int64_t ff_vorbiscomment_length | ( | AVDictionary * | m, |
const char * | vendor_string | ||
) |
Calculate the length in bytes of a VorbisComment.
This is the minimum size required by ff_vorbiscomment_write().
m | The metadata structure to be parsed. For no metadata, set to NULL. |
vendor_string | The vendor string to be added into the VorbisComment. For no string, set to an empty string. |

int ff_vorbiscomment_write | ( | uint8_t ** | p, |
AVDictionary ** | m, | ||
const char * | vendor_string | ||
) |
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()
p | The buffer in which to write. |
m | The metadata struct to write. |
vendor_string | The vendor string to write. |
