1fe5655c2a msdkdec: Decoder should use its own pool when downstream allocator is not recognizable
Msdkdec should use it own pool when the allocation from downstream query
is not any msdk_allocator (i.e. msdk_video_allocator,
msdk_dmabuf_allocator and msdk_system_allocator). Otherwise, when using
pipeline "msdkh264dec ! vah264enc !" to transcode a not 16-bit-aligned
stream (i.e. 1920x1080), the transcoding will fail due to the size
mismatch issue between decoder pool and encoder pool.

586dfab9bd msdkdec: Enable SFC scaling for AVC and HEVC
Decoder SFC only supports down-scaling at most to 1/8.
For example, given a 4K bistream, SFC can scale it to 1080p via:
"msdkh265dec ! video/x-raw,width=1920,height=1080 ! glimagesink"

eb742c8ed0 msdkdec: Add SFC codes
SFC refers to Scaler Format Converter, more details here:
https://01.org/sites/default/files/documentation/intel-gfx-prm-osrc-kbl-vol15-sfc.pdf
By attaching mfxExtDecVideoProcessing buffer to mfxVideoParam, decoder
can do SFC for csc and scaling.

MSDK will check if surface bitdepth equals to input when no SFC is
triggered, which means in the case of SFC, there is no need to update
surface bitdepth via gst_msdk_update_mfx_frame_info_from_mfx_video_param.
