It can work using "auto" but it's not the best solution. But as long as nobody cares to submit a patch to DVB4Linux, it's second best.

It may be the best solution as all current demodulators do ALWAYS do auto-fec no matter what value is selected. Only some real old demods (~ 10 years are unable to auto-fec on DVB-S2).
And nobody ever cared about FEC for DVB-C or DVB-T(2) as the demods always did auto-fec there.

For end-users, probably, but not from maintainers point of view.

Can someone help me submit the change upstream.

 

Seems we have agreed that is the best thing to do, might as well as do it.

Actually the FEC for DVB-T (and C where it is rarely used) is not a real mandatory value to enter to see what is transmitted...... The only added value is to see it as info how the provider configured their network,.. That was why I even doubted that is should be a requirement...


WaveFrontier 28.2E | 23.5E | 19.2E | 16E | 13E | 10/9E | 7E | 5E | 1W | 4/5W | 15W

@athoik

Regarding dvb-t2 did you check for FEC 6/7 and 8/9 also? As we have them in some places ...


I think patch handles them, if not see what it was done on patch for the other values.
Wavefield T90: 0.8W - 1.9E - 4.8E - 13E - 16E - 19.2E - 23.5E - 26E - 33E - 39E - 42E - 45E on EMP Centauri DiseqC 16/1
Unamed: 13E Quattro - 9E Quattro on IKUSI MS-0916
