[dvblast-devel] DVB-T2 support

[peet freud]

The w_scan output is here:

In our country the DVB-T2 multiplex is on the frequency 706000 KHz.
As I have written in the first email - tvheadend can tune (on this machine
and with this card)
this multiplex and find the TV channels without problems.

BTW Tvheadend working configuration:
{
        "delsys": "DVBT2",
        "frequency": 706000000,
        "bandwidth": "8MHz",
        "constellation": "QAM/256",
        "transmission_mode": "AUTO",
        "guard_interval": "AUTO",
        "hierarchy": "AUTO",
        "fec_hi": "AUTO",
        "fec_lo": "AUTO",
        "plp_id": -1,
        "enabled": true,
        "epg": 1,
        "onid": 8395,
        "tsid": 1793,
        "scan_result": 1,
        "pmt_06_ac3": 0
}


I have used for dvblast the configuration  parameters working
for tvheadend, but dvblast is not working with them.

There are 4 TV programs available with PIDs 1000,1003,1004,1005 in the
multiplex.

I have tried this:

cat ./dvblast.cfg
239.255.1.1:1234/tsid=1793    1       1005


./dvblast -c dvblast.cfg -a 1 -f 706000000 -b 8 -m qam_256
