Great hopefully that will help some others. It is not clear to me what will happen if you use this device as FM and ATSC even when you don't use them at the same time so I would avoid that, or at least test that.

Hopefully so. I have switched back and forth from FM and ATSC in kodi with no issues so far. I also was able to leave out the -crossbar_audio_input_pin_number 3 and the -vn. So it seems the issue was not changing frequency to channel. Not sure why it didn't work when I first tried though.

I got a WinTV PVR USB2 off ebay (for $25 CDN with shipping) and while it doesn't support ATSC FM works. It is the first device I've found that works well in Linux too. The Extra for Windows was a bit tricky for whatever reason I can't directly run the same command for VLC in the batch file that works from the command prompt so I had to start it and kill it. Of course this also means that VLC can't be running at the same time (you could copy vlc.exe to another name)

AnalogRadio.bat would be

Code:

@echo off
start /b "" "C:\Program Files\Videolan\VLC\vlc.exe" -I dummy --dummy-quiet --no-video --no-audio --no-sout-all dshow:// :dshow-adev="Hauppauge PVR USB2 AVS Video Capture" :dshow-tuner-channel=%1  :dshow-tuner-input=1 :dshow-amtuner-mode=2 --stop-time 1  vlc:quit
"C:\Program Files\NextPVR\Other\ffmpeg.exe"  -v panic -re -f dshow -i audio="Hauppauge PVR USB2 AVS Video Capture" -vn -acodec aac  -af "aresample=async=1"   -ab 198000 -f mpegts -
taskkill  /im vlc.exe /f > NUL

Sorry to ping an old thread, but I have been trying to get this working with a Hauppauge WinTV-HVR-2250 which has an analog fm tuner. As this thread was based upon Version 5 of NextPVR, I am curious if most of the instructions in the thread are usable in Version 6.1.1.221106? I have installed WinTV (v7) and that plays the analog fm just fine. I can get the ffmpeg show_analog_tuner_dialog, and can select frequency, FM, antenna, but when I try and output this to a file, it errors with no stream. If I am silly trying to do this in Version 6 NextPVR, please let me know. Thanks.

[mvallevand]

Yes. To avoid confusion I know just say NextPVR and refer to the older version as v4.

I have written a new dotnet installer once you get the ffmpeg line working. It works much better with the cheap SDR radio devices too no config of VLC or FFmpeg needed.

Thanks for the reply. So, I should continue playing around with the ffmpeg tuner settings until I get a good output before proceeding (varying the parameters in the tuner dialog). Directing the output to a .wav file as a test?

[mvallevand]

Yes, figure the device that is yours, and play with the crossbar settings too more then the setting on the dialog.

Not having much luck changing the -crossbar_audio_input_pin_number in the AnalogRadio.bat (taken from post #101). Tried pin numbers 0 thru 4 with no output. Maybe the :dshow-tuner-input or :dshow-antuner-mode numbers are wrong for my capture card? Here is the AnalogRadio.bat I am using for testing:

@echo off
"C:\Program Files\Videolan\VLC\vlc.exe" -I dummy --stop-time 1 --no-audio --no-video --no-sout-video dshow:// :dshow-adev="Hauppauge WinTV-7164 Analog Capture" :dshow-tuner-channel=%1 :dshow-tuner-input=2 :dshow-amtuner-mode=2 vlc://quit
"C:\Program Files\NextPVR\Other\ffmpeg.exe" -v panic -f dshow -crossbar_audio_input_pin_number 3 -i audio="Hauppauge WinTV-7164 Analog Capture" -vn -acodec aac -ab 198000 -f mpegts -

[mvallevand]

Figure out how to tune using the ffmpeg to lock on a channel and then use ffplay to audio and then work backwards is much better than using the batch file commands.
