Subject: [PATCH v8 00/17] Move HEVC stateless controls out of staging
This series aims to make HEVC uapi stable and usable for hardware
decoder. HEVC uapi is used by 2 mainlined drivers (Cedrus and Hantro)
and 2 out of the tree drivers (rkvdec and RPI).
version 8:
- Same than v7 but rebased on media_stage/master
This version has been tested with these branches:
- GStreamer: https://gitlab.freedesktop.org/benjamin.gaignard1/gstreamer/-/tree/HEVC_aligned_with_kernel_5.15
- Linux: https://gitlab.collabora.com/benjamin.gaignard/for-upstream/-/tree/HEVC_UAPI_V8
version 7:
- Apply Jernej patches for Cedrus about bit offset definition and
V4L2_CID_STATELESS_HEVC_SLICE_PARAMS being a dynamic array control.
- Based on media_tree/master
version 6:
- Add short_term_ref_pic_set_size and long_term_ref_pic_set_size
in v4l2_ctrl_hevc_decode_params structure.
- Change slice_pic_order_cnt type to s32 to match with PoC type.
- Set V4L2_CTRL_FLAG_DYNAMIC_ARRAY flag automatically when using
V4L2_CID_STATELESS_HEVC_SLICE_PARAMS control.
- Add a define for max slices count
- Stop using Hantro dedicated control.
With patches to decode 10-bits bitstream and produce P010 frames the Fluster score
which was 77/147 before, is now 141/147.
The 10-bits series will comes after this because of it dependency to
uAPI change. If you are curious you can find the WIP branch here:
https://gitlab.collabora.com/benjamin.gaignard/for-upstream/-/commits/WIP_HEVC_UAPI_V7
The 6 failing tests are:
- PICSIZE_{A,B,C,D}_Bossen_1 where resolutions are to big for Hantro hardware.
- WPP_D_ericsson_MAIN_2 and WPP_D_ericsson_MAIN10_2 are visually ok but some
difference exist on 5 decoded frames. Some pixels values are no the same
the very end of few lines.
version 6:
- Stop using Hantro dedicated control and compute the number
of bytes to skip inside the driver.
- Rebased on media_tree/master
version 5:
- Change __u16 pic_order_cnt[2] into __s32 pic_order_cnt_val in
hevc_dpb_entry structure
- Add defines for SEI pic_struct values (patch 4)
- Fix numbers of bits computation in cedrus_h265_skip_bits() parameters
- Fix num_short_term_ref_pic_sets and num_long_term_ref_pics_sps
documentation (patch 8)
- Rebased on v5-18-rc1
GStreamer H265 decoder plugin aligned with HEVC uAPI v5:
https://gitlab.freedesktop.org/benjamin.gaignard1/gstreamer/-/tree/HEVC_aligned_with_kernel_5.15
Version 4:
- Add num_entry_point_offsets field in struct v4l2_ctrl_hevc_slice_params
- Fix V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS name
- Initialize control V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS
- Fix space/tab issue in kernel-doc
- Add patch to change data_bit_offset definition
- Fix hantro-media SPDX license
- put controls under stateless section in v4l2-ctrls-defs.c
At the end fluster tests results on IMX8MQ is 77/147 for HEVC codec.
