[Red5] Controlling the bandwidth of published streams

[David Négrier]

Hi list!

First of all, a big thanks to all the Red5 team for their incredible 
work (and the upcoming v0.8).

I've been successfully developping some apps with Red5, and everything 
seems to work great so far.
I'm now playing with security features, and I would like to limit the 
bandwidth of an upload stream (a stream published through a webcam).

Basically, I would like my application to reject any stream that is 
published at a bitrate higher than 300kb/s.

I first thought I might do that with the 
IStreamPublishSecurity.isPublishAllowed() method.
But the codec information is not sent so this is obviously not the right 
place to do this.

Then, I thought I might use the "Bandwidth Control Framework" to limit 
the upload bandwidth.
I read this wiki page: 
http://jira.red5.org/confluence/display/streaming/Bandwidth+Control+Framework

After testing a few things, it seems that the "Bandwidth Control 
Framework" can limit the speed of downstream connections, but not the 
speed of upstream connections (there is no "setBandwidthConfigure" 
method on a IBroadcastStream). I thought I could limit the upstream for 
the whole connection instead of limiting a particular stream since the 
article refers to a IConnectionBWConfig.upstreamBandwidth but it seems 
not to exist right now.

Is there any way to limit the bandwidth for a published stream in the 
current version of Red5? (I'm using a snapshot of Red5 that is 3 months old)

Best regards,
David.
