437bc925f6 display: add display types.
Move display types from gstvaapipluginutil.* to gstvaapidisplay.* so that
we could simplify characterization of a GstVaapiDisplay. Also rename "auto"
type to "any", and add a "display-type" attribute.

411b970f8a display: use prefixed display names for cache lookups.
This improves display name comparisons by always allocating a valid display
name. This also helps to disambiguate lookups by name in the global display
cache, should a new backend be implemented.

8ef490a3de videobuffer: drop deprecated functions.

809a85433d videobuffer: mark video buffer creation routines as deprecated.
The vdeo buffer creation routines shall actually be internal to gstreamer-vaapi
plugin elements. So deprecate any explicit creation routines that are not the
new *_typed_new*() variants.

e12ef8e6a2 videobuffer: factor out base and GLX implementations.
Introduce new typed constructors internal to gstreamer-vaapi plugin elements.
This avoids duplication of code, and makes it possible to further implement
generic video buffer creation routines that automatically map to base or GLX
variants.

e52def4737 utils: fix gl_create_context() with parent context set.
If GLX window was created from a foreign Display, then that same Display shall
be used for subsequent glXMakeCurrent(). This means that gl_create_context()
will now use the same Display that the parent, if available.

This fixes cluttersink with the Intel GenX VA driver.

7a0382130f configure: drop check for --enable-vaapi-glx.
This flag is obsolete. It was meant to explicitly enable/disable VA/GLX API
support, or fallback to TFP+FBO if this API is not found. Now, we check for
the VA/GLX API by default if --enable-glx is set. If this API is not found,
we now default to use TFP+FBO.

Note: TFP+FBO, i.e. using vaPutSurface() is now also a deprecated usage and
will be removed in the future. If GLX rendering is requested, then the VA/GLX
API shall be used as it covers most usages. e.g. AMD driver can't render to
an X pixmap yet.

5975def8ab mpeg2: allocate dummy picture for first field based I-frame.
In P-pictures, prediction shall be made from the two most recently
decoded reference fields. However, when the first I-frame is a field,
the next field of the current picture could be a P-picture but only a
single field was decoded so far. In this case, create a dummy picture
with POC = -1 that will be used as reference.

Some VA drivers would error out if P-pictures don't have a forward
reference picture. This is true in general but not in this very specific
initial case.

75538bbc9b decoder: use POC to maintain the DPB.
Introduce a POC field in GstVaapiPicture so that to store simpler sequential
numbers. A signed 32-bit integer should be enough for 1 year of continuous

Use this new POC value to maintain the DPB, instead of 64-bit timestamps.

Always prefer PTS from the demuxer layer for GOP times. If this is invalid,
i.e. demuxer could not determine the PTS or the generated PTS is lower than
max PTS from past pictures, then try to fix it up based on the duration of

For picture PTS, simply use the GOP PTS formerly computed then use TSN to
reconstruct a current time. Also now handle wrapped TSN correctly.

ab94048ea0 decoder: fix double buffer free with some VA drivers.
vaRenderPicture() implicitly disposes VA buffers. Some VA drivers would
push the VA buffer object into a list of free buffers to be re-used. However,
reference pictures (and data) that was kept would explicitly release the VA
buffer object later on, thus possibly destroying a valid (re-used) object.

Besides, some other VA drivers don't support correctly the vaRenderPicture()
semantics for VA buffers disposal and would leak memory if there is no explicit
vaDestroyBuffer(). The temporary workaround is to explcitily destroy VA buffers
right after vaRenderPicture(). All VA drivers need to be aligned.

82dbd6f5be h264: complete any current picture decoder before SPS / PPS change.
This ensures the VA context is clear when the encoded resolution
changes. i.e. make sure older picture is decoded with the older
VA context before it changes.

830efb3fbd glib: map deprecated API to glib >= 2.32 equivalents.
GStaticMutex and GStaticRecMutex are now replaced with GMutex and
GRecMutex, which no longer require any prior call to g_thread_init().

fe791efc28 decoder: allocate proxy surface earlier.
This simplifies gst_vaapi_picture_output() to only update the presentation
timestamp and submit the proxy to the decoder for output.

399875ee86 decoder: fix memory leak of VA objects on exit.
On sequence end, if the last decoded picture is not output for rendering,
then the proxy surface is not created. In this case, the original surface
must be released explicitly to the context.

11d09495ea mpeg2: use GstAdapter to track input sequence.
This fixes possible memory leaks and improves performance by removing
some extra copies.

a79c7f9fa6 decoder: optimize slice data buffers initialization.
VA drivers may have a faster means to transfer user buffers to GPU
buffers than using memcpy(). In particular, on Intel Gen graphics, we
can use pwrite(). This provides for faster upload of bitstream and can
help higher bitrates.

vaapi_create_buffer() helper function was also updated to allow for
un-mapped buffers and pre-initialized data for buffers.
