Qam

Any chance you could capture a one minute full stream from one of the channels on that frequency, and put it somewhere like onedrive, or dropbox, and let me know the download link? I'll load it up here in my signal generator to see if I can reproduce the issue

If you're capturing it on windows, you can use the eval version of tscapture from https://tscapture.com

You can also do it in linux if you have a zap conf file

dvbv5-zap -P -t 60 CHANNEL -c name.conf -o mpeg.ts

When I try to watch any of the found channels I get an error "streaming failed (transcoder exited).

[mvallevand]

When it crashed it probably fails to create adapter0-QAM-channels.conf properly. You need to do the capture outside NextPVR using Windows or linux.

What is a zap.conf file?

[mvallevand]

You can do your own scan outside of NextPVR with https://www.linuxtv.org/wiki/index.php/Dvbv5-scan

dvbv5-scan /usr/share/dvb/atsc/us-Cable-Standard-center-frequencies-QAM256

this create a file for "zapping" probably historically like we used to zap channels with the remote. The default name from the scan is dvb_channel.conf

dvbv5-zap -P -t 60 57.00MHz#63272 -c dvb_channel.conf -o mpeg.ts

assuming the scan finds that channel too.

I ran the scan; this is the screen shot

If you run from a folder you can write too like ~ does that change? Also did you post you could scan this with TVHeadend on this PC?

[donbrew]

So far this PC is virgin Ubuntu 18.04.3 only things added are SSH and npvr 5. On the other PC with Ubuntu 19.04 TVHeadend did scan.

Tried running in ~/ same result. /opt is set to 0777.

That's weird it's even crashing with dvbv5-scan. It's sounding like either something with the driver, or something in your broadcasts that libdvb doesn't like.

Might be worth creating a copy of /usr/share/dvb/atsc/us-Cable-Standard-center-frequencies-QAM256, which has that one frequency removed, to see if dvbv5-scan can get past that frequency.
