  Correct, the PLUGIN_PROXY_FOR_VIDEO code path allows a port to use a plug-in to implement the <video>/<audio> back-end.

  The idea is that an implementation of MediaPlayerPrivateInterface uses an interface exposed by a plug-in to implement (some of) the "media engine" back end to set up and control a media playback. There isn't a sample plug-in, but it should be fairly simple to figure out how it works.

  I don't know if it is currently functional, but the WinCE port takes a similar approach without defining PLUGIN_PROXY_FOR_VIDEO - see WebCore/platform/graphics/wince/MediaPlayerProxy.cpp. Note that this code has quite a number of layering violations that would need to be fixed before a patch based on it could be successfully reviewed today.
