[MPlayer-dev-eng] [PATCH] Radio support

Tue Aug 22 20:52:25 CEST 2006


Hi, All

I have prepared new version of my patch with trivial changes:

1. Code synchronized with current svn (new stream folder and so on)
2. Some missed MSGT_TV constant replaced with MSGT_RADIO
3. Increased loop in grab_audio_frame to make sure cache buffer filled up successfully.

Can anybody review it and make decision about commit?

Thanks.

+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
+&quot;_&quot; character.

+<para>
+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. 
+</para>
+</listitem>
+
+<listitem>
+<para>
+<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)

+.B \-radio <option1:option2:...> (Radio only)
+This options set variaous parameters of radio capture module
+For listening radio with MPlayer use 'radio://<frequency>' 
+(if channels option is not given) or
+'radio://<channel_number>' (if channels option is given) as
+a movie URL. To start grabbing subsystem, please use 
+radio://<frequency or channel>/capture. If capture keyword is not given
+your can listen radio using line-in cable only. Using capture
+to listening is not recommended due to synchronization problems, which
+makes this process uncomfortable.
+.sp 1
+Available options are:
+.RSs
+.IPs device=<value>
+radio device to use (default /dev/radio0)
+.IPs driver=<value>
+radio driver to use (default v4l2 if available, otherwise v4l). Currently supported
+v4l and v4l2 drivers.
+.IPs volume=<0..100>
+sound volume for radio device (default 100)
+.IPs channels=<frequency>\-<name>,<frequency>\-<name>,...
+Set channel list.
+Use _ for spaces in names (or play with quoting ;-).
+The channel names will then be written using OSD, and the slave commands
+radio_step_channel and radio_set_channel will be usable for
+a remote control (see LIRC).
+If given, number in movie URL will be treated as channel position in
+channel list.
+.br
+.I EXAMPLE:
+radio://1, radio://104.4, radio_set_channel 1
+.IPs adevice=<value> (with radio capture enabled)
+Name of device to capture sound from. If not given capture will be
+disabled, even if capture keyword in URL used. For alsa devices use it 
+in form hw=<card>.<device>. If device
+name contain '=' module will use ALSA to capture, otherwise - OSS.
+.IPs arate=<value> (with radio capture enabled)
+Rate in samples per second (default 44100).
+.br
+.I NOTE:
+When using audio capture set also 
+-rawaudio rate=<value> option with the same value as arate. If
+you have problems with sound speed (too quickl) try to play with 
+different values of rate (e.g. 48000,44100,32000,...).
+.IPs achannels=<value> (with radio capture enabled)
+number of audio channels to capture
+.RE
+.
+.TP
 .B \-tv <option1:option2:...> (TV/PVR only)
 This option tunes various properties of the TV capture module.
 For watching TV with MPlayer, use 'tv://' or 'tv://<channel_number>'
