After running the following code which is trying to generate a new video based on a given video, i lost the original audio in the output video and i want to add this audio to the output, is there any solution for this that i can add it to my code, in other words i want for each frame of the video i want to add the coresponding audio sample.
The code (Just the useful part of the code):
while i1 < v1.NumberOfFrames && i2 < v2.NumberOfFrames && i3< v3.NumberOfFrames && i4 < v4.NumberOfFrames
if i1 < v1.NumberOfFrames
i1 = i1+1;
im = v1.read(i1);
im = imresize(im, [290 290]);
im = imrotate(im,-90);
iim1 = image(im,'XData',[0 0],'YData',[height1/2 - 290/2 height1/2 - 290/2]);
end
if i2 < v2.NumberOfFrames
i2 = i2+1;
im = v2.read(i2);
im = imresize(im, [290 290]);
im = imrotate(im,180);
iim2 = image(im,'XData',[width1/2-290/2 width1/2-290/2],'YData',[0 0]);
end
if i3 < v3.NumberOfFrames
i3 = i3+1;
im = v3.read(i1);
im = imresize(im, [290 290]);
im = imrotate(im,90);
iim3 = image(im,'XData',[width1-290 width1-290],'YData',[height1/2 - 290/2 height1/2 - 290/2]);
end
if i4 < v4.NumberOfFrames
i4 = i4+1;
im = v4.read(i4);
im = imresize(im, [290 290]);
iim4 = image(im,'XData',[width1/2-290/2 width1/2-290/2],'YData',[height1 - 290 height1 - 290]);
end
%frame=im2frame(gcf);
frame=getframe(gcf);
writeVideo(writerObj,frame);
