ff_vorbiscomment_write()

int ff_vorbiscomment_write	(	uint8_t **	p,
		AVDictionary **	m,
		const char *	vendor_string,
		AVChapter **	chapters,
		unsigned int	nb_chapters
	)

Write a VorbisComment into a buffer.

The buffer, p, must have enough data to hold the whole VorbisComment. The minimum size required can be obtained by passing the same AVDictionary and vendor_string to ff_vorbiscomment_length()

Parameters

p	The buffer in which to write.
m	The metadata struct to write.
vendor_string	The vendor string to write.
chapters	The chapters to write.
nb_chapters	The number of chapters to write.
