// Integration tests for Pipeline. Real demuxers, real decoders, and
// base renderer implementations are used to verify pipeline functionality. The
// renderers used in these tests rely heavily on the AudioRendererBase &
// VideoRendererImpl implementations which contain a majority of the code used
// in the real AudioRendererImpl & PaintCanvasVideoRenderer implementations used
// in the browser. The renderers in this test don't actually write data to a
// display or audio device. Both of these devices are simulated since they have
// little effect on verifying pipeline behavior and allow tests to run faster
// than real-time.
