This adds the plumbing to support decoding HEVC, VP9 and AV1
streams into 10bit pixel formats, linear and compressed.
This has only been tested on SM8550 & SM8650 with HEVC, and was
inspired by Venus, DRM MSM and the downstream vidc driver for the
buffer calculations and HFI messages.
I was unable to get 10bit decoding working with ffmpeg since P010
support for v4l2 decoding is missing, but v4l2-ctl works with:
v4l2-ctl --verbose --set-fmt-video-out=pixelformat=HEVC --set-fmt-video=pixelformat=P010 --stream-mmap --stream-out-mmap --stream-from-hdr Big_Buck_Bunny_1080_10s_30MB_main10.h265.hdr --stream-to out.P010
v4l2-ctl --verbose --set-fmt-video-out=pixelformat=HEVC --set-fmt-video=pixelformat=Q10C --stream-mmap --stream-out-mmap --stream-from-hdr Big_Buck_Bunny_1080_10s_30MB_main10.h265.hdr --stream-to out.QC10
The non-10bit decoding still works as before.
With Big_Buck_Bunny_1080_10s_30MB reencoded in 10-bit profile
and tranformed in v4l2 header format with [1]:
ffmpeg -i Big_Buck_Bunny_1080_10s_30MB.h264 -pix_fmt yuv420p10le -c:v libx265 -crf 28 -x265-params profile=main10 Big_Buck_Bunny_1080_10s_30MB_main10.h265

Fluster HEVC results on SM8650:
./fluster.py run -ts JCT-VC-HEVC_V1 -d GStreamer-H.265-V4L2-Gst1.0 - 131/147
The failing test case:
- Pixel Format mismatch
- TSUNEQBD_A_MAIN10_Technicolor_2 - Gstreamer waits NV12 but decoder returns P010
- Unsupported resolution
- PICSIZE_A_Bossen_1 - resolution is higher than max supported
- PICSIZE_B_Bossen_1 - resolution is higher than max supported
- WPP_D_ericsson_MAIN_2 - resolution is lower than min supported
- WPP_D_ericsson_MAIN10_2 - resolution is lower than min supported
- CRC mismatch
- RAP_A_docomo_6
- CRC mismatch - bitstream issue - fails with ffmpeg sw decoder as well
- VPSSPSPPS_A_MainConcept_1

Changes in v2:
- Fixed bug breaking 8bit decoding
- Dropped filtering on G_FMT while waiting for soure change
- Dropped format filtering on ENUMFMT
- Switched ALIGN(x, 192) to roundup(x, 192) because ALIGN works only with Power Of Two numbers
- Cleaned and refactors the width/height/stride calculations
- Cleaned and redesigned the buffer calculations functions with proper comments and var names
- Passed fluster and v4l2-compliance to check for non regression
- Tested on SM8550
- Added missing V4L2_MPEG_VIDEO_HEVC_PROFILE_MAIN_10 with made gstreamer fail decoding
- Link to v1: https://patch.msgid.link/20260408-topic-sm8x50-iris-10bit-decoding-v1-0-428c1ec2e3f3@linaro.org

Fixed bug breaking 8bit decoding > - Dropped filtering on G_FMT while waiting for soure change > - Dropped format filtering on ENUMFMT > - Switched ALIGN(x, 192) to roundup(x, 192) because ALIGN works only with Power Of Two numbers > - Cleaned and refactors the width/height/stride calculations > - Cleaned and redesigned the buffer calculations functions with proper comments and var names > - Passed fluster and v4l2-compliance to check for non regression > - Tested on SM8550 > - Added missing V4L2_MPEG_VIDEO_HEVC_PROFILE_MAIN_10 with made gstreamer fail decoding > - Link to v1:
