[−][src]Struct ffmpeg_sys_next::AVCodecParserContext
Fields
priv_data: *mut c_void
parser: *mut AVCodecParser
frame_offset: i64
cur_offset: i64
next_frame_offset: i64
pict_type: c_int
repeat_pict: c_int
This field is used for proper frame duration computation in lavf. It signals, how much longer the frame duration of the current frame is compared to normal frame duration.
frame_duration = (1 + repeat_pict) * time_base
It is used by codecs like H.264 to display telecined material.
pts: i64
dts: i64
last_pts: i64
last_dts: i64
fetch_timestamp: c_int
cur_frame_start_index: c_int
cur_frame_offset: [i64; 4]
cur_frame_pts: [i64; 4]
cur_frame_dts: [i64; 4]
flags: c_int
offset: i64
< byte offset from starting packet start
cur_frame_end: [i64; 4]
key_frame: c_int
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.
convergence_duration: i64
@deprecated unused
dts_sync_point: c_int
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_ref_dts_delta: c_int
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.
pts_dts_delta: c_int
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.
cur_frame_pos: [i64; 4]
Position of the packet in file.
Analogous to cur_frame_pts/dts
pos: i64
Byte position of currently parsed frame in stream.
last_pos: i64
Previous frame byte position.
duration: c_int
Duration of the current frame. For audio, this is in units of 1 / AVCodecContext.sample_rate. For all other types, this is in units of AVCodecContext.time_base.
field_order: AVFieldOrder
picture_structure: AVPictureStructure
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.
output_picture_number: c_int
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.
width: c_int
Dimensions of the decoded video intended for presentation.
height: c_int
coded_width: c_int
Dimensions of the coded video.
coded_height: c_int
format: c_int
The format of the coded data, corresponds to enum AVPixelFormat for video and for enum AVSampleFormat for audio.
Note that a decoder can have considerable freedom in how exactly it decodes the data, so the format reported here might be different from the one returned by a decoder.
