Xine can't play FIFO

[Debsu]

Hi,

I want to feed any .mp3 file to Xine through FIFO. Thus, I wrote an application which reads an .mp3 file and sends the data to a FIFO. Another application creates an Xine stream and passes the FIFO name to xine_open(). But each time it gives me the following error:
 XINE_ERROR_NO_DEMUX_PLUGIN

Any help is appreciated.
Regards,
Deb
