Tuner plugin - cross link

[mvallevand]

Sub, would it be possible to add a method for a tuner plugin to somehow identify that it is linked with a native tuner? I'd like to be able to avoid scheduling a copy freely show on one tuner and a wtv recording on another.

There is already a mechanism for this. It comes down to the string you return from GetResourceIdentifier(). If two capture sources return the same resource identifier, then they're assumed to be the same device and mutually exclusive.

Ok, from screen shots you are using something like "Hauppauge DCR 2650 ID#1-0" and "Hauppauge DCR 2650 ID#2-0" It seems I just need to give the user the option to return "Hauppauge DCR 2650 ID#1-1" and "Hauppauge DCR 2650 ID#2-2" to link them. Correct?

That's description, but the resource identifier is similiar and derived from the name in the case of the DCR-2650 recorder. "RESOURCE:" + Description + ":" + 0

I'm still a bit confused from the match logic, do you match up to the second colon? That also seems different from what goes into the name field in the capture_source table for my mutually exclusive QAM/ATSC tuners. Is there something else that populates the name field?

It matches the entire strings. Note the trailing ":0" is not super significant, but is part of the string for the DCR-2650 plugin so needs to be there for a match. This trailing for ":0" was only really the because of cut&paste. The "Description" part contains the device identifier and tuner number, which is what was really needed for these DCR-2650s.

That also seems different from what goes into the name field in the capture_source table for my mutually exclusive QAM/ATSC tuners.

For analog and digital devices, its a pretty similar format, "RESOUCE:" + deviceFilter + ":" + deviceInstance. Sometimes deviceFilter is tweaked though based on data from DeviceRules.xml (which helps me match up analog and digital tuners). This is all considered internal to the capture plugins though, so wasnt really for other people to depend on, and I can and have changed this stuff between builds.

Ok thanks I was making some bad assumptions, I think I have enough to go on know.

You just had to ask this didn't you? I was blissfully ignorant until now.

Now I have to rethink some things.

[mvallevand]

Ok I can get the device names I might want to map to,

List <IRecorder> ir = NShared.HDPVRRecorder.GetPresentDevices();
// using count
Debug.WriteLine(ir[0].GetResourceIdentifier());

List<IRecorder> ir = NShared.HDHomeRunRecorder.GetPresentDevices();
// using count
Debug.WriteLine(ir[0].GetResourceIdentifier());

etc.

But my database entry and yours will look quite different. Will they still match?

24 Hauppauge HD-PVR NShared.HDPVRRecorder
27 RESOURCE:Hauppauge HD PVR Crossbar:1 NetworkRecorder.NetworkRecorder

The resource name isnt in the database. Its dynamically constructed when the app askes for it, in the format: "RESOURCE:" + crossbarFilter + ":" + deviceInstance
