Hi, Do you have any progress in forming a Linux+Video+OpenGL working group? Currently I am looking for a colorspace conversion solution implemented using OpenGL. It is not hard to find one, but most solutions use high-end video card extensions and do not provide any software fallback. I think we must build reusable software to do low level tasks such as image composition, video mixsing and colorspace conversion which are repeated over and over again in constructing various video applications.

My Background: I am hacking the "Open Movie Editor", it does simple OpenGL based compositing, but it does not use gstreamer. What I am interested in: Hardware independence: Currently working with OpenGL and Video is a mess, every Driver and Hardware has different Features and Capabilities. There is powerful hardware available that should be exploited. There is Mesa that has a software implementation as fallback, but there are still gaps and circumstances under which certain OpenGL extensions are simply not available. Somehow this needs to be worked around. Reusability: Do the [ground/grunt]-work once, and enable a wide range of applications/frameworks to reuse that work. I hope this would be in the interest of all involved parties?
