Snazim se pomoci ffserver vytvorit mjpeg stream, ktery krmim rtsp streamem.
Pokud si vsak otevru mjpeg stream, dostavam snimky, ktere jsou ve sve spodni casti rozpadle.
FFserver:
Port 8090
# bind to all IPs aliased or not
BindAddress 0.0.0.0
# max number of simultaneous clients
MaxClients 4
# max bandwidth per-client (kb/s)
MaxBandwidth 10000
# Suppress that if you want to launch ffserver as a daemon.
