 @Cast(value="int64_t*")
public LongPointer cur_frame_end()

key_frame

public int key_frame()

Set by parser to 1 for key frames and 0 for non-key frames. It is initialized to -1, so if the parser doesn't set this flag, old-style fallback using AV_PICTURE_TYPE_I picture type as key frames will be used.

key_frame

public AVCodecParserContext key_frame(int setter)

convergence_duration

@Cast(value="int64_t")
 @Deprecated
public long convergence_duration()

Deprecated. unused

convergence_duration

public AVCodecParserContext convergence_duration(long setter)

dts_sync_point

public int dts_sync_point()

Synchronization point for start of timestamp generation. Set to >0 for sync point, 0 for no sync point and <0 for undefined (default). For example, this corresponds to presence of H.264 buffering period SEI message.

dts_sync_point

public AVCodecParserContext dts_sync_point(int setter)

dts_ref_dts_delta

public int dts_ref_dts_delta()

Offset of the current timestamp against last timestamp sync point in units of AVCodecContext.time_base. Set to INT_MIN when dts_sync_point unused. Otherwise, it must contain a valid timestamp offset. Note that the timestamp of sync point has usually a nonzero dts_ref_dts_delta, which refers to the previous sync point. Offset of the next frame after timestamp sync point will be usually 1. For example, this corresponds to H.264 cpb_removal_delay.

dts_ref_dts_delta

public AVCodecParserContext dts_ref_dts_delta(int setter)

pts_dts_delta

public int pts_dts_delta()

Presentation delay of current frame in units of AVCodecContext.time_base. Set to INT_MIN when dts_sync_point unused. Otherwise, it must contain valid non-negative timestamp delta (presentation time of a frame must not lie in the past). This delay represents the difference between decoding and presentation time of the frame. For example, this corresponds to H.264 dpb_output_delay.

pts_dts_delta

public AVCodecParserContext pts_dts_delta(int setter)

@Cast(value="int64_t")
public long cur_frame_pos(int i)

field_order

public AVCodecParserContext field_order(int setter)

@Cast(value="AVPictureStructure")
public int picture_structure()

Indicate whether a picture is coded as a frame, top field or bottom field. For example, H.264 field_pic_flag equal to 0 corresponds to AV_PICTURE_STRUCTURE_FRAME. An H.264 picture with field_pic_flag equal to 1 and bottom_field_flag equal to 0 corresponds to AV_PICTURE_STRUCTURE_TOP_FIELD.

picture_structure

public AVCodecParserContext picture_structure(int setter)

output_picture_number

public int output_picture_number()

Picture number incremented in presentation or output order. This field may be reinitialized at the first picture of a new sequence. For example, this corresponds to H.264 PicOrderCnt.
