MediaPortal generates an invalid filter graph for my tuner (1 Viewer)

[ijourneaux]

Your observation that the tuners are slightly different is really interesting as both tuners are in one device. The AVC-3610 is a USB based dual tuner.

I will run though the same thing I did this morning on both tuners when I get back home tonight. A couple of hours at the most.

Take Care.

Ahhhh, should have realised that - was just in a bit of a rush to get to work this morning. :sorry:

The capture filter "device paths" (which is what I'm using to uniquely identify the 3610) are:

@devicenp:\\?\usb#vid_03f3&pid_0091#016150001290#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\capture
@devicenp:\\?\usb#vid_03f3&pid_0093#026150001290#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\capture

The "@devicenp:\\?\usb" part tells me I'm dealing with plug-and-play USB devices. "vid" stands for vendor ID - I'm guessing 03f3 must be Adaptec's ID. The bit after that was the bit I was concerned about, because apparently it is meant to be the product ID. I guess in this case it is just used to differentiate between the tuners. The next part I have no idea about and the last part ("#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\capture") just tells me the filters are capture filters.

As I say, probably a false alarm on my part, so I'll submit the patch for review when I get home this evening, however I think it would still pay to double check the second tuner if you can.

Thank you once again for your patience,

Ok. Ran the test with the dll file you uploaded thismorning. You could preview both tuners. I installed the latest version you uploaded. It worked for te first tuner but not the second. First log is with the first dll. the second with the last one.

They are in fact different mainly (I suppose) because one of them supports the FM Tuner which, although even after applying the patch, it is not working (the FM radio tuner I mean).

Hi xfx

Thanks for commenting - I didn't think you still had your tuner after your response to my PM...
It looks like I made a sloppy mistake in the "final" patch oops::sorry, so make sure you're using the "debug" version from -->here<--. If FM still doesn't work with that then please post logs so that I can take a look.

Hello mm1352000,

I still have the tuner but I'm no longer using it to watch TV -- mainly it serves as my IR receiver to control MP.
As for ther debug version of the DLL: should I be using MP 1.2? (Because right now I'm using 1.1.3).

 

[mm1352000]

Hi again xfx

If you're on 1.1.3 then you'll need to use the patch from here (which I guess is the one you're already using?). I think before you do anything else it would be helpful to see some logs for the FM problem. Please use the watchdog with option 3 to start MP, attempt to start listening to an FM channel, observe the failure, close MP to generate the log zip file, and then post the zip file here.

PS: I have been asked to commit the patch for the original problem.

Hello mm1352000,

Yes, I'm on 1.1.3 and I'm using the patch you posted on this thread.
The thing is that I cannot use MP to try to listen to an FM station because the TvSetup program does not find any stations (and I can confirm the tuner is working because WMC is working correctly).
Would it help if I sent you some logs from the SetupTv application? And, where should I find those?

Again, thank you SO much for all your help.

Ahhh, okay.

Yes, logs would be very helpful I think. If the TV Server is installed on the same machine as MediaPortal then open up TV Server configuration and do a full scan, and then use the watchdog with option 3 (export all currently present logs) to create a zip file that contains all the important logs and information. There is excellent information about the watchdog -->here<--.

Otherwise, if your TV Server is on a separate computer from MediaPortal then you can find the logs in C:\ProgramData\Team MediaPortal\MediaPortal TV Server\log\ (for Windows Vista and Windows 7). That is a hidden folder though, so the easiest way to get there is to open TV Server configuration and click on the "open log directory" link in the top left hand corner (as shown in the screenshot -->here<--). Delete all the files in there, then do the FM scan, then zip up all the files that are created during the scan, and post the zip file here.

Again, thank you SO much for all your help.

No problem.

Ok... here it is. I really hope it helps.
