Is there a YouTube GData API parameter for a query that will only return entries with a minimum and/or a maximum given duration? I've found the "duration" parameter but it only accepts the values "short", "medium", and "long".
Ok, found it!
You need to integrate such query conditions into the fields parameter, which operates on a syntax similar to xpath:
http://gdata.youtube.com/feeds/api/videos?fields=entry[*videoVariable* operator *value*]
So for what I was looking for, the fields parameter value would have been:
entry[media:group/yt:duration/@seconds > *min_value* and media:group/yt:duration/@seconds < *max_value*]
