Hi there, looks like mencoder does not work correctly with grayscale images using a command like this: mencoder \*.jpg -mf on:fps=25 -o output.avi -ovc lavc Depending on the Input format two differtent things may happen: * When jpeg is used it produces a segementation fault * When png is used it produces a somewhat crippled image which has just one third of the width it should have. Looks like 3 (RGB) channels are assumed here, but just one (grayscale) Channel is available. mencoder works just fine when the images are converted to colored images.
