use boster in rygel

["Cédric Briner" <briner infomaniak ch>]

Hello,

I did not find if rygel can show poster for a video instead of a thumbnail. If so could you point me to some 
documentation or tell me how I should do it. Should I some way organize the video one per directory with a 
jpg or png with a special name.

And could we do the same for any directory.

If so, my kids will appreciate as they still have difficulties to read.

Thanks in advance.
