOCTRL_FULLSCREEN
usage with the new option change mechanism as that seemed simple
enough.
We primarily care about pseudo-decorations for wayland, where
the compositor may not support server-side decorations. So let's
implement the minimize and maximize commands and return the
maximized window state.
At least with gnome-shell (I know, I know), the compositor does
not provide the old window size when leaving the maximized state.
Instead, we get a toplevel_config event with a 0x0 size and no
additional states.
Today, we already save the window geometry to restore it when leaving
the fullscreen state, so we just need a small change for it to
kick in for leaving the maximized state. If I read this correctly,
we'll still respect the size passed by a compositor that actually
provides the old size.
Rather than hard-coding the edge grab zone width, we can make it
user configurable. It seems worthwhile to have separate configs
for pointer and touch usage as the defaults should be different,
and a user might have both input methods in use.
Today, we support resizing wayland windows when we detect a touch
event in a defined grab zone. As part of implementing
pseudo-decorations, we should have equivalent functionality for
mouse input. And if we detect support for actual decorations we
will not activate the grab zone as the decorations will provide this.
There's 2 stupid things here that need to be fixed. First of all,
vulkan wasn't actually using presentation time because somehow the
get_vsync function in context.c disappeared. Secondly, if the mpv window
was hidden it was updating the ust time based on the refresh_usec but
really it should simply just not feed any information to the vsync info
structure. So this adds some logic to assume whether or not a window is
hidden.
The old way of using wayland in mpv relied on an external renderloop for
semi-accurate timings. This had multiple issues though. Display sync
would break whenever the window was hidden (since the frame callback
stopped being executed) which was really annoying. Also the entire
external renderloop logic was kind of fragile and didn't play well with
mpv's internal structure (i.e. using presentation time in that old
paradigm breaks stats.lua).
Basically the problem is that swap buffers blocks on wayland which is
crap whenever you hide the mpv window since it looks up the entire
player. So you have to make swap buffers not block, but this has a
different problem. Timings will be terrible if you use the unblocked
swap buffers call.
Based on some discussion in #wayland, the trick here is relatively
simple and works well enough for our purposes. Instead we basically
build a way to block with a timeout in the wayland buffer swap
functions.
A bool is set in the frame callback function that indicates whether or
not mpv is waiting for a frame to be displayed. In the actual buffer
swap function, we enter into a while loop waiting for this flag to be
set. At the same time, the wl_display is polled to block the thread and
wakeup if it receives any events from the compositor. This loop only
breaks if enough time has passed or if the frame callback bool is
received.
In the near future, it is better to set whether or not frame a frame has
been displayed in the presentation feedback. However as a first pass,
doing it in the frame callback is more than good enough.
The "downside" is that we render frames that aren't actually shown on
screen when the player is hidden (it seems like wayland people don't
like that). But who cares. Accurate timings are way more important. It's
probably not too hard to add that behavior back in the player though.
The externally driven renderloop was originally added for the wayland
context (to make display sync somewhat work), but it has a lot of issues
with mpv's internal structure. A different approach should be used.
This reverts commit a743fef837.
Dumb idea. The correct thing to do is to fix the preinit and context
creation so that the uninit is correctly executed when probing fails
(and then everything gets freed).
This reverts commit defc8f359c.
wm4 mentioned that the wayland autoprobe leaked. A simple oversight in
the wayland_common code forgot to free the vo_wayland_state if
vo_wayland_init returned false.
I previously skipped creating the wl_output if the --fullscreen flag
with no --fsscreen_id was inputted, so the fullscreen video lands on the
correct output (where mpv was launched). This has breakage if someone
combines the --autofit flag (or other similar options with it). Instead,
just actually read xdg_shell spec and realize that you can pass NULL to
xdg_toplevel_set_fullscreen and let the compositor choose the output if
the user doesn't specify it. If this has issues, get a better
compositor.
Certain mpv config options require wl->current_output to be created
before the video can actually start rendering. Just always create it
here if the current_output doesn't exist (the one exception being the
--fs option with no --fs-screen flag). Incidentally, this also fixes
--fs-screen not working on wayland.
On wayland the cursor has to be configured each time the pointer enters.
Currently if the window (re)gains the focus, the pointer is not hidden,
even when configured. After the mouse has been moved the pointer hides
correctly.
https://wayland.freedesktop.org/docs/html/apa.html#protocol-spec-wl_pointer:
wl_pointer::enter - enter event
...
When a seat's focus enters a surface, the pointer image is undefined
and a client should respond to this event by setting an appropriate
pointer image with the set_cursor request.
Fixes#6185.

Previously, the only mouse buttons supported in wayland were left,
right, and middle click. This adds the thumb back/forward buttons as
valid bindings. Also it removes the old, default behavior of always
sending a right click if an unrecognized mouse button is clicked.
In a related but different fix, the magnitude of an axis event in
wayland is not important to mpv since it internally handles all scaling.
The only thing we care about is getting the sign when the event occurs.
This one is probably not terribly obvious from just the valgrind log,
but a wayland dev explained it to me just a second ago. Whenever mpv
sends events to the screen with wl_display_dispatch, wayland internally
allocates memory to a struct wl_proxy object if a new id is found. Quite
a few more things happen to that proxy object, but eventually mpv stores
the data on the client-side in a wrapper type of struct (struct
wl_data_offer). mpv's data_device_listener keeps track of those proxies
and frees the memory when appropriate. Of course, mpv is constantly
sending events to the screen and does so until the user quits the
player. What happens here is that one final wl_display_dispatch is called
right before the user quits the player and before mpv's
data_device_listener can handle that object. So the result is that you
always have one extra dangling proxy that doesn't get properly freed.
The solution is to just simply call wl_data_offer_destroy before closing
the wl_display to free that final dangling wl_proxy.
This is the naming xdg-shell stable adopted, it doesn’t make much sense
to keep using “shell” everywhere with all functions calling it
“wm_base”.
Finishes what 76211609e3 started.
Fixes display-sync (though if you change virtual desktops you'll need to seek
to re-enable display-sync) partially under wayland.
As an advantage, rendering is completely disabled if you change desktops or
alt+tab so you lose no performance if you leave mpv running elsewhere as long
as it isn't visible.
This could also be ported to other VOs which supports it.
Since we divide by it in a couple of places and compositors can be crazy,
its better to be safe than sorry.
Also checks cursor spawn durinig init (pointless since it does again on
cursor entry but its more correct).
It seems the cursor hadn't had its position properly adjusted when scaled.
Hence, bring back correct buffer scaling to make the cursor look fine.
Also the cursor surface now gets created sooner so that's better.
Every compositor (including toy compositors) has had support for wl_output v2
since forever, so there's little point in supporting degraded output for 5 year
old releases (especially considering we require zxdg6 which is far more recent).
It turns out compositors which do scaling scale the cursor as well,
so every single surface needs to get scaled too.
Also, 32 corresponds to the default size for both GTK+ and KDE.
This commit:
- Implements output tracking (e.g. monitor plug/unplug)
- Creates the surface during registry (no other dependencies)
- Queues the callback immediately after surface creation
- Cleaner and better event handling (functions return directly)
- Better reconfigure handling (resizes reduced to 1 during init)
- Don't unnecessarily resize (if dimensions match)
Apart from that fixes 2 potential memory leaks (mime type and window
title), 2 string ownership issues (output name and make need to be
dup'd), fixes some style issues (switches were indented) and finally
adds messages when disabling/enabling idle inhibition.
The callback setter function was removed in preparation for the commit
which will use the frame event cb because it was unnecessary.
The VO code resets each flag individually, and it doesn't do it for this one.
Also make the prints use the struct names rather than the hardcoded ones,
forgot to add those to the last wayland_common commit.
The wayland code was written more than 4 years ago when wayland wasn't
even at version 1.0. This commit rewrites everything in a more modern way,
switches to using the new xdg v6 shell interface which solves a lot of bugs
and makes mpv tiling-friedly, adds support for drag and drop, adds support
for touchscreens, adds support for KDE's server decorations protocol,
and finally adds support for the new idle-inhibitor protocol.
It does not yet use the frame callback as a main rendering loop driver,
this will happen with a later commit.
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
18a45a42d5 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.
