that's what i have done in 3hours of coding last night.

i took a look at youtube-viewer_0.1-1_all.deb code.

it's pretty nicely written, it uses gstreamer and has a more complex approach, you can give it a try (check the link provided above by jussik)

i'm still stubborned enough to see i can i do with my app and i will still give it a try a few more days
