Access ImportHDPVRChannelsForm

[mvallevand]

I am playing around with adding a tuner plugin and I have decided importing from the NShared.ImportHDPVRChannelsForm will do exactly what I want for importing and enabling channels. I can load the form with XML using the base case and I can override the OnClose event to read the check items, but I can't find anyway to use the OK or Cancel buttons. Is there any way I can inherit this form and have those buttons enabled?

Sorry, but these forms were never intended for being used this way.

What exactly are you trying to do?

[mvallevand]

I want to see how hard it is to write a plugin for tuning r5000 devices. Since they can tune 100's of channels like the HDPVR using this form I figured I could leverage all the work that you have done for importing XMLTV/SD downloading, plus the mapping against the channel table.

I dont think you'd be able to reuse that class. I might be able to create you something which is reusable, but I dont have time to do that right now. I dont know how much work you have to do, but if you leave that bit of work til last, I should be able to make something.

Well I tried to wait, and just edited the database but I can't even get the recording service or NPVR to try to record. The database entry gets made and things start ok

Code:

checking: TestRecorder1
enabled and present
has channel
StartStream(6867:TVG CAN)
looking for capture source
checking: TestRecorder1
enabled and present
has channel
Reloading recording schedule
allocating recording target filename: C:\movies\TV Guide\TV Guide_20110731_21000000.ts
About to start recording (931): C:\movies\TV Guide\TV Guide_20110731_21000000.ts

but then..

Code:

Can you post the nrecord.log so I've got some clues where it is crashing?

[mvallevand]

Sure but that log above is where NRecord ends Also NRecord does not seem to call the constructor and neither does NPVR (when running as a recorder) after the first crash.

Can you zip and attach your npvr.db3 file so I can see what the channel and channel mapping look like in the database.

[mvallevand]

Sure. I emptied it but it is otherwise complete. It includes a future recording that do seem to get created properly, until recording time starts. I didn't know what service_type to use so I used zero. On the channels panel it does show up as unknown though.

Sorry, is there any chance you can try to reproduce it again, then post the matching npvr.db3 and nrecord.log? The current log referred to a scheduled recording that wasnt in the database.

In the code it looked like the scheduled recording entry in the database had an invalid capture source ID. I wanted to check if that was really the case.
