Split one or several ASS "Dialogue" lines from a string buffer and store them in an already initialized context.

Parameters
ctxContext previously initialized by ff_ass_split().
bufString containing the ASS "Dialogue" lines.
cacheSet to 1 to keep all the previously split ASSDialog in the context, or set to 0 to free all the previously split ASSDialog.
numberIf not NULL, the pointed integer will be set to the number of split ASSDialog.
Returns
Pointer to the first split ASSDialog.

Parameters
ctxContext previously initialized by ff_ass_split().
bufString containing the ASS "Dialogue" line.
Returns

privOpaque pointer passed to the callback functions.
bufThe ASS "Dialogue" Text field to split.
Returns
>= 0 on success otherwise an error code <0
