As the title says, does anyone know of anything than can generate a contact sheet (e.g. jpg etc) from a video? I’m mainly interested in starting from FLV files, but i guess the solution will probably work for other formats with appropriate codecs etc. So, for example, if i have a 30 minute video, every 2 minutes i’d like it to generate a thumbnail and then put 15 of these in a 5 x 3 grid in a single jpg. On Windows, “Media Player Classic Homecinema” will do this through its “Save Thumbnails” command.
Ideally i’d like to do this from the command line/script in a debian server environment, rather than a desktop GUI. It doesn’t have to be a single command, if a chain of steps could do it.
Thanks in advance.

The package ‘ffmpegthumbnailer’ from the Debian package repositories should do what you need.
Example: (assuming RickRoll_D.flv and wanting to produce 11 thumbnails from 0% to 100%)
$ for ((i=0; i<=100; i+=10)); do ffmpegthumbnailer -i RickRoll-D.flv -o thumb${i}.jpg -t \${i}; done
The FFmpeg utility can generate thumbnails by itself as well – Prashanth Ellina’s blog entry gives examples.
