Hi,

 

I'm trying to get tvheadend as a Sat>IP Server for my Vu+Ultima 4k to run, so I can get DVB-T2 channels. The vtuner seems to be detected fine and is listed under the tuners. However searching for channels gets me no channels. Tvheadend seems to temporarily add a multiplex which it cannot tune to.

 

I've done some network capturing. (see attached PCAP file) Enigma seems to request the following stream:

SETUP rtsp://192.168.5.5:554/?freq=626&bw=8&msys=dvbt&pids=none RTSP/1.0

CSeq: 1

Transport: RTP/AVP;unicast;client_port=45080-45081

 

RTSP/1.0 200 OK

CSeq: 1

Session: 0954A434;timeout=30

Transport: RTP/AVP;unicast;client_port=45080-45081

com.ses.streamID: 18

 

I suspect that the msys=dvbt parameter is wrong, as this is a DVB-T2 multiplex. Unfortunately there seems to be no way in the GUI I can set this for DVB-T.
 

Is there any way I can further debug this? I'm sorry that I can only provide such a short and incomplete report.

Thank you very much. The github repo didn't work for me directly, I had to patch it so it would always output dvb-t2. This is strictly speaking wrong, but since everything is dvb-t2 here it works.

This is strictly speaking wrong

What do I need to fix in satip-client so that the dvb-t2 definition works correctly?

 

 

And one more question, how do you watch encrypted channels?
