7d1b583d91 vaapidecode: fix compiler warnings.
Don't care of the return value for gst_vaapi_decoder_put_buffer()
during destruction of the element. Don't print out (uninitialised)
error code when allocation of video buffer failed.

2e8949d77b h264: add flag to compile with strict DPB ordering mode.
Allow build with strict DPB ordering mode whereby evicted entries
are replaced by the next entries, in order instead of optimizing
it away with the last entry in the DPB.

This is only useful for debugging purpose, against a reference SW
decoder for example.

26b7c46eda h264: drop extra code covered by built-in codecparsers.
GstH264SliceHdr.n_emulation_prevention_bytes is bound to exist now that
a newer version of codecparsers/ are used if the system provided one is
now recent enough to have those required extensions.

91da4fcb18 mpeg2: fix memory leak of empty packets.
Fix memory leakage of empty packets, i.e. packets that only contain
the start code prefix. In particular, free empty user-data packets.

Besides, the codec parser will already fail gracefully if the packet
to parse does not have the minimum required size. So, we can also
completely drop the block of code that used to handle packets of size 4
(including the start code).

8f7d19f010 mpeg2: fix return value for "no-data" conditions.
Fix return value when the second scan for start code fails. This means
there is not enough data to determine the full extents of the current
packet and the function shall return GST_VAAPI_DECODER_STATUS_ERROR_NO_DATA
in this case, instead of GST_VAAPI_DECODER_STATUS_SUCCESS.

86981eea41 decoder: refine semantics of gst_vaapi_decoder_put_buffer().
Improve the semantics for gst_vaapi_decoder_put_buffer() when an empty
buffer is passed on. An empty buffer is a buffer with a NULL data pointer
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
marks the end-of-stream.

set_fullscreen vfunc on GstVaapiWindow and then set the shell surface
fullscreen on not depending on that.

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.

Provide a PFNGLMULTITEXCOORD2FPROC replacement as an interim solution for
newer versions of the <GL/glext.h> header.

dde9232e10 h264: exclusively use GstAdapter, drop sub-buffer hack.
Maintaining the sub-buffer is rather suboptimal especially since we
were also maintaining a GstAdapter. Now, we only use the GstAdapter
thus requiring minor extra parsing when receiving avcC buffers.

5549dbc3c0 vaapidecode: don't reset decoder if codec type is the same.
Reset, i.e. destroy then create, the decoder in _setcaps() handler only
if the underlying codec type actually changed. This makes it possible
to be more tolerant with certain MPEG-2 streams that get parsed to
form caps that are compatible with the previous state but minor changes
to "codec-data".

Previously, vaapidecode would wait up to one second until a free surface

last decoded surface was to be presented, plus one second. Besides, end
times are now expressed relative to the monotonic clock.
