Hi Matthew, Using those libraries directly in pyglet might be difficult due to licensing differences, but it's an interesting first step to work out using them as external modules. Going forward, it will be better for pyglet to have its own direct wrapper.
I would recommend looking over the pyglet.media.sources.Source and StreamingSource base classes, and looking at the avbin module for an example of how it can be subclassed. There are basically only a few methods needed for seeking, getting audio, and getting video packets. The hard work, of course, is working out how to fetch this data behind the scenes.
