Сервер ретрансляции:

cvlc http://99.99.99.99:8083/stream.flv --ipv4-timeout=1000  --loop --sout '#duplicate{dst=std{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=0.0.0.0:8092/stream.flv},dst="transcode{vcodec=none,acodec=mp4a,ab=96}:std{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=0.0.0.0:8093/stream.flv}"}'

Скрипт запуска:

#/usr/sbin/bash
echo "**********************************************************"
echo "Для того, чтобы прекратить трансляцию -- закройте ЭТО окно! "
echo "**********************************************************"

echo "**********************************************************"
echo "Если Вы видите эту надпись, но трансляция не идет"
echo "-- закройте ЭТО окно и запустите трансляцию снова."
echo "**********************************************************"

Сам mosaic.vlm для одной камеры (можно было бы обойтись и без мозаики, но так было проще):
