Windows FM Radio support in v5.

There is no point in trying anything without getting that ffplay line command line working. It sounds like the vlc line isn't tuning which can by tricky.

Did you take out -v panic and see any other errors

I'm not really seeing any other errors.

edit: after taking the screenshot and closing the window, I get these errors:

If you aren't getting audio with the -v panic added using ffplay that means the tuning line with vlc isn't working. You will just have to play around with it you said you had it working. If you tune with WinTV you can probably comment out the first line of the batch file to confirm that audio is working.

I wish there was an easier way to tune, which is why I think that it is easier just to use internet radio.

Could you paste in the contents of your AnalogRadio.bat file. I just confirmed everything is working here with a Hauppauge tuner.

Sure, no problem:

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

Can you explain what the two separate lines are supposed to do?  If I run just the ffmpeg line, it loads up and then shows trash on the screen, which I assume is the digitized audio feed.

I think I also have an old Happauge 955 in the basement somewhere.  I can give that a shot tomorrow, if you think it would be worth it?

Thank you for all of your help, by the way.  I appreciate it.

The first one tunes the second plays. The output from the batch file is audio streaming so don't run it as is that is why I test it via ffplay

You might need to manually tune in VLC to find out pin numbers, I don't think a Hauppauge tuner would be easier to figure out.

Looking at your batch file you might want to try changing :dshow-adev="AVerMedia USB Polaris Analog Capture" to :dshow-vdev="AVerMedia USB Polaris Analog Capture" If you followed https://forums.nextpvr.com/showthread.ph...#pid539810 and you got the tuner I note that is the video device. Also maybe change :dshow-amtuner-mode=2 to 3

So I gave up with the AVermedia Card, since it was behaving weirdly in VLC.  I switched to the Hauppauge Q955 another guy started to test with earlier in this thread, but there is no confirmation he ever got it working.

I can now get a white screen (video) and the proper audio inside of VLC.  In the advanced options, I can see the config working inside of VLC is the following:

:dshow-vdev=Hauppauge Cx23100 Video Capture :dshow-adev=Hauppauge Cx23100 Video Capture  :dshow-aspect-ratio=4\:3 :dshow-chroma= :dshow-fps=0 :no-dshow-config :dshow-tuner :dshow-tuner-channel=0 :dshow-tuner-frequency=0 :dshow-tuner-country=0 :dshow-tuner-standard=0 :dshow-tuner-input=0 :dshow-video-input=-1 :dshow-video-output=-1 :dshow-audio-input=-1 :dshow-audio-output=-1 :dshow-amtuner-mode=2 :dshow-audio-channels=0 :dshow-audio-samplerate=0 :dshow-audio-bitspersample=0 :live-caching=300

I still cannot for the life of me get ffmpeg to produce audio via the batch file.  

Any last thoughts before I bag this idea?  My updated file is this:

@echo off
"C:\Program Files\Videolan\VLC\vlc.exe" -I dummy --stop-time 1 --no-audio --no-video --no-sout-video dshow://  :dshow-vdev="Hauppauge Cx23100 Video Capture" :dshow-adev="Hauppauge Cx23100 Video Capture" :dshow-tuner-frequency=%1 :dshow-tuner-input=0 :dshow-amtuner-mode=2 vlc://quit
"C:\Program Files\NextPVR\Other\ffmpeg.exe" -v panic -f dshow -i audio="Hauppauge Cx23100 Audio Capture" -acodec aac -ab 198000 -f mpegts -


For the ffmpeg line, I've tried both the Audio and Video value for the capture device.  I never get sound output with ffmpeg, regardless of what I try.

[mvallevand]

You never will get sound with ffmpeg. If you tune with VLC and stop VLC what about

ffplay -f dshow -i audio="Hauppauge Cx23100 Audio Capture"

Doing that launches a small black window, but still plays no sound.  I also tried the Video capture value - nada.
