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

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::extensions |
If extensions are defined, then no probe is done.
You should usually not use extension format guessing because it is not reliable enough

int(* AVInputFormat::read_probe) (const 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.

int(* AVInputFormat::read_header) (struct AVFormatContext *) |
Read the format header and initialize the AVFormatContext structure.
Return 0 if OK. 'avformat_new_stream' should be called to create new streams.

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).

int(* AVInputFormat::read_close) (struct AVFormatContext *) |
Close the stream.
The AVFormatContext and AVStreams are not freed by this function

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. |
Definition at line 732 of file avformat.h.
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.

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.
