The VideoLAN Forums

Hi all,

I have been testing streaming output on version 0.8.4a on my WinXP on low bit rates (50->200kpbs).

I have been checking the network statistics, finding out that the effective bit rate is totally different from the one requested in the transcoding parameters.
The effective is much bigger than the requested, regardless of
- what is the requested bit rate
- what is the codec
- what is the encapsulation
- what is the selected protocol

this is a typical configuration that I use (but i tried many ones):

:no-sout-audio :sout=#transcode{vcodec=h264,vb=64,scale=1,fps=6.0}:duplicate{dst=std{access=udp,mux=ts,url=192.168.0.1:7000}}

Using the strict-rc (rate control) where possible doesn't change the problem.

I installed then version 0.8.1 and the problem is not present in this older version! the effective bit rate is really close to the selected one.

I saw a few postings on the forum about bit rate problems in the out streaming.
Can anyone confirm this problem? May this be a bug introduced in 0.8.4?

thanks
Gio
