[Red5] HD Live Streaming Low Frame Rate Problem

[Giovanni]

Totally agree with Andy,

Whats your configuration for the encoder?

Live encoding is tricky if not ALMOST impossible at 1080p. Wow, you  
may need a hardware encoder to handle something that tricky but its  
not for the faint at heart.

Lowering the bandwidth will help if the initial computer is small. But  
you have also to account for users with your server.

I dont know of anyone who is broadcasting 1080p now. 720p yes, many,  
but 1080p, live?


Kind regards,

Giovanni
