Scenario 5
----------
+Live Stream resampling (to 32KHz) and encoding from FIFO and preparing for DAB muxer, with FIFO to odr-dabmux
+using mplayer. If there are no data in FIFO, encoder generates silence.
+
+ mplayer -quiet -loop 0 -af resample=32000:nowaveheader,format=s16le,channels=2 -ao pcm:file=/tmp/aac.fifo:fast <FILE/URL> &
+ dabplus-enc -l -f raw --fifo-silence -i /tmp/aac.fifo -r 32000 -c 2 -b 72 -o /dev/stdout \
+ mbuffer -q -m 10k -P 100 -s 1080 > station1.fifo
+
+*Note*: Do not use /dev/stdout for pcm oputput in mplayer. Mplayer log messages on stdout.

+Scenario 6
+----------
Wave file encoding, for non-realtime processing
dabplus-enc -a -b $BITRATE -i wave_file.wav -o station1.dabp
