DVB-T Radio Support

[imilne]

The graph looks right - the only 'uknown' in there is the NVIDIA Audio Decoder but I'm not sure if it's the cause of the problem. Could you try downloading and registering the MPA Decoder from here...

http://www.free-codecs.com/download/MPA_Decoder.htm

It's the audio decoder which my setup uses so I know it works in the dvb-t radio graphs.

Nope, still nothing but silence I'm afraid.

I thought (after you'd mentioned the nVidia audio) that maybe it was because I only have sound output via spdif, but plugging in some analogue headphones made no difference.

Not looking good is it :-)

[gEd]

Did you test the analogue via some other source to confirm that it works?

Well it has certainly got me confused. Don't worry about the SPDIF thing - it's failing before it even gets to write anything to the buffer file so basically, PVRX2 has nothing to playback anyway.

Could you open the most recent Dvbtr.grf file and just check that it did, indeed, use the MPA Decoder and it isn't still using the nVidia one.

Yep, everything else came out the headphones fine.

Yes, it's showing on the graph as "MPA Decoder Filter", linked from pin3 of MPEG2 Demultiplexer to its "in" and from "out" to "xform in" of the Lame Audio Encoder.

OK - can you confirm...

1. You're logged in with a user account that has write permission to the D:\MyVideos\GBPVR folder on your machine.

2. The version of the lame directshow filter you're using. You can find this out by opening dvbtr.grf with GraphEdit, right-click the lame filter and select Filter Properties then the 'About' tab.

Also, if you want to try a live playback graph, try the following...

1. Open dvbtr.grf with GraphEdit, select the file writer filter (far right named gbnetradio-1.mp3) and use the Delete key to remove it. Do the same for the LAME Encoder filter.

2. Right-click the (now disconnected) 'out' pin of the MPA Decoder and select 'Render Pin'. This should add an audio renderer filter.

3. Right-click the DVBT Network Provider filter and select Filter Properties, then select the DVBT Tune Request tab. For ONID, TSID, SID, CarrierFrequency and SymbolRate, enter the numbers 9018, 16384, 18496, 801834 and 8 repectively.

3. Click 'Submit Request' then OK.

4. On the button bar at the top of GraphEdit, there are Play, Pause, Stop buttons. Click Play and let me know what happens.

1 and 2 were fine.

I couldn't get this part to work. When I right click on the DVBT network provider, it gives me the "the requested property page could not be displayed" error.

I have three tuners, a dual Pinnacle 3010 and a single Nova-T USB2. It's the Nova-T that's usually used for Live TV (bottom of the list), so I'd guess it's probably that being used for the radio too?

IF you do regsvr32 proppage.dll, it should work (I think).

Hmm, I don't see to have that dll with the copy of graphedit I downloaded (using the link you gave).

I'll do a little more digging and see if I can find one that has it.

I've PM'd you with a link to a copy which does.
