Data Fields | |
| const char * | name |
| const char * | long_name |
| Descriptive name for the format, meant to be more human-readable than name. | |
| int | priv_data_size |
| Size of private data so that it can be allocated in the wrapper. | |
| int(* | read_probe )(AVProbeData *) |
| Tell if a given file has a chance of being parsed as this format. | |
| int(* | read_header )(struct AVFormatContext *, AVFormatParameters *ap) |
| Read the format header and initialize the AVFormatContext structure. | |
| int(* | read_packet )(struct AVFormatContext *, AVPacket *pkt) |
| Read one packet and put it in 'pkt'. | |
| int(* | read_close )(struct AVFormatContext *) |
| Close the stream. | |
| int(* | read_seek )(struct AVFormatContext *, int stream_index, int64_t timestamp, int flags) |
| Seek to a given timestamp relative to the frames in stream component stream_index. | |

| Gets the next timestamp in stream[stream_index].time_base units. | |
| int | flags |
| Can use flags: AVFMT_NOFILE, AVFMT_NEEDNUMBER. | |
| const char * | extensions |
| If extensions are defined, then no probe is done. | |
| int | value |
| General purpose read-only value that the format can use. | |
| int(* | read_play )(struct AVFormatContext *) |
| Starts/resumes playing - only meaningful if using a network-based format (RTSP). | |
| int(* | read_pause )(struct AVFormatContext *) |
| Pauses playing - only meaningful if using a network-based format (RTSP). | |
| struct AVCodecTag *const * | codec_tag |
| int(* | read_seek2 )(struct AVFormatContext *s, int stream_index, int64_t min_ts, int64_t ts, int64_t max_ts, int flags) |
| Seeks to timestamp ts. | |

struct AVCodecTag* const* AVInputFormat::codec_tag [read] |
Definition at line 359 of file avformat.h.
| const char* AVInputFormat::extensions |
If extensions are defined, then no probe is done.
You should usually not use extension format guessing because it is not reliable enough

Can use flags: AVFMT_NOFILE, AVFMT_NEEDNUMBER.

| const char* AVInputFormat::long_name |
Descriptive name for the format, meant to be more human-readable than name.
You should use the NULL_IF_CONFIG_SMALL() macro to define it.

Size of private data so that it can be allocated in the wrapper.

Referenced by av_open_input_stream().
| int(* AVInputFormat::read_close)(struct AVFormatContext *) |
Close the stream.
The AVFormatContext and AVStreams are not freed by this function
Referenced by av_close_input_stream().
| int(* AVInputFormat::read_header)(struct AVFormatContext *, AVFormatParameters *ap) |
Read the format header and initialize the AVFormatContext structure.
Return 0 if OK. 'ap' if non-NULL contains additional parameters. Only used in raw format right now. 'av_new_stream' should be called to create new streams.
Referenced by av_open_input_stream().
| int(* AVInputFormat::read_packet)(struct AVFormatContext *, AVPacket *pkt) |
Read one packet and put it in 'pkt'.
pts and flags are also set. 'av_new_stream' can be called only if the flag AVFMTCTX_NOHEADER is used.
Referenced by av_read_packet().
| int(* AVInputFormat::read_pause)(struct AVFormatContext *) |
Pauses playing - only meaningful if using a network-based format (RTSP).
Referenced by av_read_pause().
| int(* AVInputFormat::read_play)(struct AVFormatContext *) |
Starts/resumes playing - only meaningful if using a network-based format (RTSP).
Referenced by av_read_play().
| int(* AVInputFormat::read_probe)(AVProbeData *) |
Tell if a given file has a chance of being parsed as this format.
The buffer provided is guaranteed to be AVPROBE_PADDING_SIZE bytes big so you do not have to check for that unless you need more.
Referenced by av_probe_input_format2(), and probe().
| int(* AVInputFormat::read_seek)(struct AVFormatContext *, int stream_index, int64_t timestamp, int flags) |
Seek to a given timestamp relative to the frames in stream component stream_index.
| stream_index | Must not be -1. | |
| flags | Selects which direction should be preferred if no exact match is available. |
Referenced by av_seek_frame(), av_seek_frame_generic(), avformat_seek_file(), and open_input_stream().
| int(* AVInputFormat::read_seek2)(struct AVFormatContext *s, int stream_index, int64_t min_ts, int64_t ts, int64_t max_ts, int flags) |
Seeks to timestamp ts.
Seeking will be done so that the point from which all active streams can be presented successfully will be closest to ts and within min/max_ts. Active streams are all streams that have AVStream.discard < AVDISCARD_ALL.
Referenced by avformat_seek_file().
| int64_t(* AVInputFormat::read_timestamp)(struct AVFormatContext *s, int stream_index, int64_t *pos, int64_t pos_limit) |
Gets the next timestamp in stream[stream_index].time_base units.
