/*****************************************************************************
* Some Comments:
*
- * o this only works for ogg streams, and there's no checking about that yet.
- * o i have lots of problems with audio, but i think they are not caused
- * by this patch
- * o there's a memleak somewhere, quite huge. i'm unsure if its somewhere
- * in libshout, in vlc or even in this patch...
+ * - this only works for ogg and/or mp3, and we don't check this yet.
+ * - MP3 metadata is not passed along, since metadata is only available after
+ * this module is opened.
*
* Typical usage:
*
* vlc v4l:/dev/video:input=2:norm=pal:size=192x144 \
* --sout '#transcode{vcodec=theora,vb=300,acodec=vorb,ab=96}\
- * :std{access=shout,mux=ogg,url=localhost:8005}'
+ * :std{access=shout,mux=ogg,dst=localhost:8005}'
