◆ 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.
