dvb device with multible frontends

[geos_one]

it looks like that the device scan can only find the frontend0 

Code:

root@media:~# /opt/nextpvr/system/DeviceHost/x64/DeviceHostLinux -discover
<devices>
  <device>
    <name>adapter0 (Realtek RTL2832 (DVB-T))</name>
    <type>DVB-T</type>
    <filter>adapter0</filter>
    <instance>1</instance>
    <resource>adapter0</resource>
  </device>
  <device>
    <name>adapter0 (Realtek RTL2832 (DVB-T))</name>
    <type>DVB-C</type>
    <filter>adapter0</filter>
    <instance>1</instance>
    <resource>adapter0</resource>
  </device>
</devices>

but with dvbv5-scan yo can specify the fronentd to use

Code:

Check

ls -lt /dev/dvb/adapter0

You might need to add nextpvr to the plugdev group

sudo usermod -a -G plugdev nextpvr

Code:

root@media:~# ls -lt /dev/dvb/adapter0
insgesamt 0
crw-rw---- 1 root video 212, 4 Aug 21 21:18 frontend1
crw-rw---- 1 root video 212, 3 Aug 21 21:18 frontend0
crw-rw---- 1 root video 212, 2 Aug 21 21:18 net0
crw-rw---- 1 root video 212, 1 Aug 21 21:18 dvr0
crw-rw---- 1 root video 212, 0 Aug 21 21:18 demux0

usermod -a -G video nextpvr

no differnce still only the frontend0 so only dvb-c dvb-t but not dvb-t2

[mvallevand]

The installer already adds nextpvr to video. Sub will need to comment on how inje detects the instances.

also added it to plugdev and reboot the server still the same.
ne frontend1 detect

I can't remember if I've explicitly tested this. I'll have to see if any of my DVB sticks give 2 front ends.

[sub]

Unfortunately none of my tuners use drivers that make multiple frontend.

Exactly what name/model is your device? I'll see if they're available here, and what price.

[geos_one]

it is this stick from china.

with an additional better antenna

its an Astrometa DVB-T2 usb stick
at the price of 2 starbuck's coffes

Maybe this will help swap frontend0 and 1

I've ordered one. It's likely it'll take a few weeks to get to me though. In the meantime, you might as well try Martin's suggestion above.
