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.

Can use flags: AVFMT_NOFILE, AVFMT_NEEDNUMBER, AVFMT_SHOW_IDS, AVFMT_NOTIMESTAMPS, AVFMT_GENERIC_INDEX, AVFMT_TS_DISCONT, AVFMT_NOBINSEARCH, AVFMT_NOGENSEARCH, AVFMT_NO_BYTE_SEEK, AVFMT_SEEK_TO_PTS.

If extensions are defined, then no probe is done.

You should usually not use extension format guessing because it is not reliable enough

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.

Read the format header and initialize the AVFormatContext structure.

Return 0 if OK. 'avformat_new_stream' should be called to create new streams.

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).

Returns

0 on success, < 0 on error. Upon returning an error, pkt must be unreferenced by the caller.
