OK.
In order to get the right tuning values from 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 : 62.5 Hz stereo
Frequency range : 65.0 MHz - 108.0 MHz
Signal strength : 50%
Current audio mode : stereo
Available subchannels: stereo
I patched as follows:
@@ -881,12 +881,19 @@
bool cPvrDevice::Tune(int freq)
{
struct v4l2_frequency vf;
+ int freqaux = freq;
memset(&vf, 0, sizeof(vf));
vf.tuner = 0;
- vf.type = V4L2_TUNER_ANALOG_TV;
+ if (freq < 88000000)
+ 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);
-
if (IOCTL(video_fd, VIDIOC_S_FREQUENCY, &vf) != 0)
{
log(0, "Error tuning to %d: %s", freq, strerror(errno));
and my channels.conf looks like this:
Radio Classic Hits:90000000:C0:C:0:0:300:305:A1:12003:1:1006:0
It's tuning ok now - but I still get no audio.
I'm struggling with this. I somehow need the plugin/VDR to listen to
effectively tune and then do an equivalent of:
aplay -f dat < /dev/video24
how do I do this??
