ff_thread_progress_init()

av_cold int ff_thread_progress_init	(	ThreadProgress *	pro,
		int	init_mode )

Initialize a ThreadProgress.

Parameters

init_mode

If zero, the ThreadProgress will be initialized to be in no-op mode as described above. Otherwise it is initialized to be in ordinary mode.

ff_thread_progress_destroy()

av_cold void ff_thread_progress_destroy

(

ThreadProgress *

pro

)

Destroy a ThreadProgress.

Can be called on a ThreadProgress that has never been initialized provided that the ThreadProgress struct has been initially zeroed. Must be called even if ff_thread_progress_init() failed.

ff_thread_progress_report()

void ff_thread_progress_report	(	ThreadProgress *	pro,
		int	progress )

This function is a no-op in no-op mode; otherwise it notifies other threads that a certain level of progress has been reached.

Later calls with lower values of progress have no effect.

ff_thread_progress_await()

void ff_thread_progress_await	(	const ThreadProgress *	pro_c,
		int	n )

This function is a no-op in no-op mode; otherwise it waits until other threads have reached a certain level of progress: This function will return after another thread has called ff_thread_progress_report() with the same or higher value for progress.
