due to the System inherent fullscreen animation the option and the
actual fullscreen state can be out of sync, leading to a wrongly
reported unfs window size in the time of the animation.
just always fall back to the window size, we keep track of, when we
either are in fullscreen or are currently switching to it.
Fixes#4323
there are two minor bugs. mpv could try to retrieve the size when in
fullscreen and would get the fullscreen size. to fix that we keep track
of the window size before going into fullscreen.
the second small bug is when using HiDPI resolution and the
--hidpi-window-scale option. we actually want the OSD to show the proper
window scale depending on the hidpi settings. before when resizing the
window to double the size it could show "window-scale: 1.0" or
"window-scale: 0.5" when resizing to normal size. now it considers the
backing scale factor and the hidpi option to return a logical correct
window size.
for a reason i can just assume some key events can vanish from the
event chain and mpv seems unresponsive.
after quite some testing i could confirm that the events are present at
the first entry point of the event chain, the sendEvent method of the
Application, and that they vanish at a point afterwards. now we use
that entry point to grab keyDown and keyUp events. we also stop
propagating those key events to prevent the no key input' error sound.
if we ever need the key events somewhere down the event chain we need
to start propagating them again. though this is not necessary currently.
i falsely assumed that the windowDidChangeScreen was meant to report
‘physical’ screen changes but was wondering why it triggers on other
events too. it actually is a event that informs us when anything
referenced by our current NSScreen is changed. even when something
referenced in the NSScreen changed the old and new NSScreen are still
equal if the physical screen didn’t change. with that my previous
optimisation broke some cases where the physical screen didn’t change
but things it referenced did, leading to a segfault when theses were
accessed. to keep the optimisation we will always update our internal
NSScreen reference but the rest only when the physical screen was
changed.
fffab30 introduced a small regression where the cursor couldn't be
unhidden after refocusing. the problem is that no mouseUp event was
reported in our events_view. work around this with a separate event
monitor. this also fixes another regression when the window is being
dragged from the title bar.
#4174
even though the mouse doesn’t move relative to the window itself, when
the window is being dragged, some outliers are still reported and
trigger the OSC.
fixes the case when mpv is opened and the cursor is within the window
bounds without moving the mouse. previously the window could only be
dragged around after the first mouse movement.
we can simplify the code because we don't need to change the bool
pointer we were given by the VOCTRL_SET_CURSOR_VISIBILITY event. i
assume this was done to work around some bugs previously to the recent
cursor refactor. i kept that because i thought it was necessary, which
wasn't in the end. after the refactor it only caused some weirdnesses i
tried to work around. without it we can get rid of some special cases
and simplify the code quite a bit.
we reported some unnecessary mouse movements and not all mouse enter
and leave events. that lead to wrongly reported activity on hover areas
like on the OSC or comparable lua scripts. sometimes menu items were
shown that shouldn't be shown or they didn't vanish because of the
missing mouse leave event.
this incorporates @torque's fix for mouse leave events that weren't
triggered during a transition, like going to fullscreen. the
tracking area was updated but the mouse never left that area because
it was never over it.
besides some known cursor visibility bugs the aforementioned changes
also revealed some other bugs that weren't reproducible before because
of the missbehavior.
known issues, in some cases the cursor doesn't show or hide properly.
for example when switching spaces, switching Apps via CMD+Tab or a
system notification. former two could be fixed while keeping our current
blank cursor approach. though the notification case couldn't. there is
no event or similar to detect a notification and the cursor visibility
couldn't be recovered in any way.
new issues, i noticed that our event view isn't initialised yet when the
first VOCTRL_SET_CURSOR_VISIBILITY event gets dispatched, which depends
on the event view to be initialised. so the mouse cursor couldn't be
hidden when mpv was opened and the cursor was within the window bounds.
this wasn't noticeable before because of various bugs and unwanted
behavior that have been fixed with this. now, in case the event view
isn't ready yet, we set the visibility at a later point when the event
view is ready and a helper flag is set.
Fixes#1817#3856#4147
this fixes a small bug with black edges on live resize, due to the
synchronisation with the DisplayLink. we just pause the DisplayLink for
the duration of the live resize. i also added some convenience functions
for reoccurring calls and simplified some DisplayLink related screen
info.
since there are different views on what ontop is, we make the ontop
window level modifiable. at the moment only support for macOS was added.
the default for macOS was changed from 'system' to 'window' since this
fixes an unwanted behaviour in fullscreen and in general causes less
issues with expected behaviour.
Fixes#2376#3974
when the color profile was changed it used the right NSScreen but with
the old colorSpace. this was optimised out by a previous commit because
of a wrong assumption. we need to update the screen so we can get the
new colorSpace. this adds a bit of redundancy since on screen change it
will update screen pointer twice.
this optimises two things and fix a minor bug.
1. we always updated the display refresh rate on any mode change whether
it was the current screen or not. now we only update the refresh rate
when the mode changed happened on the current screen.
2. the windowDidChangeScreen event doesn't exclusively trigger on screen
changes so we updated the display refresh rate in cases where it wasn't
needed at all. since we manually keep track of the current screen, we
can easily test if the screen really changed.
3. weirdly on initWithContentRect accessing the screen of the window
always returned the main screen instead of the screen the window is
created on. since we already use the window init method with the screen
as argument, overwrite that method instead and use the screen argument.
we are dealing with several problems here, which weren't apparent
because we always initialised a new displaylink for the display refresh
rate retrieval, previously to commit 449eb20 and bug 9490b62.
just changing the display with CVDisplayLinkSetCurrentCGDisplay
can cause inconsistent refresh rates and discontinuity in timestamps.
this can either lead to bogus values for the Actual display refresh rate
or retrieving the refresh rate of the previous display if we immediately
try to get a new value. since the Actual refresh rate is computed i
assume that it at least needs one refresh period to actual return
something useful.
furthermore when changing the screen and updating the displaylink, it
seems that the retrieved refresh rates for the screen mpv wasn't opened
on are being estimated in a sub-optimal way. as an example, when moving
my window to my second screen the Actual refresh rate was always a
constant 60Hz, even though it is supposed to fluctuate a little bit.
though if mpv was started on the secondary screen the Actual refresh
rate fluctuated around 59.94Hz like expected. in that case my primary
screen always reported a constant 60Hz instead.
for the first problem we moved the actual retrieval of the refresh rate
to the very last moment when mpv actual requests a new value and not
when the refresh rate changed. we only update the displaylink itself
when a possible refresh rate change is detected. this gives the
displaylink some time to calculate the new refresh rate. for the second
problem, instead of setting the new display we completely uninitialise
the old dislaylink and create a new one for the new screen. this gives
us properly estimated refresh rates.
additionally we also optimised the display refresh rate fallback
heuristic. it will never be 0 anymore and we prevent it from returning
bogus values with a simple threshold for the difference of the Actual
and Nominal refresh rate.
setting a window level other than NSNormalWindowLevel always sets
NSWindowCollectionBehaviorTransient, which prevents certain things to
work properly. examples are automatic switching to the active Space when
mpv is made active and (de-)miniaturizing. latter always lead to a
vanishing window.
Fixes#1757#1884
everytime we switched to a new video file a new displaylink was
initialised and started, but the old one was not stopped and released
beforehand. this lead to several displaylink callback calls per swap,
depending on how many files were switched beforehand. moving the
displaylink init call to the cocoa init functions will ever only init
one displaylink.
Fixes#4031
we are calling the method on a NSWindow object that may not respond to
that call, since its a method of MpvVideoWindow. add the method to our
protocol and rename that protocol to reflect the change.
the display refresh rate can't be estimated
correctly in some cases and just increases till it
turns off display-resample. cases are
off-screen rendering (different space), mpv
being completely hidden behind another window or
the mission control view.
this utilise the unused displaylink callback to
limit the refresh rate to the actual display
refresh rate.
This flips the y-coordinate to be consistent with
other platforms and the manual. furthermore it
fixes an unwanted behaviour of the cocoa
convertRectFromBacking method, where the x- and
y-coordinate was divided by the same factor as the
width and height instead of placing the new scaled
rectangle at the same relative position as the
original unscaled rectangle, by manually
calculating the new position.
Fixes#3867
this replaces the old fullscreen with the native
macOS fullscreen. additional the
--fs-black-out-screens was removed since the new
API doesn't support it in a way the old one did.
it can possibly be re-added if done manually.
Fixes#2857#3272#1352#2062#3864
Deactivating this options makes it possible to
circumvent the default OS X behavior of using
points. Windows on HiDPI resolutions won't open
in double the size anymore and videos are display
in their native resolution when windowed.
Fixes#3716
The glFlush() call was made optional recently
since it's not needed in most cases. On OSX though
this is needed since we removed kCGLPFADoubleBuffer
from the context creation, so the glFlush() call
was added to the cocoa backend only.
The CGLFlushDrawable() call can be safely removed
since it only does something when a double
buffered context is used. Also fixes a small typo.
Fixes#3627.
Before this commit, all VOs had to toggle the option flag themselves,
now command.c does it.
I can't really comprehend why it required every VO to do this manually.
Maybe it was for rejecting the property/option change if the VO didn't
support a specific capability. But then it could have checked the VOCTRL
result. In any case, I don't care, and successfully changing the
property without doing anything (With some VOs) is fine too. Many things
work this way now, and it's simpler overall.
This change will be useful for cleaning up VO option handling.
1. this basically reverts commit de4c74e5a4.
even with CVDisplayLinkCreateWithActiveCGDisplays and
CVDisplayLinkSetCurrentCGDisplayFromOpenGLContext we still have to
explicitly set the current display ID, otherwise it will just always
choose the display with the lowest refresh rate. another weird thing is,
we still have to set the display ID another time with
CVDisplayLinkSetCurrentCGDisplay after the link was started. otherwise
the display period is 0 and the fallback will be used.
if we ever use the callback method for something useful it's probably
better to use CVDisplayLinkCreateWithActiveCGDisplays since we will need
to keep the display link around instead of releasing it at the end.
in that case we have to call CVDisplayLinkSetCurrentCGDisplay two times,
once before and once after LinkStart.
2. add windowDidChangeScreen delegate to update the display refresh rate
when mpv is moved to a different screen.
We have two problems here.
1. CVDisplayLinkGetActualOutputVideoRefreshPeriod, like the name suggests,
returns a frame period and not a refresh rate. using this as screen_fps
just leads to a slideshow. why didn't this break video playback on OS X
completely? the answer to this leads us to the second problem.
2. it seems that CVDisplayLinkGetActualOutputVideoRefreshPeriod always
returns 0 if used without CVDisplayLinkSetOutputCallback and hence always
fell back to CVDisplayLinkGetNominalOutputVideoRefreshPeriod. adding a
callback to CVDisplayLink solves this problem. the callback function at
this moment doesn't do anything but could possibly used in the future.
It always was a weird artifact - VOCTRLs are meant _not_ to require
special handling in the code that passes them through (like in vo.c).
Removing it is also interesting to further reduce the dependency of
backends on struct vo. Just get rid of it.
Removing it is somewhat inconvenient, because in many situations the UI
window is created after the first VOCTRL_UPDATE_WINDOW_TITLE. This means
these backends have to store it in a new field in their own context.
It doesn't have any real purpose anymore. Up until now, it was still
implemented by vo_wayland, but since we changed how the frame callbacks
work, even that appears to be pointless.
Originally, the plan was to somehow extend this mechanism to all
backends and to magically fix frame scheduling, but since we can't hope
for proper mechanisms even on wayland, this idea looks way less
interesting.
This fixes a regression since commit f4d62da8. The original code run
vo_cocoa_config_window() once without creating the window, which had the
effect that the last part of the function was run at least once before
the actual window was created. Fix the regression by moving it to before
the window is created.
The regression itself is hard to describe. One test case: start mpv from
a fullscreened terminal window. It should switch to another desktop,
with the mpv window visible. This didn't happen anymore.
Before this change, Cocoa state was accessed from both the VO and the
Cocoa main thread. This was probably not a good idea. There was some
locking as well as implicit synchronization using the dispatch
mechanism, but it wasn't watertight.
Change this completely. Now Cocoa things are always accessed from the
main thread only. The old mutex falls away, as well as the
vo_cocoa_set_current_context() function, which implicitly used the lock
to coordinate VO accesses. With the new code, the VO thread generally
has to wait for the main thread, while the main thread never waits for
the VO and rarely accesses it. Fortunately, this is rather straight
forward, and most of this is achieved by making vo_cocoa_control() run
on the main thread. The logic of the code does generally not change.
Some aspects are trickier. Apparently we can't access the
NSOpenGLContext from the VO thread, because this object is not thread-
safe. We use some CGLContextObj functions instead, such as for making
the context current and swapping the buffers.
Interrupt video timing. This means the Cocoa event loop does not have
to up to 2 video frame durations until redrawing the frame finally has
finished.
We abuse the VO event flags for this. Eventually this should use
wait_vo() or so in the video timing wait function, but for now the
interaction this would require with the code of other VOs/backends
would cause too much of a mess.
Instead of requiring a complicated mechanism to share the entire OpenGL
and renderer state between VO and Cocoa thread just to do the redrawing
during live-resize on the Cocoa thread, let the Cocoa thread wait on the
VO thread. This wil allow some major simplifications and cleanups in the
future.
One problem with this is that it can enter a deadlock whenever the VO
tries to sync with the Cocoa thread. To deal with this, the Cocoa thread
waits with a timeout. This can probably be improved later, though in
general this situation can always happen, unless the Cocoa thread waits
in a reentrant way.
Some other details aren't completely clean either. For example,
pending_events should be accessed atomically. This will also be fixed
later.
