v4l2_ctrl_h264_decode_params Struct Reference

Detailed Description

struct v4l2_ctrl_h264_decode_params - H264 decoding parameters

@dpb: decoded picture buffer. @nal_ref_idc: slice header syntax element. @frame_num: slice header syntax element. @top_field_order_cnt: matches TopFieldOrderCnt picture value. @bottom_field_order_cnt: matches BottomFieldOrderCnt picture value. Note that picture field is indicated by v4l2_buffer.field. @idr_pic_id: slice header syntax element. @pic_order_cnt_lsb: slice header syntax element. @delta_pic_order_cnt_bottom: slice header syntax element. @delta_pic_order_cnt0: slice header syntax element. @delta_pic_order_cnt1: slice header syntax element. @dec_ref_pic_marking_bit_size: size in bits of dec_ref_pic_marking() syntax element. @pic_order_cnt_bit_size: size in bits of pic order count syntax. @slice_group_change_cycle: slice header syntax element. @reserved: padding field. Should be zeroed by applications. @flags: see V4L2_H264_DECODE_PARAM_FLAG_{}.
