problem on converting photos of different aspect ratio into a video with mencoder
I have lots of photos, they are of different aspect ratios, for example: some of them are 2048x1536, the others are 1536x2048.
Now, I want to use mencoder to generate a avi file which can contain all the photos.
However, because of the different aspect ratios of them,
mencoder mf://*.JPG -mf fps=1 -ovc lavc -o out.avi
some photos displayed in out.avi are squished.
