Re: octave video/avi crashes - anybody have similar experience?

[Tatsuro MATSUOKA]

Hello


I have slightly modified the function as,

%*************
% convert3DtoAVI(File, Array)
 
function [] = convert3DtoAVI(filename, 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);
 addframe(avi, Image);
 
end
addframe(avi, ZeroImage);
%aviinfo(filename)
endfunction
%***************


and carried out the test sometimes

Wavefront=rand(128,128,128);
filename='test.avi'
convert3DtoAVI(filename, Wavefront);

I could reproduce the crash three times. it happened not always but with a 
probability.
 I am using win XP pro sp3.

One of the octave-core dump is

4F 63 74 61 76 65 2D 31 2D 4C 00 08 00 00 00 2E Octave-1-L......
6E 61 72 67 69 6E 2E 00 00 00 00 00 FF 06 00 00 nargin..........
00 73 63 61 6C 61 72 07 00 00 00 00 00 00 08 40 .scalar........@


However, I cannot reproduce error at some moments. ????

Perhaps something is wrong but .....

Sorry I can say any further at this moments.

Regards

Tatsuro
