media: uapi: move HEVC stateless controls out of staging

2022-07-15T16:36:58+00:00

HEVC uAPI is used by 2 mainline drivers (Hantro, Cedrus) and at least 2 out-of-tree drivers (rkvdec, RPi). The uAPI has been reviewed so it is time to make it 'public' by un-staging it.

media: uapi: Change data_bit_offset definition

2022-07-15T16:36:58+00:00

'F.7.3.6.1 General slice segment header syntax' section of HEVC specification describes that a slice header always end aligned on byte boundary, therefore we only need to provide the data offset in bytes.

2022-07-15T16:36:58+00:00

The number of bits to skip in the slice header can be computed in the driver by using sps, pps and decode_params information. This makes it possible to remove Hantro dedicated control.

media: uapi: Add V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS control

2022-07-15T16:36:44+00:00

The number of 'entry point offset' can be very variable. Instead of using a large static array define a v4l2 dynamic array of U32 (V4L2_CTRL_TYPE_U32). The number of entry point offsets is reported by the elems field and in struct v4l2_ctrl_hevc_slice_params.num_entry_point_offsets field.

Make explicit that V4L2_CID_STATELESS_HEVC_SLICE_PARAMS control is a dynamic array control type. Some drivers may be able to receive multiple slices in one control to improve decoding performance.
