int avpriv_split_xiph_headers ( uint8_t extradata,
int  extradata_size,
int  first_header_size,
uint8_t header_start[3],
int  header_len[3] 
)

Split a single extradata buffer into the three headers that most Xiph codecs use.

(e.g. Theora and Vorbis) Works both with Matroska's packing and lavc's packing.

Parameters:
[in] extradata The single chunk that combines all three headers
[in] extradata_size The size of the extradata buffer
[in] first_header_size The size of the first header, used to differentiate between the Matroska packing and lavc packing.
[out] header_start Pointers to the start of the three separate headers.
[out] header_len The sizes of each of the three headers.
Returns:
On error a negative value is returned, on success zero.
