Comment:

Thanks for supplying the patch; it is now in v32/master.

The patch has been updated for today's master and there have been some
issues fixed.

Testing has been done with minisatip connnected to a DVB-S2 card in the
same machine as the mythbackend and with a Telestar Digibit R1 box.

Satellite LNB selection via DiSeqC is defined in the Sat>IP protocol but
is not yet implemented.

It is possible to use the same Video Source for a /dev/dvb tuner and for a
Sat>IP tuner when they are connected to the same source.

The Sat>IP support is still a new and relatively untested feature; if
anybody finds problems when testing this please add comments to this
ticket.

Comment (by Klaas de Waal):

There is an issue with Multirec and EIT on the SatIP tuner. This can be
avoided by disabling Multirec. To do that set the "Max Recordings" to 1
and uncheck the "Schedule as Group" in the Input Connections dialog of
mythtv-setup.

Comment (by Mike Bibbings):

Klaas,

In mythtv-setup Capture Card for Sat>IP I think an "Enable/Disable EIT"
checkbox is required. I ran a quick test with 4 x DVB/S2 tuners setup in
minisatip and EIT processing was continuously running on all 4 tuners.

Whilst on the subject of eit, does "SATIP" need to be added in
https://github.com/MythTV/mythtv/blob/master/mythtv/libs/libmythtv/tv_rec.cpp

{{{
void TVRec::CloseChannel(void)
{
if (m_channel &&
((m_genOpt.m_inputType == "DVB" && m_dvbOpt.m_dvbOnDemand) ||

Klaas,


Just tried DVB-T/T2 UK Freeview and it basically worked, although the
"SETUP" messages are out of specification (minisatip does not seem to
care), a couple of examples:

Sat>IP client support

First version of Sat>IP client support.
Tested with DVB-S/S2 but not with DVB-C and DVB-T/T2.
DVB-S/S2 is tested with minisatip and TELESTAR Digibit box.
LNB selection with DiSEqC is not yet supported, only direct LNB
connections.
Channel scanning works although less reliable than with /dev/dvb tuners.
EIT does work and making recordings does work. Live TV can be an issue.

Comment (by Mike Bibbings):

Klaas,



mythconverg database schema update is required to add SatIP Recorder to
profilegroups with associated entries in recordingprofiles otherwise
mythbackend reports errors like :


{{{
Jul 17 11:20:53 2004-satip mythbackend: mythbackend[5769]: E Scheduler
tv_rec.cpp:4159 (LoadProfile) TVRec[1]: Profile 'Default' not found, and

tv_rec.cpp:4159 (LoadProfile) TVRec[1]: Profile 'Default' not found, and
unable to load fallback profile 'Default'. Results may be unpredicable

}}}

Manually adding the following to the database stopped the error messages
above.


{{{
direct to database INSERT INTO profilegroups SET name = 'SatIP Recorder',
cardtype = 'SATIP', is_default = 1;
Note the id created in this case 19
INSERT INTO recordingprofiles SET name = "Default", profilegroup = 19;
INSERT INTO recordingprofiles SET name = "Live TV", profilegroup = 19;
INSERT INTO recordingprofiles SET name = "High Quality", profilegroup =
19;
INSERT INTO recordingprofiles SET name = "Low Quality", profilegroup = 19;
}}}

see dbcheck.cpp dbver == "1339" for an example using Vbox

$SCHEMA_VERSION in mythtv/binding/perl/MythTV.pm and
mythtv/bindings/python/MythTV/static.py will also need updating to next
schema version.

Comment (by Klaas de Waal):

Mike,

Thanks for the testing and for the tips. Expect fixes in the near future.

Issues not solved yet:
- DVB-T2 tuning parameters
- Recording profiles (was this not something from the PVR150/500 days,
setting MPEG encoding parameters?)
- MPTS full TS recording; described in the Sat>IP protocol but not yet
implemented.
As yet untested:
- DVB-C with minisatip

There are also still some stability issues with the TELESTAR Digibit
satellite box.

Hi Klaas,


I am seeing a mythbackend seg fault on exit from LiveTV

Attached are gdb.txt and mythbackend log relating to the backtrace. I
suspect it has something to do with the change that added SATIP to void

Completed the DVB-T2 tuning parameter string representations.
Use "auto" for all parameters that are not known.
This is not specified in the Sat>IP specification but it does
specify that all unknown values are to be ignored in which
case the server can do what it thinks best.

Comment (by Mike Bibbings):

I am seeing on occasion mythtv-setup seg faulting whilst channel scanning
on DVB-T/T2 (UK Freeview)

Attached are gdb backtrace and mythtv-setup log.

In this case minisatip is running remote to mythtvbackend on a Raspberry
Pi3 with TVHAT tuner which has the following capabilities:
