You can achieve that with the help of ffmpeg. Decode the video,
convert it from YUV to RGB and put the data into a texture by using a
dumy image and a texture chunk. We work a lot with video textures
here (in fact I'm currently sitting in Düsseldorf on a trade fair
with 4 interactive systems playing videos that way behind me ;) ). I
wrote a wrapper for ffmpeg on basis of some tutorials (http://
www.dranger.com/ffmpeg/ffmpeg.html) and ffplay that can be used under
LGPL (if you compile ffmpeg accordingly). It needs some cleanup, but
if it's urgent, I can send it to you as it is. It makes also some use
of SDL (EventHandling, Threading) and can't handle videos without
sound so far, but you might get an idea how to use it.

That would be cool, but unfortunately, this won't work... You have to
do it the hard way.
