hello,
i don't know what changed, but i am now able to use RECT texturing with shader under linux. i don't have time yet to test if my patch will get a performance boost like this, but i hope i'll be able to use multiple texturing now.
that will make my life easier.

with RECT texturing mode and pix_movie, thing are lot's faster. multiphreading works better to. I can use about 25 DV clip at 25fps, using about 250% cpu. everything work now as expected....
ok, macpro are not so bad after all :-)
25 is a more than I have gotten running so far - maybe PAL is more efficent than NTSC. The reason pix_movie is so much faster is that it uses the most efficient texturing path by default. The standard pix_texture code waits for the texture upload to the GPU before continuing which stalls all of the rendering. You can send a 'client_storage 1' message to pix_texture to try and get that object to use the more efficient code but it doesn't always work - especially on the MacPro with ATI.
