You also need --vout image to enable image output module.

This doesn't appear to work anymore. Could someone please help?

I would like images, any images from a file. I'm sitting at the command line and everything I type either "The command line options couldn't be loaded, check that they are valid." or I'm watching at my video play and no screenshots are saved. Seriously this should be child's play. What is going on?!

Vout image isn't anymore. It is scene video filter now
