I don't think there is currently an example skin for the OSMF framework. If I recall correctly, Ryan's conenct session mentioned that they are considering a skinning example for the 1.0 release.
There's no one right way to create a skin -- it all depends on your needs (and things like wether you're targeting the IDE, Flash Builder, or Flex -- or all of these). One thing to keep in mind is that because of security requirements OSMF plugins must reside in the same domain as the player swf. So you can't have a skin OSMF plugin (or any OSMF pugins) hosted separately.
There is one example from Edwins MAX presentation. I need to look deeper into these classes to figure it out.
Is that true with osmf plugins not being able to load from different domains? I have an example working which loads an akamai plugin from a different url than the player. Possibly this just works for testing.
FYI, this sprint we're adding a 'web player' sample that features its own control bar. The code is likely to still change quite a bit, but perhaps you may find it helpful already, as a sample. The sources are at:
This should help me out a lot. Thank you so much!
