I downloaded it, tried to compile it.. but, of all things, it stopped when checking if I had python. Just stopped.. I left it alone for an hour... nothing happened.
Tried that a few times, same error everytime.. and yes, I do have python installed, and yes, i tried to specify the path..
It would be great to have this thing! But, when you compile it, please include lame so that we can reencode streaming on the fly !
