Use the <option>channels</option> option. An example:
|
|
<screen>-radio channels=104.4-Sibir,103.9-Maximum</screen>
|
|
Explanation: using this option, only the 104.4 and 103.9 radio stations
|
|
will be usable, and there will be a nice OSD text upon channel switching, displaying the
|
|
channel's name. Spaces in the channel name must be replaced by the
|
|
"_" character.

There are several ways of capturing audio. You can grab the sound either using
|
|
your sound card via an external cable connection between video card and line-in,
|
|
or using the built-in ADC in the saa7134 chip. In the latter case, you have to
|
|
load the <emphasis role="bold">saa7134-alsa</emphasis> or
|
|
<emphasis role="bold">saa7134-oss</emphasis> driver.

<application>MEncoder</application> cannot be used for audio capture, because it
|
|
requires video stream to work. So your can either use arecord from ALSA project or
|
|
use <option>-ao pcm:file=file.wav</option>. In second case you will not hear any sound
|
|
(except you using line-in cable and have switched line-in mute off)
