Detailed Description

This class serves as the base class for all video output methods.

The basic use is:

VideoOutputType type = kVideoOutput_Default;
vo = VideoOutput::InitVideoOut(type);
vo->Init(width, height, aspect ...);
// Then create two threads.
// In the decoding thread
while (decoding)
{
    if (vo->WaitForAvailable(1000)
    {
        frame = vo->GetNextFreeFrame(); // remove frame from "available"
        av_lib_process(frame);   // do something to fill it.
        // call DrawSlice()      // if you need piecemeal processing
                                 // by VideoOutput use DrawSlice
        vo->ReleaseFrame(frame); // enqueues frame in "used" queue
    }
}
// In the displaying thread
while (playing)
{
    if (vo->EnoughPrebufferedFrames())
    {
        // Sets "Last Shown Frame" to head of "used" queue
        vo->StartDisplayingFrame();
        // Get pointer to "Last Shown Frame"
        frame = vo->GetLastShownFrame();
        // add OSD, do any filtering, etc.
        vo->ProcessFrame(frame, osd, filters, pict-in-pict);
        // tells show what frame to be show, do other last minute stuff
        vo->PrepareFrame(frame, scan);
        // here you wait until it's time to show the frame
        // Show blits the last prepared frame to the screen
        // as quickly as possible.
        vo->Show(scan);
        // remove frame from the head of "used",
        // vo must get it into "available" eventually.
        vo->DoneDisplayingFrame();
    }
}
delete vo;

Note: Show() may be called multiple times between PrepareFrame() and DoneDisplayingFrame(). But if a frame is ever removed from available via GetNextFreeFrame(), you must either call DoneDisplayFrame() or call DiscardFrame(VideoFrame*) on it.

Note: ProcessFrame() may be called multiple times on a frame, to update an OSD for example.

The VideoBuffers class handles the buffer tracking, see it for more details on the states a buffer can take before it becomes available for reuse.
