DVB-T streaming issues with 0.7.2

[drouetn]

Hi,

I'm trying to stream from my Nova-T PCI card on a SuSE 9,1 system using 0.7.2. I've been following the Streaming howto on the VideoLAN web site but I think that something is out of date there and I'd be interested if others have this working.

I'm issuing the following command to start the stream:

vlc -vvv --program 248 --dvb-adapter 0 --dvb-frequency 50583300 --dvb-srate 2750000 --sout udp:192.168.1.195

and the following appears:

From what I can make out here, the DVB card isn't being used at all - I can shutdown my card and unload the modules and get the same error. Following the docs in the howto gave me errors about deprecated dvb syntax.

I've managed to use dvbstream to capture a feed from my card and I can display the file via VLC on a Windows PC and an Amino 110 STB with no issues, so I don't suspect anything wrong with my card or drivers.

Can anyone offer any assistance in getting VLC streaming with DVB? I'm in London receiving from the Crystal Palace transmitter if that matters...

Thanks

Nick

you only specified options, you didn't specify WHAT you want to open with VLC.

for starters add something like dvb:
This will add a DVB playlistitem.

Hi,

OK I forgot to put the dvb: bit in there. Forgive my stupidity...

I've amended the syntax and now my card is indeed probed but the FEC seems to not be read from the command line -

the line I use to start up VLC is

linux:~/vlc-0.7.2 # vlc -vvv dvb:adapter=0:frequency=50583333:program=258:fec=9:s-rate=2750000

From my understanding FEC can be 9 or auto, but I've tried all of the possible ones and the output is the same...

The output is as below:

I'd be grateful for assistance to crack this - the docs don't seem to cover this topic in too much depth.

i don't know much about this topic. Did you try searching the mailinglist archives? I'm sure i've seen similar problems on the lists...
