Member Function Documentation

◆ GetStats()

bool CRenderManager::GetStats	(	int &	lateframes,
		double &	pts,
		int &	queued,
		int &	discard
	)

Can be called by player for lateness detection.

This is done best by looking at the end of the queue.

◆ SetSubtitleVerticalPosition()

void CRenderManager::SetSubtitleVerticalPosition	(	const int	value,
		bool	save
	)

Set the subtitle vertical position, it depends on current screen resolution.

Parameters

value	The subtitle position in pixels
save	If true, the value will be saved to resolution info

◆ WaitForBuffer()

int CRenderManager::WaitForBuffer	(	volatile std::atomic_bool &	bStop,
		std::chrono::milliseconds	timeout = `std::chrono::milliseconds(100)`
	)

If player uses buffering it has to wait for a buffer before it calls AddVideoPicture and AddOverlay.

It waits for max 50 ms before it returns -1 in case no buffer is available. Player may call this in a loop and decides by itself when it wants to drop a frame.
