Hi Folks,

I have a VuDuo2 and a HDHomeRun (this is a network DVB-C / DVB-T tuner). The two tuners built-in are not enough, so I was thinking to connect my HDHomeRun network tuner to my VuDuo2.

With some effort, I was able to cross-compile the Library from the Vendor as well as the open-source kernel module.

Once loaded the kernel module is creating the necessary devices in /dev/dvb/ (adapter1 and adapter2 below):

# ll /dev/dvb/*
/dev/dvb/adapter0:

Also the helper application that is part of the kernel module is working without any issues:

Using dvbsnoop you can see that the tuner is working fine, however Enigma did not recognize the tuner (or rather the two new tuners). After a little research I found out that Enigma is not looking at /dev/dvb/, but rather reads /proc/bus/nim_sockets to list the tuners. Unfortunatenly my tuner is not in this list:

# cat /proc/bus/nim_sockets
NIM Socket 0:
Type: DVB-C
Name: Vuplus DVB-C NIM(CXD1978)
Mode 0: DVB-C
Mode 1: DVB-T
Frontend_Device: 0
I2C_Device: 2
NIM Socket 1:
Type: DVB-C
Name: Vuplus DVB-C NIM(CXD1978)
Mode 0: DVB-C
Mode 1: DVB-T
Frontend_Device: 1
I2C_Device: 3

I was trying to trick Enigma by pointing to a different file where I manually added my tuner, but that did not really work. Although I was able to see the tuner in the config dialogue (and I could see that it was working by checking the network traffic) Enigma did not show the video.

From what I read on the Internet this might be related to the vtuners in /dev/misc/ and maybe also the entries in /sys/class/dvb/, but I don't quite understand how these things are related.

Could anybody give me a hint how I can connect my dvb-device to Enigma?

Thanks a lot

Hi

I would also like to have my HD Homerun working with my Solo2 (VTI sorry)

Have you succeed in your entreprise since december 2013 ?

regards

Any news about this? I have HDHomeRun HDHR3-4DC with 4 tuners i would like to use with Enigma2.

Hi All,

It has been a long time since this topic was updated.  Is there any chance that someone can get the code working so that we can all use HDHomeRun tuners with Enigma2.

Regards,

Ian.

As to the missing NIM tuner entries: perhaps check the open source code of a USB DVB stick, see how it is handled there, and use that to modify the helper?

hrtunerproxy plugin should allow this. IIRC, Andy Blackburn was using it.
