No

I manually insert feparams into the sqlite database and all I get when I scan the mux is this:
[34715.454224] DVB: adapter 1 frontend 0 frequency 12647000 out of range (950000..2150000)
I am also not able to turn off manually lnb voltage or enable/disable lnb sharing.

    Manually adding items to the database is not supported nor will be in the future.
    Either use an existing channels.conf file and the app setupdvbstreamer or use the dvbstreamer command:scan network "NETWORK SCANNING DATA"
    Where "NETWORK SCANNING DATA" is a single line from the network file you would have passed to the standard dvbutils scan app to generate a channels.conf file. With the scan command you need to wait a while for it to scan through the network. Use "getprop commands.scan.inprogress" to determine if the scan is still going.

    Use setprop adapter.lnb.sharing True to enable LNB sharing. I think this is only available from svn at the moment though and hasn't yet been released.

    Hello,
    Many many thanks for the quick answer but I've already tried scanning manually with the scan network command. I've waited even 5 minutes and didn't get any scan info...
    Here is what I get with your commands:
    DVBStreamer>scan network "S 12525000 H 30000000 3/4"
    DVBStreamer>getprop commands.scan.inprogress
    False
    DVBStreamer>
    Can you do an example scan network for DVB-S? I only see for DVB-T
    Thanks.
    LNB Sharing works fine. I'm using latest svn version.

    Doh, Its a bug in the help for the scan command!

    It should be:
    scan net "S 12525000 H 30000000 3/4"

    I'll try and get that fixed.

    Hello,
    scan net command IS working but scan network is not.
    Weird...but now I have what I need and once again many thanks.
    P.S. You should fix the help scan command to respond scan net instead of scan network.
    Thanks

    Hi,
    How do a I scan S2 transponder?
    //
    DVBStreamer>scan net "S 11012000 V 30000000 3/4 35 8PSK"
    DVBStreamer>feparams
    Delivery System: DVB-S
    Frequency: 11012000
    Inversion: AUTO
    FEC: 3/4
    Symbol Rate: 30000000
    Polarisation: Vertical
    Satellite Number: 0
    //
    It says DVB-S not S2...but the transponder is dvb-s2.
    Thanks

    Ok,
    I've found out how to see all the props but I have received a lot of sefaults while trying to modify some of the values. For example:
    setprop adapter.systems (whatever I put I receive this)
    setprop adapter.number also segfault...
    LNB sharing works but I can't change the delivery system for scanning... I'm trying to scan DVB-S2 transponder which seems to be impossible without setting up channels file first.

    Here are segfault errors:
    [39805.697207] dvbstreamer[23542]: segfault at 0 ip (null) sp 00007f7e8575cd78 error 14 in dvbstreamer[400000+46000]

    Thank you in advance

    Thanks for the report on the segfault. It should now be fixed in svn.

    The properties you are trying to set are readonly.

    You don't need to specify a delivery system when you scan a frequency both DVB-S and DVB-S2 are tried automatically. If the transponder you mention below locks and works don't worry about it.

    Hi,
    I've found that the default adapter.lnb is User Defined when database is created.
    Is there any possibility UNIVERSAL to be setup as default adapter.lnb because it's the most common used.
    Thanks

    Hello,
    DVB-S2 scanning is not working yet.
    I've tried scan net "S 11012000 V 30000000 3/4 8PSK 35"
    and without 8PSK 35 and nothing...still tuned on DVB-S.
    Is there any way to switch to DVB-S2?
    Thanks
