These properties are used for support of tile encoding. We just
support uniform mode of tile encoding, that is, separating picture
equally by (num-tile-cols X num-tile-rows).
According to HEVC spec A1, the max number of tiles in column is 20
and in rows is 22, so add two constant definitions.

We need to use the chroma_format_idc as the index for getting the
SubWidthC and SubHeightC values as the spec 6.1(table 6-1) defines.
The wrong SubWidthC or SubHeightC make us calculate a wrong right
or bottom offset for crop size and generate garbage in output.

Since bufferproxy and surface are not referenced circularly, there's
no need to keep, in the buffer proxy, a reference to the GstMemory
where it is held. This patch removes that handling.
The bufferproxy may reference the surface and the surface may also
reference the bufferproxy, producing a circular reference, which might
lead to serious resource leak problems.
Now make the relationship clearer, the bufferproxy's references is
transfered to surface, while bufferproxy just keeps the surface's
address without increasing its reference count.
The surface can be created through a bufferproxy like in
gst_vaapi_surface_new_with_dma_buf_handle(), and the surface might
get its bufferproxy via gst_vaapi_surface_get_dma_buf_handle(). In
both cases the surface holds a bufferproxy's reference.
This fixed segfault when running the pipeline below with iHD driver

In hevc, we can consider the -intra profile a subset of the none
-intra profile. The -intra profiles just contain I frames and we
definitely can use the none -intra profiles's context to decode
them.

This is a workaround for intel-media-driver bug
https://github.com/intel/media-driver/issues/865
The driver will force the RC method to CBR for HEVCe
when it parses the HRD param. Thus, any RC method
param submitted "prior" to the HRD param will be lost.
Therefore, VBR, ICQ and QVBR for HEVCe can't be
effectively enabled if the RC method param "precedes"
the HRD param.
To work around this issue, set the HRD param before
the RC method param so the driver will parse the RC
method param "after" the HRD param.
Afaict, other codecs in the driver (and other drivers)
do not appear to be dependent on the order of HRD and
RC param submission.
GstVaapiPixmap is an abstract base class which only implementation
were GstVaapiPixmapX11. This class were used for a special type of
rendering in the tests apps, utterly unrelated in GStreamer.
Since gstreamer-vaapi is no longer a general-user wrapper for VA-API
we should remove this unused API.
This removal drops libxrender dependency.
If the dependent_slice_segment_flag is true, most slice info derived from last slice.
So we need check the slice type after we call populate_dependent_slice_hdr
Since commit 32bf6f1e GLTextureUpload is broken because i965
doesn't report properly RGBA support. It could be possible to use RGBx
but GLTextureUpload only regotiates RGBA.
The simplest fix to this regression is adding synthetically the RGBA
format in the internal format map.
Instead of break at the fist foud quirk in the table, iterate all over
so it would be feasible to add several quirks for one driver per
element in array.
The intel-media-driver (iHD) can't convert output color
primaries when doing YUV to/from RGB CSC. Thus, we must
keep the output color primaries the same as the input
color primaries for this case.

When creating surfaces it is possible to pass to VA hints of its usage,
so the driver may do some optimizations.
This commit adds the handling of encoding/decoding hints.
