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.

ASSDialog* ff_ass_split_dialog	(	ASSSplitContext *	ctx,
		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.

Parameters:

ctx

Context previously initialized by ff_ass_split().

int ff_ass_split_override_codes	(	const ASSCodesCallbacks *	callbacks,
		void *	priv,
		const char *	buf
	)

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

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

ASSStyle* ff_ass_style_get	(	ASSSplitContext *	ctx,
		const char *	style
	)

Find an ASSStyle structure by its name.

Parameters:

	ctx	Context previously initialized by ff_ass_split().
	style	name of the style to search for.

Returns:

the ASSStyle corresponding to style, or NULL if style can't be found
