Alsa? Or how could I capture analog radio/tv

(1/3) > >>

Judgin:
Hi guys,

could you help me with capturing analog FM radio? As there is no alsa device (arecord -l shows my sound card) I cannot capture sound...It seems to me, that the same problem will be with analog TV, however I didn't try yet.

Regards, Judgin

Sundtek:
quite easy:


--- Zitat ---cat /dev/radio0 | lame > fmradio.mp3

--- Ende Zitat ---

if you do a cat on radio0 it will also output the WAV header, so lame automatically knows which format the input data is.

Judgin:
Thanks, will try this solution) Looks really easy)

Sundtek:
If you do the cat on the dsp device the output will be header less.


--- Zitat ---cat /dev/dspN | aplay --format=S16_LE --rate=48000 -c 2
or
cat /dev/radioN | aplay

--- Ende Zitat ---

where N is revealed by /opt/bin/mediaclient -e

Judgin:
Hmmm...I've got problems(((


--- Code: ---cat /dev/dsp0 | aplay --format=S16_LE --rate=48000 -c 2
aplay: playback:2455: read error

--- Ende Code ---

And this also doesn't work...exits after 1-2 secs.

--- Code: ---cat /dev/radio0 | aplay
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

--- Ende Code ---
