int ff_vorbiscomment_write ( uint8_t **  p,
AVDictionary **  m,
const char *  vendor_string 
)

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
pThe buffer in which to write.
mThe metadata struct to write.
vendor_stringThe vendor string to write.
