[sorry if this turns out to be long]
In the actuator plugin main menu, I offer the possibility to tune to a transponder "on the fly", to either quickly see what's there or to trigger a transponder scan. To do that I have this piece of code that worked find under 1.4.x but stopped working under 1.5.4:
void cMainMenuActuator::Tune(bool live) { int Apids[MAXAPIDS + 1] = { 0 }; int Dpids[MAXDPIDS + 1] = { 0 }; char ALangs[MAXAPIDS+1][MAXLANGCODE2]={ "" }; char DLangs[MAXDPIDS+1][MAXLANGCODE2]={ "" }; Apids[0]=menuvalue[MI_APID]; SChannel->SetPids(menuvalue[MI_VPID],0,Apids,ALangs,Dpids,DLangs,0);
SChannel->cChannel::SetSatTransponderData(curSource->Code(),menuvalue[MI_FREQUENCY],Pol,menuvalue[MI_SYMBOLRATE],FEC_AUTO); cDevice *myDevice=cDevice::GetDevice(DvbKarte); if (myDevice==cDevice::ActualDevice()) HasSwitched=true; if (HasSwitched && live) { if (cDevice::GetDevice(SChannel,0,true)==myDevice) { cDevice::PrimaryDevice()->SwitchChannel(SChannel, HasSwitched); return; } } myDevice->SwitchChannel(SChannel, HasSwitched); }
I.e., it creates a dummy channel with the transponder data currently on screen and tries to tune it with the card connected to the motor, cDevice::GetDevice(DvbKarte). Since I don't have a full-featured card, it's not the primary card, so the line that's executed is the last one. Putting some printf here and there, it seems that's ultimately calling cDevice::SetChannelDevice instead of cDvbDevice::SetChannelDevice, and I don't understand why, since DvbKarte is 0 (the first and only card, which should be a cDvbDevice).
What should I do to adapt to the new vdr? (BTW, I noticed that also the LoadEpg plugin stopped working, for a similar, but not exactly the same, reason: it switches for a split second to the channel with the epg data, then goes back to the previous one, so it doesn't get any data).
I suppose that I could just use cDevice::PrimaryDevice()->SwitchChannel[*], but then I couldn't be sure that the transponder will be definitely tuned by the desired card (it would be in my case, but it wouldn't when there's more than a dvb-s card).
[*]actually, I tried, but then my pat and sdt filters didn't work, but that's a different matter ;-)
