flv streaming and proxy_pass

[Max]

Hi,

Do you use this module to stream? http://h264.code-shop.com/trac

This might not useful for you, but just for references.

I use this to stream mp4 movies (h264 video code) with lighttpd(they have a
module for ngnix and apache), it's working great and without any problem.
