		const char *	buf,
		int	cache,
		int *	number
	)

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

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.

		void *	priv,
		const char *	buf
	)

Split override codes out of a ASS "Dialogue" Text field.

Parameters
