When initialization failed, vo_lavc may cause an irrecoverable state in
the ffmpeg-related structs. Therefore, we reject additional
initialization attempts at least until we know a better way to clean up
the mess.
ao_lavc currently cannot be initialized more than once, yet it's good to
do consistent changes there as well.
Also, clean up uninit-after-failure handling to be less spammy.
This reverts commit d859549424.
Going to apply the alternative fix through PR #1256, which came just
some seconds after pushing the reverted commit. The reverted commit
was reported as not actually working.
This silences the warning:
video/out/gl_video.c:1091:51: runtime error: division by zero
when running with clang -fsanitize=undefined. Division by zero is legal
according to IEEE, but I guess clang doesn't care about standard. While
triggering this warning isn't actually avoided in all cases, it's
avoided in the common case and also makes people shut up about it.
XRRGetOutputInfo contains a "name" element which corresponds to to the
display names given to the user by the "xrandr" command line
utility. Copy it into the xrandr_display struct for each display.
On VOCTRL_GET_DISPLAY_NAMES, send a copy of the names
of the displays spanned by the mpv window on.
Instead, use the native-endian alias, and switch the wayland format
depending on the target platform's endian.
This drops support for swapped-endian formats, but I think that is ok.
Not only are the affected formats rather ancient and backwards, but
using swapped formats probably does not make any sense for performance
either.
Untested.
Add a generic mechanism to the VO to relay "extra" events from VO to
player. Use it to notify the core of window resizes, which in turn will
be used to mark all affected properties ("window-scale" in this case) as
changed.
(I refrained from hacking this as internal command into input_ctx, or to
poll the state change, etc. - but in the end, maybe it would be best to
actually pass the client API context directly to the places where events
can happen.)
NSDisableScreenUpdates came to hunt me in the end and when mpv was paused, it
did wait for a frame that never came (because of interaction with the live
resizing code)!
Apparently this is needed for correct 3D mode subtitles. In general,
it seems you need to duplicate the whole "GUI", so it's done for all
OSD elements.
This doesn't handle the "duplication" of the mouse pointer. Instead,
the mouse can be used for the top/left field only. Also, it's possible
that we should "compress" the OSD in the direction it's duplicated, but
I don't know about that.
Fixes#1124, at least partially.
In interlaced modes, we output fields, not complete frames, so the
framerate doubles.
The method to calculate this was borrowed from xrandr code.
Hopefully fixes#1224.
Apparently if resizing a NSWindow from a secondary thread Cocoa will
automatically protect itself using NSViewHierarchyLock and in our case,
cause a deadlock.
Fixes#1210
Especially with other components (libavcodec, OSX stuff), the thread
list can get quite populated. Setting the thread name helps when
debugging.
Since this is not portable, we check the OS variants in waf configure.
old-configure just gets a special-case for glibc, since doing a full
check here would probably be a waste of effort.
After removing synchronous libdispatch calls, this looks like it doesn't
deadlock anymore. I also experimented with pthread_mutex_trylock liek wm4
suggested, but it leads to some annoying black flickering. I will fallback to
that only if some new deadlocks are discovered.
As I understand, otherwise, the code will try to destroy the same
window again in the cleanup part of the gui_thread(), which makes no
sense and is potentially dangerous.
mp_stat() instead of stat() was used in the normal code (i.e. even
on Unix), because MinGW-w64 has an unbelievable macro-mess in place,
which prevents solving this elegantly.
Add some dirty workarounds to hide mp_stat() from the normal code
properly. This now requires replacing all functions that use the
struct stat type. This includes fstat, lstat, fstatat, and possibly
others. (mpv currently uses stat and fstat only.)
The previous commit was actually incorrect, and the change had
absolutely no effect. The two formats are (fortunately) the same. I'm
probably too tired.
This would have been wrong for hw decoders which pass us NV12 or NV21.
The format the GL shader filter chain gets is stored in p->image_desc,
while p->image_format still contains the "real" input format (which in
case of hw decoding is an opsque hw accel format). Since no hw decoder
did this, this is really just a theoretical fix and doesn't fix any
actual bugs.
Instead of letting the window-scale property return the old value until
X11 actually executed the resize, just set the new assumed internal
window size immediately. This avoids a "lag" between setting and reading
the window-scale property, like OSD controls typically do.
Remove the additional calls from vo_x11_highlevel_resize() - they're
pointless and slightly wrong, and resize events will take care of
updating these things correctly anyway.
Fixes#1176.
("window-scale" works via VOCTRL_[S|G]ET_UNFS_WINDOW_SIZE.)
This allows mpv's view to take key and send events to mpv's core.
To set key status correctly, clients must call -[NSWindow selectNextKeyView:]
during reconfig on the main thread. All is 'documented' in the cocoabasic
example.
If someone knows a better way to handle giving key to the embedded view,
let me know!
Objective-C categories need special linker flags from the user when statically
linking (-ObjC LDFLAG), so make everyone's life simpler and remove them.
This can hang if the window was destroyed externally (or that's what I
suspect happens), and we somehow didn't receive the DestroyNotify event.
I'm not sure why we wouldn't receive this event (since it should just be
in the xlib event queue), but on the other hand there's no real need to
wait for window destruction.
This essentially reverts 97fc74e2.
The one in msg.c was mistakenly removed with commit e99a37f6.
I didn't actually test the change in ao_sndio.c (but obviously "ap"
shouldn't be static).
Worryingly wrong. Fixes#1162.
Also fix another issue (window title was set anyway), which was why I
didn't notice this and testing it seemed to be fine.
