+ * 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...
+ *
+ * Typical usage:
+ *
+ * vlc v4l:/dev/video:input=2:norm=pal:size=192x144 \
+ * --sout '#transcode{vcodec=theora,vb=300,acodec=vorb,ab=96}\
