[osflash] buffer progressbar

[marcio at forbrazil.com.br]

Hi all, i have a question about buffer and progressbar using AS3+rtmp.

I tried much times use netstream.bufferLength but i no found a logic 
correct... i searched examples and nothing, exist examples using FLV it 
returning bytesLoaded / bytesTotal * 100...RTMP only return  bufferLength.

Anyone can help me to do buffer progressbar?

Thanks advance
Marcio
