Emptying the buffer of a receiver of a live stream

Hi,

In my application, a publisher starts a live video and a receiver could recieve it through FMS rtmp. The problem:

1) Once the receiver faces latency, due to slow connection, the latency keeps on increasing from 1 second to 10s, 20s and above. What i feel here is that the reciever's buffer starts accumulating video data and keeps on accumulating it and never flushes it.I am unable to find a property in netStream and Application.xml to empty the buffer of a poor connection reciever.

How can i fix this issue, so that a slow connection receiver's latency remains constant around 2 - 3 seconds. Please help.

Regards,

Sahil.
