octave video/avi crashes - anybody have similar experience?

[Kenneth Johnson]

 

I have 3D arrays of processed images (x,y,t) i'm trying to dump to an avi file.  x=y=t = 128.

 

The data is we;; behaved in that it is between 0 and 1.

 

I created a simple function to do it as listed below - sometimes it works and about 50% of the time it causes a core dump when the function returns back to the caller.

 

Anybody have an ideas - i've tried all kinds ot tricks to "clear" whatever error might exist behind the scenes in the lower level code like writing a zero frame before and after, etc.  But it is still very unreliable and I'd really like to get it fixed because I want to use this capability ALOT...

% convert3DtoAVI(File, Array)

 

function [] = convert3DtoAVI(RootName, SubName, Wavefront)

 

% -- Open file and stuff frames

 

OurPath = "c:\\Users\\Owner\\Documents\\Octave\\";
AVIName = strcat(RootName, SubName);
filename = strcat(OurPath, AVIName);

printf("convert3DtoAVI: %s\n", filename);

 

% --

 

[xSize, ySize, nImages] = size(Wavefront);

Image = Wavefront(:,:,1);
ZeroImage = zeros(size(Image));

 

% -- This is the avi loop

avi = avifile(filename);

 

% --

 

addframe(avi, ZeroImage);

 

for i = 1:nImages

 Image = Wavefront(:,:,i);
 sImage = ScaleImage01(Image);
 addframe(avi, sImage);
 
end

addframe(avi, ZeroImage);

%aviinfo(filename)

endfunction
