Sounds like a good technical solution would be to add a cross-platform standard way to customize Pyglet's library loading preferences. It'd certainly simplify testing Libav (I currently install it and then use it via Pyglet to test it).
FYI, AVbin is licensed under the LGPL 2.1 (since Libav upstream is), so you should be aware of legal stuff if you're doing any distributing. http://libav.org/legal.html ~ Nathan On Sat, Sep 28, 2013 at 4:56 AM, "Juan J.
