[MPlayer-dev-eng] [PATCH] Radio support for MPlayer
Vladimir Voroshilov
voroshil at univer.omsk.su
Sun Jul 16 09:03:20 CEST 2006
This is updated version of patch.
Changes:
1. Removed dirty hack in demux_rawaudio.c
2. Removed possible endless loop in grab_audio_frame
3. both v4l and v4l2 can be compiled in (runtime switched by 'driver' parameter)
4. removed 'preload' parameter (due to duplicating MPlayer's -cache)
5. removed duplicated comments in stream_radio.h
6. made doxygen comments for all radio parameters

+Explanation: using this option, only the 104.4 and 103.9 radio stations

+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)

+For listening radio with MPlayer use 'radio://<frequency>'

+When using audio capture set also
+-rawaudio rate=<value> option with the same value as arate. If
