DVB-S: setting frontend failed (-1) Invalid argument

Postby lejeczek » 08 Sep 2008 18:11

hi dear all,
short list: 0.9.0-test3 Grishenko, kernel v4l modules compiled from today repo, kernel 2.6.27-0.297.rc5.git2.fc10.x86_64, dvb-s: tt skystar 1 ver. 1.3, and system is fedora rawhide

** vlc command:
vlc -vvv -I dummy --ttl 12 --rc-fake-tty --sout-ts-es-id-pid dvb:// --dvb-adapter 0 --dvb-frequency 1071400 --dvb-srate 22000 --dvb-voltage 18 --dvb-tone auto --programs 9220 --sout '#rtp{dst=10.0.0.100,port=3333,sdp=rtsp://10.0.0.100:1234/test.sdp},select="program=9220"}'

** channel details taken from dvbscan:
Film4:10714:h:0:22000:2346:2347:9220

**vlc errors: -

can you guys point my wrong doing? I'm novice thus assume it's rather me.
should mention that have tried a few other channels from that dvbscan output and errors as above
and before, on fedora repo's modules this same too
thank you guys, particularly developers that work on vlc
cheers

** update: it's definitely worth looking to dmesg, ( --dvb-srate 22000(these are M and should be K(+000)
now I'm a bit further but still stuck, here:

[00000356] dvb access debug: DMXSetFilter: DMX_PES_OTHER for PID 8192
[00000356] dvb access error: DMXSetFilter: failed with -1 (Invalid argument)
[00000356] dvb access error: DMXSetFilter failed

cheers

Hum, I guess that one of you settings is wrong. Could you generate a channels.conf file with dvbscan and open it in VLC to see if that works? (All the parameters should be automatically set from the channels.conf file)
