| 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

| 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.

| const char* AVInputFormat::name |
A comma separated list of short names for the format.
New names may be appended with a minor bump.

| int(* AVInputFormat::read_close)(struct AVFormatContext *) |
Close the stream.
The AVFormatContext and AVStreams are not freed by this function
Referenced by avformat_close_input().
| int(* AVInputFormat::read_header)(struct AVFormatContext *) |
Read the format header and initialize the AVFormatContext structure.
Return 0 if OK. Only used in raw format right now. 'avformat_new_stream' should be called to create new streams.
Referenced by av_demuxer_open(), and avformat_open_input().
| int(* AVInputFormat::read_packet)(struct AVFormatContext *, AVPacket *pkt) |
Read one packet and put it in 'pkt'.
pts and flags are also set. 'avformat_new_stream' can be called only if the flag AVFMTCTX_NOHEADER is used and only in the calling thread (not in a background thread).
Referenced by ff_read_packet().
| int(* AVInputFormat::read_pause)(struct AVFormatContext *) |
Pause playing - only meaningful if using a network-based format (RTSP).
Referenced by av_read_pause().
| int(* AVInputFormat::read_play)(struct AVFormatContext *) |
Start/resume playing - only meaningful if using a network-based format (RTSP).
Referenced by av_read_play().
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_format3(), 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 avformat_seek_file(), open_input_stream(), seek_frame_generic(), and seek_frame_internal().
| int(* AVInputFormat::read_seek2)(struct AVFormatContext *s, int stream_index, int64_t min_ts, int64_t ts, int64_t max_ts, int flags) |
Seek 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) |
Get the next timestamp in stream[stream_index].time_base units.
