ASSSplitContext* ff_ass_split ( const char * buf )

Split a full ASS file or a ASS header from a string buffer and store the split structure in a newly allocated context.

Parameters:

buf

String containing the ASS formated data.

Returns:: Newly allocated struct containing split data.

Parameters:

	ctx	Context previously initialized by ff_ass_split().
	buf	String containing the ASS "Dialogue" lines.
	cache	Set to 1 to keep all the previously split ASSDialog in the context, or set to 0 to free all the previously split ASSDialog.
	number	If not NULL, the pointed integer will be set to the number of split ASSDialog.

Returns:: Pointer to the first split ASSDialog.
