Really use the motion event coordinates to propagate the "mouse-move"
event to upper layer, instead of those from a button event. Those are
technically the same though.
When we copy a buffer because we're moving it into VA-API memory, we
need to copy flags. Otherwise, interlaced YUV buffers from a capture
source (e.g. V4L2) don't get flagged as interlaced.

Allow implicit conversions to raw video formats, while still keeping
VA surfaces underneath. This allows for chaining the vaapipostproc
element to a software-only element that takes care of maps/unmaps.
e.g. xvimagesink.

Use pooled GstVaapiVideoMeta information, i.e. always allocate that on
video buffer allocation. Also optimize copy of additional metadata info
into the resulting video buffer: only copy the video cropping info and
the source surface proxy.

If no explicit output surface format is supplied try to keep the one
supplied through the sink pad caps. This avoids a useless copy, even
if things are kept in GPU memory.
This is a performance regression from git commit dfa70b9.
If only advanced deinterlacing is requested, i.e. deinterlacing is
the only active algorithm to apply with source and output surface
formats being the same, then make sure to enable VPP processing.
Otherwise, allow fallback to bob-deinterlacing with simple rendering
flags alteration.
Add a default decide_allocation() hook to GstVaapiPluginBase. The caps
feature argument can be used to force a bufferpool with a specific kind
of memory.
Add GST_VAAPI_VIDEO_BUFFER_POOL_ACQUIRE_FLAG_NO_ALLOC params flag that
can be used to disable early allocations of vaapi video metas on buffers,
thus delagating that to the bufferpool user.
Fix gst_vaapi_surface_proxy_copy() to copy the view-id element, thus
fixing random frames skipped when vaapipostproc element is used in
passthrough mode. In that mode, GstMemory is copied, thus including
the underlying GstVaapiVideoMeta and associated GstVaapiSurfaceProxy.
Default to I420 format for output surfaces so that to match the usual
GStreamer pipelines. Though, internally, we could still opt for NV12
surface formats, i.e. default format=ENCODED is a hint for that, thus
delegating the decision to the VA driver.
Use the new gst_caps_has_vaapi_surface() helper function to detect
whether the sink pad caps contain native VA surfaces, or not, i.e.
no raw video caps.
Also rename is_raw_yuv to get_va_surfaces to make the variable more
explicit as we just want a way to differentiate raw video caps from
VA surfaces actually.
The "discontinuity" tracking code, whereby lost frames are tentatively
detected, is inoperant if the sink pad buffer timestamps are not right
to begin with.
This is a temporary workaround until the following bug is fixed:
https://bugzilla.gnome.org/show_bug.cgi?id=734386
In order to make the discontinuity detection code useful, we need to
detect the lost frames in the history as early as the previous frame.
This is because some VA implementations only support one reference
frame for advanced deinterlacing.
In practice, turn the condition for detecting new frame that is beyond
the previous frame from field_duration*2 to field_duration*3, i.e.
nothing received for the past frame and a half because of possible
rounding errors when calculating the field-duration either in this
element (vaapipostproc), or from the upstream element (parser element).
This is a regression introduced with commit faefd62.

Introduce new gst_caps_has_vaapi_surface() helper function to detect
whether the supplied caps has VA surfaces. With GStreamer >= 1.2, this
implies a check for memory:VASurface caps features, and format=ENCODED
for earlier versions of GStreamer.
Simplify the creation and installation process of properties, by first
accumulating them into a g_properties[] array, and next calling into
g_object_class_install_properties().
Also add missing docs and flags to some properties.
Move code around in a more logical way. Introduce GST_VAAPISINK_CAST()
helper macro and use it wherever we know the object is a GstBaseSink or
any base class. Drop explicit initializers for values that have defaults
set to zero.
Introduce new backends vtable so that to have clean separation between
display dependent code and common base code. That's a "soft" separation,
we don't really need dedicated objects.

Support for X11 "synchronous" mode was never implemented, and was only
to be useful for debugging. Drop that altogether, that's not going to
be useful in practice.

Rendering with GLX in vaapisink is kind of useless nowadays, including
OpenGL related fancy effects. Plain VA/GLX interfaces are also getting
deprecated in favor of EGL, or more direct buffer sharing with actual
GL textures.
Should testing of interop with GLX be needed, one could still be using
the modern cluttersink or glimagesink elements.

Allow dynamic changes to the window, e.g. performed by the user, and
make sure to refresh its contents, while preserving aspect ratio.
In practice, Expose and ConfigureNotify events are tracked in X11
display mode by default. This occurs in a separte event thread, and
this is similar to what xvimagesink does. Any of those events will
trigger a reconfiguration of the window "soft" size, subsequently
the render-rect when necessary, and finally _expose() the result.
The default of handle_events=true can be changed programatically via
gst_x_overlay_handle_events().
Thanks to Fabrice Bellet for rebasing the patch.

The gst_vaapidecode_decode_loop() function is called within a separate
task to fetch and output all frames that were decoded so far. So, if
the decoder_loop_status is forcibly set to EOS when _finish() is called,
then we are bound to exist the task without submitting the pending
frames.
If the downstream element error'ed out, then the gst_pad_push() would
propagate up an error and so we will get it right for cutting off
_finish() early in that case.
This is a regression from 6003596.
https://bugzilla.gnome.org/show_bug.cgi?id=733897
Fixes a hang/race on shutdown where _decode_loop() had already completed
its execution and _finish() was waiting on a GCond for decode_loop()
to complete. Also fixes the possible race where _finish() is called
but _decode_loop() endlessly returns before signalling completion
iff the decoder instance returns GST_FLOW_OK.

Now that we always track the currently active video buffer, it is
not necessary to automatically increase its reference since this is
implicitly performed in ::show_frame() through the get_input_buffer()
helper from GstVaapiPluginBase class.
This is a regression from a26df80.
Rework the logics behind the configuration of an adequate bufferpool,
especially when OpenGL meta or additional capsfeatures are needed.
Besides, for GStreamer >= 1.4, the first capsfeatures that gets matched,
and that is not system memory, is now selected by default.
Make sure to propagate memory:VASurface capsfeature to srcpad caps
only for GStreamer >= 1.5 as the plug-in elements in GStreamer 1.4
core currently miss additional patches available in 1.5-git (1.6).
This is a temporary workaround.
