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.
