3 seconds delay streaming MPEG2 with VLC 0.7.2

Postby Guest » 22 Dec 2004 13:41

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,

The DJ

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.

--sout-udp-caching=value_in_milliseconds transmit (server)
--udp-caching= receive (client)
