Hi, you can send key events, but it is very platform specific. There might be a xplatform python package out there somewhere to send key events... but I'm not sure. Maybe it wouldn't be too hard to make a win/mac/X module yourself if one doesn't exist.
Perhaps mplayer with slave mode would be a good one to start with? Here is the page which describes it's slave mode: http://web.njit.edu/all_topics/Prog_Lang_Docs/html/mplayer/#slave I'm sure you've noticed, but using communicate with subprocess can prevent hanging - compared to using stdin/stdout directly. cu, On Fri, Jun 19, 2009 at 3:44 AM, Tyler Laing<trinio...@gmail.com> wrote: > Well, the movie module will use different back ends.
