Mengkejiergeli Ba	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.

Mengkejiergeli Ba	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" Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1444>	2022-02-16 08:26:46 +00:00
Mengkejiergeli Ba	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.
