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 7: - Apply Jernej patches for Cedrus about bit offset definition and V4L2_CID_STATELESS_HEVC_SLICE_PARAMS being a dynamic array control. 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. 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_V6 With patches to decode 10-bits bitstream and produce P010 frames the Fluster score which was 77/147 before, is now 138/147. 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_V6 The 9 failing tests are: - CONFWIN_A_Sony_1 which contains conformance_window_flag that isn't supported by the hardware (but visually ok aside a pixel shift). - PICSIZE_{A,B,C,D}_Bossen_1 where resolutions are to big for Hantro hardware. - TSKIP_A_MS_3 is ok when testing alone but fail (corrupted lines on the first frame) when running it after a couple of other tests. - VPSSPSPPS_A_MainConcept_1 where there is an issue on gst parser side because of VPS/SPS/PPS ordering - 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.
