Thank You very much:

Now i can compile the movietex.c program with the OpenGL, GLX extensions for
video.
BUT, it still not working !
We are working with an ONYX RE2, with a Sirius Board.
We have some programs texturing video:
in IrisGL (like vidtotex.c),
in Performer 1.2 with gl callbacks,
in Performer 2.0 with his own functions but IRISGL define.
Now we are porting to OpenGL our main software and almost all works but not the
video texturing.
We were trying to compile the movietex.c program in OpenGL, but we didn't know
about PATCH 154 or PATCH 918. Now whith this patches installed, we can compile,
but nothing happens, the movietex window outputs a white poligon rotating, but
if we compile with IRISGL define the poligon has the video texture.
Investigating throught www.sgi.com we have found the "videotex.c v1.7" program.
We have compiled it and it works OK. It uses the GLX Video extensions and
OpenGL. This is why we think that our software configuration is OK.
Then we have two questions in mind.
What is wrong in the movietex.c program ?
If the Performer has some problems texturing video in OpenGL, should we use our
own OpenGL Callbacks, like we were doing in Performer 1.2 ?
