Function Documentation

ff_vorbis_update_metadata()

int ff_vorbis_update_metadata	(	AVFormatContext *	s,
		AVStream *	st,
		const uint8_t *	buf,
		int	size )

Parse Vorbis comments, add metadata to an AVStream.

This function also attaches the metadata to the next decoded packet as AV_PKT_DATA_STRINGS_METADATA

Note

The buffer will be temporarily modified by this function, so it needs to be writable. Furthermore it must be padded by a single byte (not counted in size). All changes will have been reverted upon return.
