Hello Sebastian, hello Eric,
I stumbled over the same error and found this report, so I attach
my findings to it - even when this report is alreay quite old ...
As of today it seems "dvbscan" has more than one problem:
- needed input file format seems more like
/usr/share/dvb/dvb-legacy/dvb-s/Astra-19.2E
- polarization from the input file gets not used
(Failed to set frontend)
- return value of dvbfe_get_info is checked wrong
(Unable to query frontend status)
- when we succeed above we get into function dvbscan_scan_dvb
which is empty ???
Therefore, in my opinion, the file /usr/bin/dvbscan in its current
state is useless.
When you was building from source you already used instead
of util/dvbscan/dvbscan the executable util/scan/scan.
That one from the package worked flawless for me (at least DVB-S):
$ /usr/bin/scan /usr/share/dvb/dvb-legacy/dvb-s/Astra-19.2E
scanning /usr/share/dvb/dvb-legacy/dvb-s/Astra-19.2E
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
