Philip Langdale 93febc4e15 avutil/hwcontext_vdpau: Correctly initialise pixfmts
The number of declared vdpau formats can vary depending on which
version of libvdpau we build against, so the number of pix fmts
can vary too. Let's make sure we keep those numbers in sync.

ManojGuptaBonda ed5ee04722 avcodec/hevcdec: Add VDPAU to list of supported formats
Added VDPAU to list of supported formats for HEVC10 and 12 bit formats
also added 42010 bit to surface_parameters and new VDP chroma formats to
VDPAUPixFmtMaps

Add HEVC 420 10/12 Bit  and 444 10/12 Bit support for VDPAU

YUV444P10 is defined as the 444 surface with 10bit valid data in LSBs
but H/w returns Data in MSBs Hence if we map output as YUV444p16 it
is filtering out the LSB to convert to p10 format.

ManojGuptaBonda d617d54efa avutil/hwcontext_vdpau: Map 444 pix fmts to new VdpYCbCr types
New VdpYCbCr Formats VDP_YCBCR_FORMAT_Y_U_V_444 and,
VDP_YCBCR_FORMAT_Y_UV_444 have been added in VDPAU with libvdpau-1.2
to be used in get/putbits for YUV 4:4:4 surfaces. Earlier mapping of
AV_PIX_FMT_YUV444P to VDP_YCBCR_FORMAT_YV12 is not valid.

Hence this Change maps AV_PIX_FMT_YUV444P to VDP_YCBCR_FORMAT_Y_U_V_444
to access the YUV 4:4:4 surface via read-back API's of VDPAU.

wm4 cbbb206734 hwcontext_vdpau: implement av_hwdevice_get_hwframe_constraints()
In addition, this does not allow creating frames contexts with sw_format
for which no known transfer formats exist. In theory, we should check
whether the chroma format (i.e. the sw_format) is supported at all by
the vdpau driver, but checking for transfer formats has the same effect.

Note that the pre-existing code adds 1 to priv->nb_pix_fmts[i] for
unknown reason, and some checks need to account for that to check for
empty lists. They are not off-by-one errors.
