  Hi 
	We have designed a IP steraming box using PowerPC processor of 350 MIPS speed along with 64 MB ram & 10 mbps ethernet.
I ported vlc 0.7.0 to that box and tried UDP/RTP streaming.

I use vlc for windows as my streaming server in xeon processor.

Observations
------------
1)when we transmitt with a MPEG2 stream in 512kbps bitrate from server and try to stream with IP box there is negligible packet loss
and no flickering in video.
2)when we try with 1 mbps & 1.5 mbps bitrate there is some packet less & very less flickering.
3)when i with more than 1.5 mbps there is heavy packet loss & more flickering in video.
4)when we try in Linux PC as streaming client in same network it works fine,but our box gives above problem.
5)Even we tried directly connecting the IPbox to the server using cross cable,the problem persists.


My doubts
---------
1)Does vlc requires more memory & processing power for handling higher bitrate streams.
2)whether 10 mbps ethernet is not sufficient to stream more than 2 mbps bitrate stream.
3)buffering is not for vlc for reading the ethernet socket.(As i saw in vlc/modules/misc/network/ipv4.c that 0.5 mb buffer is needed to avoid packet loss but linux allocates less than that)


Awaiting for your suggestions to resolve the problem.

With Thanks & regards,
