Typedef Documentation

SwsOpFunc

typedef void(* SwsOpFunc) (const SwsOpExec *exec, const void *priv, int bx_start, int y_start, int bx_end, int y_end)

Process a given range of pixel blocks.

Note: bx_start and bx_end are in units of SwsCompiledOp.block_size.

ff_sws_ops_compile()

int ff_sws_ops_compile	(	SwsContext *	ctx,
		const SwsOpBackend *	backend,
		const SwsOpList *	ops,
		SwsCompiledOp *	out
	)

Attempt to compile a list of operations using a specific backend, or the best available backend if backend is NULL.

Returns 0 on success, or a negative error code on failure.

Definition at line 93 of file ops_dispatch.c.

Referenced by check_ops(), and compile().

ff_sws_compile_pass()

int ff_sws_compile_pass	(	SwsGraph *	graph,
		const SwsOpBackend *	backend,
		SwsOpList **	ops,
		int	flags,
		SwsPass *	input,
		SwsPass **	output
	)

Resolves an operation list to a graph pass.

The first and last operations must be a read/write respectively.

Parameters

backend	Force the use of a specific backend (Optional)
ops	Operations to compile. Ownership passes to this function, and will be set to NULL, even on failure.
flags	Set of SwsOpCompileFlags
input	The input for the compiled passes. (Optional)
output	The resulting final output pass will be stored here. If NULL, no output passes are created, and any compiled functions are instead immediately freed.
