Thanks for the pointers, I've looked at ffmpeg a bit, but haven't come across
gstreamer and libxine before. I presume by libxine you mean xine-lib, as I
couldn't find a project website for libxine just from a google search.

My interest in libvlc in particular is it being a one stop shop for handling
the codecs and the streaming in and out of videos. I've began thinking about
how one would integrate it as a plugin, but don't yet have a clear plan of
My first step would probably be creating a SDL video out option that uses the
OpenSceneGraph to do OpenGL rendering, this would allow sdl to spawn an 3D
window with a video running it. After this I'll have to work out how to
subvert the process such that its the OpenSceneGraph plugin that sets up
libVLC such that it can be used in any OpenSceneGraph based application -
where the application will have already created windows and be handling its
own events - with libVLC taking a background role.
However, I'll look into the other 3rd party options right now to see how much
they might provide. It might be the case that I'll develop several plugins
which link to different 3rdParty video libraries. I would prefer to be able
to develop just one library though which could do it all, which is why I've
been considering libVLC.
I'll post more info how I get on.
I may well be developing a YUV to RGB fragment program as part of this work,
this will help offload some of the processing work on to the GPU, this may
well be useful to libVLC even if I don't go ahead and implement a libVLC
