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()
In buffer_alloc, if the buffer caps are new, call
gst_pad_peer_accept_caps once only, it's useless to call it in the
cases where we know it will always fail.
Fixes bug #621190
We know our plugins and examples are independent of each other, so may
just as well build them in parallel. Makes the output a bit messy, but
that shouldn't be a problem and can easily be avoided with make -j1.
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 ximagesink with handle-events=false and handle-expose=false then we can
avoid the extra thread.
Fix 'variable may be used uninitialized' compiler warning (which is
true in theory, but can't actually ever happen, since we always
call the function with check=FALSE).
Fixes#596313.
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.
Remove some useless debug info that reported wrong image sizes.
When upstream does not accept out suggested size, fall back to allocating an
image of the requested width/height instead of the currently configured size.
The problem is that an image is reused from the pool because the width/height
match but the caps on the new buffer are the requested caps with possibly
different height/width resulting in errors.

Original commit message from CVS:
* sys/ximage/ximagesink.c: (gst_ximagesink_ximage_new):
When XShm is not available, we might get row strides that are not
rounded up to multiples of four; this is bad, because virtually
every RGB-processing element in GStreamer assumes rowstrides are
rounded up to multiples of four, so let's allocate at least enough
memory to avoid crashes in this case. The image will still be
displayed distorted though if this happens, so that still needs
fixing (maybe by allocating a bigger image with an 'even' width
and then clipping it appropriately when rendering - something for
Xlib aficionados in any case).

Move some cleanup stuff from the state change handler into a _reset()
function that can be called from _finalize(). This ensures that things
get freed even if (for some reason) the NULL->READY state transition
fails in the parent class.
Even if a parent state change fails, process our downward state change
logic instead of bailing out early.
Free the correct xcontext pointer in ximagesink's xcontext_clear.

Handle RGB Xv formats properly by transforming them into our

Handle the case where the XServer has a different idea about the size

Use -1 to indicate 'no image format', because 0 is a valid XServer

Put RGB Xv formats at the end of the caps, so that we always prefer
YUV format frames.

height, and then return that in our caps.

I think one day i'll completely undestand how caps negotiation
is supposed to work. This refactoring handles buffer_alloc
called with caps we can't handle. We definitely don't want a

we would like to receive.

renegotiation
happens (only visible on ximagesink but bug is in xv too)
set_caps was
destroying the internal x[v]image used to memcpy non locally
alloced
buffers so that it got renewed on next _chain. The issue is that
_expose will try to put that image as it reffed it in _put.
Using gst_buffer_unref instead of destroy fixes it !
