Hi Per,
Using more than 8 DVB devices:
------------------------------
I usually, Download V4L from
http://mercurial.intuxication.org/hg/s2-liplianin,
Run an initial make (this creates the v4l/.myconfig file)
CONFIG_DVB_MAX_ADAPTERS = 8
to
CONFIG_DVB_MAX_ADAPTERS = 12 in the private config file
re-run make && make install
Using more than 5 tuners/recordings per device in MythTV.
---------------------------------------------------------
It does seem strange that MythTV limits tuners per device when some
MUXes can have up to
20 channels on them?, anyway to change this,
Update "Max recordings value from 5 to 20"
mythtv-0.xx/mythtv/libs/libmythtv/videosource.cpp
class InstanceCount : public TransSpinBoxSetting
{
public:
InstanceCount(const CaptureCard &parent) : TransSpinBoxSetting(1,
5, 1) <-----Change 5 to 20
{
setLabel(QObject::tr("Max recordings"));
setHelpText(
QObject::tr(
"Maximum number of simultaneous recordings this device "
"should make. Some digital transmitters transmit multiple "
"programs on a multiplex, if this is set to a value
greater "
"than one MythTV can sometimes take advantage of this."));
uint cnt = parent.GetInstanceCount();
cnt = (!cnt) ? kDefaultMultirecCount : ((cnt < 1) ? 1 : cnt);
setValue(cnt);
};
};
In my case my front-end has 24G of RAM and 10G Infiniband for storage
from the front-end to the back end so I can handle the potential of
recording 240 channels at once :).
One last note, the above settings are changed from mythtv-setup program,
when setting up the DVB device.
Albert.
