944a7bd077 filter: add initial support for deinterlacing.
Add basic deinterlacing support, i.e. bob-deinterlacing whereby only
the selected field from the input surface is kept for the target surface.
Setting gst_vaapi_filter_set_deinterlacing() method argument to
GST_VAAPI_DEINTERLACE_METHOD_NONE means to disable deinterlacing.

Also move GstVaapiDeinterlaceMethod definition from vaapipostproc plug-in
to libgstvaapi core library.

1d222d3b4a filter: add support for color balance adjustment.

and contrast. The respective range for each filter shall be the same as

a854768a80 filter: add support for sharpening.
Sharpening is configured with a float value. The supported range is
-1.0 .. 1.0 with 0.0 being the default, and that means no sharpening
operation at all.

87c8d28499 filter: add helper functions.
Add helper functions to ensure an operation VA buffer is allocated to
the right size; that filter caps get parsed and assigned to the right
operation too; and that float parameters are correctly scaled to fit
the reported range from the VA driver.

Add gst_vaapi_video_format_from_string() helper function to convert from
a video format string representation to a suitable GstVideoFormat. This
is just an alias to gst_video_format_from_string() for GStreamer 1.0.x
builds, and a proper iteration over all GstVideoFormat string representations
otherwise for earlier GStreamer 0.10.x builds.

d8ffc2c150 libs: drop some public APIs.
Don't expose GstVaapiContext APIs and make them totally private to
libgstvaapi core library. That API would also tend to disappear in
a future revision. Likewise, don't expose GstVaapiDisplayCache API
but keep symbols visible so that the various render backends could
share a common display cache implementation in libgstvaapi.

Try to clean-up the documentation from any stale entry too.

1fff3a44dd decoder: fix memory leak when processing interlaced pictures.
Fix memory leak when processing interlaced pictures and that occurs
because the first field, represented as a GstVideoCodecFrame, never
gets released. i.e. when the picture is completed, this is generally
the case when the second field is successfully decoded, we need to
propagate the GstVideoCodecFrame of the first field to the original
GstVideoDecoder so that it could reclaim memory.

Otherwise, we keep accumulating the first fields into GstVideoDecoder
private frames list until the end-of-stream is reached. The frames
are eventually released there, but too late, i.e. too much memory
may have been consumed.

ac75755105 pool: fix deallocation of video pools.
The queue of free objects to used was deallocated with g_queue_free_full().
However, this convenience function shall only be used if the original queue
was allocated with g_queue_new(). This caused memory corruption, eventually
leading to a crash.

The correct solution is to pair the g_queue_init() with the corresponding
g_queue_clear(), while iterating over all free objects to deallocate them.

18031dc6ff surface: fix memory leak through unreleased parent context.
Break the circular references between GstVaapiContext and its children
GstVaapiSurfaces. Since the VA surfaces held an extra reference to the
context, which holds a reference to its VA surfaces, then none of those
were released.

How does this impact support for subpictures?

The only situation when the parent context needs to disappear is when
it is replaced with another one because of a resolution change in the
video stream for instance, or a normal destroy. In this case, it does
not really matter to apply subpictures to the peer surfaces since they
are either gone, or those that are left in the pipe can probably bear
a reinstantiation of the subpictures for it.

So, parent_context is set to NULL when the parent context is destroyed,
other VA surfaces can still get subpictures attached to them, individually
not as a whole. i.e. subpictures for surface S1 will be created from
active composition buffers and associated to S1, subpictures for S2 will
be created from the next active composition buffers, etc. We don't try
to cache the subpictures in those cases (pending surfaces until EOS
is reached, or pending surfaces until new surfaces matching new VA context
get to be used instead).
