hello Klaus,
I tried the patch below with a knc1 dvb-c, tt c1500 and tt connect ct-3650 I used a alphacrypt light and I also tried the classic module
always the same behavior - if I zap from encrypted channel to encrypted channel in some situations vdr says "channel not available" if I reset the cam manually it works again immediately I also tried vdr 1.4 with my old tt ff c2300 and I had no problems
maybe its a general vdr 1.7.x cam handling problem
any idea - what I can do or test to identify where the problem is?
thanks
marco

This looks more like a driver bug to me.
Well maybe but unfortunately responds to my mails in linux-dvb / linux-media mailinglist for that problem.
@Klaus: If that problem happens, a manual reset of the cam under vdr's menu->settings->ci brings the cam back.
What about trying to reset a cam automatically when it's Status is != msReady?
Like this: diff --git a/device.c b/device.c index 681049b..7904de2 100644 --- a/device.c +++ b/device.c @@ -239,6 +239,8 @@ cDevice *cDevice::GetDevice(const cChannel *Channel, int Priority, bool LiveView if (Channel->Ca() >= CA_ENCRYPTED_MIN) { for (cCamSlot *CamSlot = CamSlots.First(); CamSlot; CamSlot = CamSlots.Next(CamSlot)) { SlotPriority[CamSlot->Index()] = MAXPRIORITY + 1; // assumes it can't be used
if (CamSlot->ModuleStatus() == msPresent)CamSlot->Reset(); if (CamSlot->ModuleStatus() == msReady) { if (CamSlot->ProvidesCa(Channel->Caids())) { if(!ChannelCamRelations.CamChecked(Channel->GetChannelID(), CamSlot->SlotNumber())) {
Have you tested this? Did it actually work?
Klaus
Will give it a try and report back....
