Is there any way a plug-in can be delegated to for playback? Ideally I would like to see VLC handling the content, so that I could specify any URL and video format that it supports.

For example, Apple's ports use QuickTime as the media engine, the GTK port uses GStreamer, etc. It is possible for a port to support more than one media engine, but it has to be done at compile time - it isn't possible to plug in a completely new media engine at runtime.

I am looking at the possibility of using Webkit as a basis for a HTPC type application (the UI would be done HTML with JS). For this reason I would be looking at something that could easily support local file formats as well as streaming formats such as RTSP and unicast/multicast video sources. Since the target platform is MacOS X, if Quicktime already provides access to all that through WebKit, then it should be a simpler task.
