OK.
In order to get the correct info from a v4l2-ctl --all: Format: Type : VBI Capture Sampling Rate : 27000000 Hz Offset : 248 samples (9.18519e-06 secs after leading edge) Samples per Line: 1440 Sample Format : GREY Start 1st Field : 6 Count 1st Field : 18 Start 2nd Field : 318 Count 2nd Field : 18 Video input : 0 (Tuner 1) Audio input : 0 (Tuner 1) Frequency: 1440000 (90.000000 MHz) Video standard = 0x000000ff PAL-B/B1/G/H/I/D/D1/K Tuner: Capabilities : @@ -881,12 +881,19 @@ bool cPvrDevice::Tune(int freq) { struct v4l2_frequency vf;

I think this don't work. I use freq >180000 because 180000 is the max range for FM. You can also use:
if (radio_fd >= 0) radio else tv

vf.type = V4L2_TUNER_ANALOG_TV;else{log(3, "Changing to RADIO");vf.type = V4L2_TUNER_RADIO;freqaux = freq * 1000;} vf.frequency = (int) ((double) freq * 16.0 / 1000.0 + 0.5);

I patched as follows:
Thanks Jose - that's a great help!

I use this modified code in device.c (pvrinput):
bool cPvrDevice::Tune(int freq) { struct v4l2_frequency vf; int freqaux = freq;
memset(&vf, 0, sizeof(vf)); vf.tuner = 0; if (freq > 180000) vf.type = V4L2_TUNER_ANALOG_TV; else { vf.type = V4L2_TUNER_RADIO; freqaux = freq * 1000; } vf.frequency = (int) ((double) freqaux * 16.0 / 1000.0 + 0.5); if (IOCTL(video_fd, VIDIOC_S_FREQUENCY, &vf) != 0) { log(0, "Error tuning to %d: %s", freq,strerror(errno)); return false; } frequency = freq; return true; }
But I have some problems with radio(pvrinput), and xineliboutput.
The problem I have is that after a while sound is distorted an finally sound stop. There is not any messages in the log. I don't know if is pvrinput or xineliboutput fault.

It looks like this plugin does something wrong with the analog radio
on
the OEM PVR-150 card.
With channels.conf set to: Radio 91ZM:90900:I999C0:C:0:0:300:305:A1:12003:1:1007:0
v4l2-ctl --all looks like this:
Audio input : 0 (Tuner 1) Frequency: 1454 (90.875000 MHz) Video standard = 0x000000ff PAL-B/B1/G/H/I/D/D1/K Tuner: Capabilities : 62.5 kHz multi-standard Frequency range : 44.0 MHz - 958.0 MHz Signal strength : 0% Current audio mode : mono Available subchannels:
Where ivtv-radio -f90 looks like this:
Audio input : 0 (Tuner 1) Frequency: 1454400 (90.900000 MHz) Video standard = 0x000000ff PAL-B/B1/G/H/I/D/D1/K Tuner: Capabilities : 62.5 Hz stereo Frequency range : 65.0 MHz - 108.0 MHz Signal strength : 50% Current audio mode : stereo Available subchannels: stereo
it appears pvrinput isn't setting the right audio mode/sub channels
etc??
Any ideas?
PS. It looks like analogradio plugin is no longer supported? Is
also
doesn't support ALSA.
?
I've asked this before, last year, but never had a response.
How do I configure radio channels in VDR.
My channels.conf has:
Classic Hits:90000:I999C0:C:0:0:300:305:A1:12003:1:1006:0
But I think I'm picking up the wrong device, as I hear no audio. I have a single PVR-150 with ivtv and the following devices:
/dev/video0 /dev/video24 /dev/video32
When I do a 'ivtv-radio -f90000' I see: aplay -f dat < /dev/video24 #which works
So....what should my Parameters be??
C0 - Input 0 C12 - Input 1 C23 - Input 2 C34 - Input 3 C45 - Input 4 C56 - Input 5 C67 - Input 6 C78 - Input 7 C89 - Input 8 C999 - Input 9
Thanks - in advance!
