bbbf3741ff h264: introduce new frame store structure.
The frame store represents a Decoded Picture Buffer entry, which can
hold up to two fields. So far, the frame store is only used to hold
full frames.

afddf11e22 h264: minor clean-ups.
Move DPB flush up if the current picture to decode is an IDR. Besides,
don't bother to check for IDR pictures in dpb_add() function since an
explicit DPB flush was already performed in this case.

d180a3a9f6 h264: simplify reference picture marking process.
... to build the short_ref[] and long_ref[] lists from the DPB, instead
of maintaining them separately. This avoids refs/unrefs while making it
possible to generate the list based on the actual picture structure.

This also ensures that the list of generated ReferenceFrames[] actually
matches what reference frames are available in the DPB. i.e. short_ref[]
and long_ref[] entries are implied from the DPB, so there is no risk of
having "dangling" references.

3480fcc8d7 h264: introduce per-field POC in GstVaapiPictureH264.
Use the POC member available in the GstVaapiPicture base class and
get rid of the dependency on the local VAPictureH264 TopFieldOrderCnt
and BottomFieldOrderCnt. Rather, use a simple field_poc[] array
initialized to INT_MAX, so that to simplify picture POC calculation
for non frame pictures.

e30a518267 h264: fix activation order of picture and sequence parameters.
Delay ensure_context() until we actually need a VA context for allocating
new VA surfaces, and then GstVaapiPictures, but also when a real activation
of a new picture parameter set occurs, thus also implying an activation
of the related sequence parameter set.

The most important thing was to drop the global pps and sps pointers since
they may not have matched the currently activated picture parameter or
sequence parameter sets at the specified decode point.

Anoter positive side-effect is that this cleans up all occurrences of
decode_current_picture() to only keep those useful in decode_picture(),
before a new picture is allocated, or in decode_sequence_end() when
an end-of-stream or end-of-sequence condition occurred.

available in the bitstream.

to parse does not have the minimum required size. So, we can also

or with a size equals to zero. In this case, that buffer is simply
skipped and the function returns TRUE. A NULL buffer argument still

5db2e93d3c utils: fix build with <GL/glext.h> version >= 85.
Mesa recently updated the <GL/glext.h> header version to Khronos version 85.
This caused the PFNGLMULTITEXCOORD2FPROC definition to be moved out of the
GL_VERSION_1_3_DEPRECATED block. However, since <GL/gl.h> also defines
GL_VERSION_1_3 to 1, the definitions in <GL/glext.h> are then not enabled,
thus leaving PFNGLMULTITEXCOORD2FPROC undefined as well.

newer versions of the <GL/glext.h> header.

The former mode implies that a VA surface used for rendering can't be

The latter mode implies that the VA surface is implicitly copied to an

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.

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.

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.
