Actually this is only kind of fun, so I will consider this in the future scenario ... however it would be fun to have a small simple mpeg2 player box on a beagleboard - just for learning, so I'll begin with the framebuffer ... > > maybe with gstreamer (as I worked with that before) as there are > > decoder libraries from TI avialable. > > Right, so, we have clutter-gst that provides a way to interface playbin2 > with clutter though a custom sink and a ClutterActor that you can use in > your scene. I was able to create a clutter actor with gstreamer on my desktop system, which plays smoothly (which is an Atom with Nvidia) but the mpeg decoding is done in software. What actually hurts is the deinterlacing of recorded TV streams ... as I do not get a gst vpaud decoder to run, but thats another story. > The way the upload is done right now is generic: You grab the data out > of the frame and upload it to a texture.
