OpenGL texture as input

[Dušan Poizl]

Hello,

with release of gstreamer 1.4 and merging plugins-gl plugins to
plugins-bad if it is possible to use OpenGL texture as input to encoding
pipeline.

Now I have this simplified pipeline.

OpenGL RGB texture -> appsrc -> videoconvert -> x264enc -> mux -> filesink

What I want to get rid of is videocovnert element or replace it with
OpenGL accelerated one. I want to avoid unnecessary copy of texture so
it is possible to use my existing texture in gstreamer-gl?
