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 formatted data.

Returns

Newly allocated struct containing split data.

ASSDialog* ff_ass_split_dialog	(	ASSSplitContext *	ctx,
		const char *	buf,
		int	cache,

	)

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

	)

Split one ASS Dialogue line from a string buffer.

Parameters

ctx	Context previously initialized by ff_ass_split().
buf	String containing the ASS "Dialogue" line.

Returns

Parameters

callbacks	Set of callback functions called for each override code encountered.
priv	Opaque pointer passed to the callback functions.
buf	The ASS "Dialogue" Text field to split.

Returns

>= 0 on success otherwise an error code <0
