Hi everybody,

There is a three seconds delay when i stream MPEG2 with VLC. The work conditions are:

Hauppauge 250
VLC 0.7.2
Pentium IV
Red Hat 9
The instruction is:

/usr/local/bin/vlc -vvv pvr:/dev/video0:norm=pal:size=720x576:frequency=576250:bitrate=3000000:maxbitrate=4000000 --sout udp:239.10.10.239:1239 --ttl 12 --cr-average 1000

How can i reduce the 3 seconds delay to, at least, one second?

Can anybody help me?

Thanks,

vlc --longlhelp --advanced | grep cache
vlc --longlhelp --advanced | grep buffer

play with that. both client and server side

you´re suggesting to read the longhelp from vlc, but there´s nothing about cache.

Talk about buffer, but just for ffmpeg, not for streaming live video with hauppauge 250

What do you think?

The actual term to seek is "caching". If you're hardware encoding, on the card itself, you can knock down the VLC UDP caches, but I don't know if you can access the on-card buffer used to do the encoding.

How can i knock down the vlc UDP caches??????


The VLC streaming server is Redhat Linux, and i use the command line, no windows.....


Thanks a lot big boss!!!!!!!!!!!!!!!!!!!!!1
