Windows FM Radio support in v5.

I can get ffmpeg to bring up the tuner dialog, and then get a station locked in, but when running the ffplay with -i audio, it errors out with:
"could not render stream to connect pins0B f=0/0"

If I run the ffplay line with -i=video, it brings up a blue video screen, but does not error out.

ffplay shouldn't give video if you use -vn

Perhaps run https://github.com/sub3/NextPVR/wiki/FilterCheck and zip and post the file it makes. Maybe sub can give you hints based on that.

Here is the filters scan.

Ok I don't know how to specify a tuner. It is a bit of a waste since I don't think you can use one tuner for video and one for FM, but I may be wrong. Maybe sub can help, but I'm done. What is wrong with Internet Radio or are you just experimenting?

Just experimenting. Since the hardware was there, thought I would try to utilize it. I remember it worked back in the Media Center days out of the box. Thanks for taking a look.

I haven't read this whole thread, but in case it wasn't already mention...

I'm pretty sure only one of the two tuners in HVR-22xx device expose FM radio. It may be a case of using the wrong one.

There are two other parameters to try -video_device_number and -audio_device_number I guess the default is 0 so maybe try 1.

I was finally able to obtain a output of the fm tuner with the following:

ffmpeg -show_analog_tv_tuner_dialog true -f dshow -crossbar_audio_input_pin_number 1 -crossbar_video_input_pin_number 0 -i video="Hauppauge WinTV-7164 Analog Capture":audio="Hauppauge WinTV-7164 Analog Capture" -vn test.mp2

How would I incorporate this into an AnalogRadio.bat file that might work with the -extra in NPVR? I had to do the -show_analog_tv_tuner true in order to set the input to FM, source to antenna, and channel to a known good frequency.

You can't have a UI component in there, you need to use the vlc command for tuning or figure out how to use vlc to do everything in one command.

Will work with vlc to see if I can get it to tune, as both examples in post #101 and post #104 (for tuning with vlc) don't seem to work with my setup.
