You are correct Cg and BrookGPU both use the GPU as extra processing 
unit. But you should wonder a few things: is floating point what you 
want for calculations, if so what would be faster GPU/CPU and what would 
be more compatible.


It is nice to code for an Ati or nVidia chipset. But you tighten 
yourself to those implementations. It isn't strange if it only works 
with close source drivers. Other users can benefit more from MMX/SSE/etc.


I think if someone created proof-of-concept plugins using the GPU it 
would be good to compare. When I was working on BrookGPU for 
benchmarking a libm on GPU we found out that a lot of time was spend in 
actually transferring the data from and to the graphics card. The GPU is 
a great 'reduction' machine. Maybe stuff changed :)

Hi Craig,

I don't understand what you said. I thought that nvidia cg offers frame
buffer object to read data back from graphics card.

The graphics processor on the video card is not designed to send
rendered output back to the main processor. OpenGL instructions come in
one end, and rendered output goes out the other end ... to the monitor.

It's unfortunate we can't intercept this data. Solid modelers such as
Blender could probably use it, too. Maybe someday there will be enough
market demand for the hardware to change.

There are still some 3 hrs of Mar 12 left here in the USA were google is
located...

But it is good to have it in ahead of the absolute deaadline anyway.  Is
a copy of the applications available somewhere?

we probably can't...

as i stated earlier, i believe a formal organisation with formal
processes has much better chance of managing the mentoring, but then
again, it might be that google does not care about it when evaluating
the proposals.

i hope cinelerra-cv has real chance to get the students working on the
code...

 "Today" = Yesterday?

Riccardo (giskard) has already submitted the proposals with
Cinelerra-CV as the mentoring organisation.  How do we 
resolve the overlap?

Re: [CinCVS] MJPEG captures not loading correctly

[Peter Federighi]

Harm,

Thanks for the files.  The full resolution file does load correctly, but
the half resolution file does not (as you observed).  What we experience
with the half resolution file, I experience with all files recorded from
my DC30+.  It may be that it's because I'm recording in Windows.  I'll
have to try it in Linux when I get the chance (which might not be for a
while because I'm moving soon).  In any case, it confirms there is some
sort of bug.

And now for something completely different...
Do you know if the DC10+ does a better job of digitizing analog video
than the DC30+?  The reason I ask is because the videos that you uploaded
to your site are beautiful.  I've never managed to record anything that
clear with my card no matter how good the source was.  Do you know if it
had to with the fact that you recorded a PAL signal?

Anyway, thanks for confirming that there is some sort of bug in reading
MJPEG files.  I hope it gets fixed sometime.

- Peter

Many of them are commented out or only present in some special code
paths, they where added by the developers to aid debugging. Double check
them.

PS: I am slowly transisting cinelerra to use my debugging library
(http://www.pipapo.org/pipawiki/NoBug) instead of printf's in my branch.

Re: [CinCVS] error with mov file

Hello.  In trying to open a mov file, I get the following error:
virtual int FileMOV::read_frame(VFrame*):   
quicktime_read_frame/quicktime_decode_video failed, result:


I'm using cinelerra on a Debian Etch system.  It was installed with   
the following repository:

deb http://www.kiberpipa.org/~minmax/cinelerra/builds/sid/ ./

I have w32codecs installed also, from the debian-multimedia repository.


:) that should help you to transcode your mov in a format "suitable"  
for cinelerra"


did you have mencoder or ffmpeg installed?
Target is to change audio/video codec..can you tell me which are  
the original ones?


use

$ qtinfo  file.mov

 installing quicktime-utils before

;))

All help appreciated.

I read the source code and see lots of printf statement. I build cinelerra
