[gst-devel] Google Summer of Code: advanced OpenGL video mixer/renderer

[Florent]

>  I would like to concentrate more on video processing, and less on mixing.

In fact, pigment's gstreamer excellent videosink already does
OpenGL-accelerated colorspace conversion, are you thinking of a more
general-purpose (and portable) plugin + library ?

On the same vein, you might be aware of the new gst-plugins-gl
repository, which contains similar, independant elements (ex:
implementing colorspace conversion in an independant manner). However,
when multiple elements are used, unless implementing some form of
context sharing, textures are uploaded back and forth between each
processing step...

Anyway, good luck :)
