I'm attempting to transcode NASA tv tp my WD Live mediaplayer using Mediatomb. So far I've managed to setup the link using the web iterface with the following attributes:

URL http://playlist.yahoo.com/makeplaylist.dll?id=1368163
Protocol http-get
Class object.item.videoItem
Mimetype video/x-ms-asf

In config.xml I've added the following:

<transcode mimetype="video/x-ms-asf" using="vlcmpeg"/>

and

<agent command="vlc" arguments="-I dummy -sout '#transcode{venc=ffmpeg,vcodec=mp2v,vb=2048,fps=30,aenc=ffmpeg,acodec=mpga,ab=192,samplerate=44100,channels=2}:std{access=file,mux=ts,dst=%out}' %in vlc:quit"/>

When I attempt this command from the command line as the mediatomb user I see a file generated that I can play using mplayer or VLC viewer.

When I make a fifo using mkfifo and I do the above command at the command line as the user it also works (but uses the fifo instead of a file)

When I select it from my media player I see a named pipe (fifo) created and vlc starts but for some reason there is no data in the fifo. As well it appears as though several vlc instances get created and destroyed as there may be more than one fifo created.

I have checked these vlc/fifo comos with mplayer as well just in case my player is just being stupid but it appears that while the fifo is there (mplayer connects to it no problem) there is not data coming though.

Am I missing something real obvious?

My version of mediatomb was compiled with the following options:
