-----------------------------------------Sparse notes on A/V Resources management.-----------------------------------------* Default dir for A/V files is /var/fenice/avroot.* Default RTSP port is 1554.* For every A/V resource you need    1) two separate files for audio (MP3) and video (MPEG-1,2),  2) a Source Description (.sd) file for resource description.    Streming clients must be invoked with, e.g:  		$ mystreamingclient rtsp://streamingserver:1554/myvideo.sd  or similar. You can't request plain mpeg or mp3 files, neither for audio-only  nor video-only resources.      See test files in avroot dir for examples.* You can do live mp3-coded streaming using a named-pipe:  1) Create a named-pipe (e.g., mkfifo live.mp3),  2) create an .sd file with the named-pipe as audio content, then  3) feed named-pipe with live-encoded mp3 data.* Suggested encoding tools:  Video: mjpegtools' mpeg2enc  Audio: lame
