Detailed Description

struct v4l2_h264_dpb_entry - H264 decoded picture buffer entry

@reference_ts: timestamp of the V4L2 capture buffer to use as reference. The timestamp refers to the timestamp field in struct v4l2_buffer. Use v4l2_timeval_to_ns() to convert the struct timeval to a __u64. @pic_num: matches PicNum variable assigned during the reference picture lists construction process. @frame_num: frame identifier which matches frame_num syntax element. @fields: indicates how the DPB entry is referenced. Valid values are V4L2_H264_{}_REF. @reserved: padding field. Should be zeroed by applications. @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. @flags: see V4L2_H264_DPB_ENTRY_FLAG_{}.
