Read doc/README.radio. /dev/video24 produces a PCM stream at 48 kHz. So
you can play it directly using 'aplay -f dat </dev/video24' for
example.
Recording: cat /dev/video24 >test.pcm
Now we're getting somewhere! Thanks for putting up with my ignorance.
fmscan shows 90.1 at 50.%. So, I do:
fm -d /dev/radio0 90.1 65536
(Radio tuned to 90.10 MHz at 100.00% volume)
cat /dev/video24 > /tmp/test.pcm
I waited a few minutes, and did a ctrl-C. However, looking at the resultant test.pcm in a hex editor shows it as nothing but zeros. The same is true regardless of which channel I select.
ivtv-radio -d /dev/radio0 -f 90.1 -c "cat %s > /tmp/foob.pcm"
This time, I get a repeated pattern of 00 and FF in the file, but no useful information, with the same results on different channels.
Any more tips or advice?
