Which version of the mjpegtools do you use ? The documentation of my version says: -i num Convert a single frame to a JPEG file. The num is the frame you want extraced as a jpeg image. It does not work that way, soory. It would work that way: lavtrans -o output%04d.jpg -f i test.avi rm output???[1-9].jpg Now everything left in the directory is every 10'th frame. Another way would be with a small shell scriptcounting up, and you only output every 10th frame (with the -i option) Whith which program was the AVI file created ? I have tested the CVS version of the mjpegtools and Gimp 2.2.10 and it works. Have you tried other programms like xv ? auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard Using Tomcat but need to do more?
