i have little pity problem, , but i was really looking into references 

etc,, and didn't find anything.,., i can't find attributes for 

jit.qt.mov and jit.qt.grab which should set the import or grab that it 

will grab it without sound,, i mean,, i know that i can depress volume 

etc,, but i don't need sound at all in my patch and so it seems better 

i found only snd_active for jit.qt.grab but i'm not sure if it can do

hello,,
i have little pity problem, , but i was really looking into references 
etc,, and didn't find anything.,., i can't find attributes for 
jit.qt.mov and jit.qt.grab which should set the import or grab that it 
will grab it without sound,, i mean,, i know that i can depress volume 
etc,, but i don't need sound at all in my patch and so it seems better 
just not to import it at all,, ,
i found only snd_active for jit.qt.grab but i'm not sure if it can do 
what i need exactly.,.
thanks a lot for any help.,. ;]

In jit.qt.movie, you can remove the audio track from the movie, if you 

are really concerned about playback of the audio track. You'll have to 

determine which track has audio (gettrackinfo) and then delete it 

snd_active in jit.qt.grab switches sound capture on and off.

Are you sending the video to the graphics card as UYVY data. Check 

the colorspace docs. Then generate the appropriate geomtetry() you 

need for the lens distortion, or write a simple texture displacement 

shader (see the td.*.jxs files for an example, and read the OpenGL 

The G5 quad should be able to easily process resolutions as high as 

1920x1080 as uyvy data at > 30 fps on the GPU.

the thing is only about that i think {and so the question is also,, am 

i right at all?} that if i will be able to grab only video signal, , 

then my cpu will has less work to do even if i don't use sound from 

Thanks a lot !!,. ;]

Yes,I send the video to the graphics card as UYVY data.

But my patch is very heavy, in the same time there is a delay to 20 seconds on the video real time, 4 jit.qt.movie 256/768 and 4 submatrix, 10 jit.3m, 4 audio player etc...etc...

I'll try to write a simple texture displacement shade.

But thank you

This is probably one of the biggest problems. Sounds like you'll be 

paging to/from disk, unless you have huge amounts of RAM.

Well, if you can move any of this on the GPU, it would be 

recommended. Otherwise it sounds like you might be trying to do more 

than possible in realtime on the CPU, and may have to scale back your 

resolution in exchange for an increased framerate.
