Try:

 gst-launch-0.10 uridecodebin uri=file:///path/to/videofile0.mp4 !
ffmpegcolorspace ! jpegenc ! multifilesink location=image-%05d.jpg

or

 gst-launch-1.0 uridecodebin uri=file:///path/to/videofile0.mp4 !
videoconvert ! jpegenc ! multifilesink location=image-%05d.jpg

(You wanted the jpg images separately, right?)
