Improve bufferpool handling in ximagesink.
Implement bufferpool handling on xvimagesink.
Based on patches from benjamin gaignard <benjamin.gaignard@linaro.org>
Leave dealing with the appearance of the window when we are not playing to the
applications. We anyway want to go to NULL as quickly as possible.
Fixes#635800
And deprecate the gulong versions. This is to support platforms
where sizeof(unsigned long) < sizeof(void *). Fixes#627565.
API: Add gst_x_overlay_set_window_handle()
API: Deprecate: gst_x_overlay_set_xwindow_id()
API: Add gst_x_overlay_got_window_handle()
API: Deprecate: gst_x_overlay_got_xwindow_id()
API: Add GstXOverlay::set_window_handle()
API: Deprecate: GstXOverlay::set_xwindow_id()
Don't make libgstinterfaces (and thus libgstaudio etc.) indirectly depend
on libgstvideo by using the GstVideoRectangle helper structure in the API,
which causes undesirable dependencies, esp. with the gobject-introspection
(people will point and laugh at us if they find out that libgstaudio
depends on libgstvideo). Instead, pass the x, y, width and height parameters
directly to the function.
Re-fixes #610249.
Previously we hardcoded the target rectangle passes to Xv(Shm)PutImage. Extend
the implementation to use a full rectangle and don't assume 0,0 for top,left.
We can update the geometry in ConfigureNotify (unless we disable event-
handling). If event handling is disabled, one should use _expose() to trigger a
redraw and update the geometry.
The event thread is doing 20 wakeups per second to poll the events. If one runs
xvimagesink with handle-events=false and handle-expose=false then we can avoid
the extra thread.
According to the drivers in http://cgit.freedesktop.org/xorg/driver/ we should
format the colorkey depending on xcontext->depth. This is what they will use to
interprete the value. The max_value in turn is usualy a constant regardless of
the depth.
Calling clear at that transition does things like stopping xvideo (which is not
running at that time) and also clearing anything what the application might have drawn.
This breaks handle-expose and autopaint-colorkey features.
Original commit message from CVS:
* sys/ximage/ximagesink.c: (gst_ximagesink_buffer_alloc):
* sys/xvimage/xvimagesink.c: (gst_xvimagesink_buffer_alloc):
Clear all flags on buffers returned from the image pool.
Fixes#563143
