Am trying to use dvbloopback in a setup with two cards, but it seems
to fail, I get these errors;
Nov 6 09:30:30.151 frontend: Could not open /dev/dvb/adapter2/
frontend1. Error was: 14
Open failed
: Bad address
Nov 6 09:30:30.151 demux: Could not open /dev/dvb/adapter2/demux1.
Error was: 14
Open failed
: Bad address
Looking in /var/log/messages, I see the errors;
Nov 6 09:30:30 htpc kernel: Failed to find private data during open
Looking into the dvbloopback kernel module source, it looks like it's
not able to retrieve its private member variables;
lbdev = (struct dvblb_devinfo *)dvbdev->priv;
if (lbdev == NULL) {
printk("Failed to find private data during open\n");
return -EFAULT;
}
This would indicate something serious is happening with the kernel
module loading? I am using kernel 2.6.26, am not sure if there are any
incompatibilities there, as the compile script seems to support up to
2.6.25 only?
Is the dvbloopback module author subscribed to this list?

Dvbloopback (and so sasc-ng) is kind of taboo on most MLs. Unjust, in my opinion. Sure, the software can be abused for signal "piracy" or whatever you want to call it, but in the same way can you abuse Azureus, Gift, ... for illegal downloading. In the same way is watching a dvd in America some silly patent infringment thing or what-ever. So, to anyone, I use sasc-ng (and a couple of my friends, too) so that we can use 1 smartcard for several tuners. This is in no way illegal (at least not here in Belgium). However, it could be a breach of contract, but that's not any worry of this list. (And since my provider supports settop-boxes with multiple tuners I'm not worried, too) And after ALL that, just talking about using and compiling the progrem certainly isn't illegal. I know nobody has said anything about "don't mention sasc-ng on this list" yet, I'm just preparing. Anyway! Are you using S2API and the S2API patch found on open-sasc-ng's trac? Because I have the same problem ("error 14", I don't get the "private data" bit, though) with kernel 2.6.26 (which came with Debian Lenny) AND with my own compiled 2.6.27 In my case it must be an S2API thing, because when I was using Multiproto everything worked fine. Or maybe it's a regression in the latest revision (r53?) I should find out ...

I am using a pretty recent version of the hg code yes. DVB version is set to 5. I guess I need to find a less recent version. -- Torgeir Veimo torgeir@pobox.com _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb ^ permalink raw reply [flat|nested] 5+ messages in thread

I should find > out ... dvbloopback copies a number of functions from the dvb source which aren't exported through the API of which some may have been altered, nor is it afics prepared to carry the additional tuning attributes. It is thus a fair assumption that it may need a bit of attention to fully support tuning via DVB-API v5. //per _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb ^ permalink raw reply [flat|nested] 5+ messages in thread

I guess dvbloopback would need to be updated to current DVB v5 with S2API support eventually.. -- Torgeir Veimo torgeir@pobox.com _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb ^ permalink raw reply [flat|nested] 5+ messages in thread
