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.
