What is happening...I am experiencing a kernel panic when runing mumudvb and connecting to both tuners at the same time. Both tuners work if I run them independently one by one, but not both together.

Suggestions?


Thanks,

Hi mitja

What about other application such as dvblast ?
Is it the same ?

Thanks

Kind Regards

Hi mitja ,

could you send me the configure of mumudvb ?

Best regards !

[mitja]

Here it goes:

# cat udp_mux1.cfg
================================
card=0
freq=522000
srate=27500
autoconfiguration=full
autoconf_ip4=239.100.%card.%number
autoconf_sid_list=1 2 3 5 6 7
================================


# cat udp_mux2.cfg
================================
card=1
freq=570000
srate=27500
autoconfiguration=full
autoconf_ip4=239.100.%card.%number
autoconf_sid_list=20 21 22 23 24 25
================================

Hi steven,

I just installed dvblast and it looks that I am doing something wrong...

Any ideas why it reports unable to query frontend?

Any ideas why it reports unable to query frontend?

Mumudvb running at the same time?

Hi,

I have simmilar problems with my TBS5280, but I use tvheadend. Everything is fine when I'm using one tuner. When I'm using both tuners -after few times everything is hanging up with a lot of "UsbInterface::sendCommand, failed with status --19" and other stuff (like xhci errors)... When I disable one tuner everything work fine...

Does anybody knows how to fix that?
