Functions

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.

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.

void ff_ass_split_free (ASSSplitContext *ctx)

Free all the memory allocated for an ASSSplitContext.

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

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

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

Find an ASSStyle structure by its name.

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.
