- latency increases strongly when vlc or cvlc is used
direct udp stream
- Raspi with camera
raspivid -a 12 -t 0 -w 1280 -h 720 -hf -ih -fps 30 -o udp://192.168.1.10:5000 -a 12 # annotate -t 0 # timeout disabled (default=5s) -w 1280 # width -h 720 # height -hf # horizontal flip #-vf # vertical flip -ih # insert inline headers to stream -fps 30 # frames per second -0 udp://192.168.1.10:5000 # send stream to ip:port
- Raspi with monitor
omxplayer --win 0,0,800,480 udp://@:5000 -win 0,0,800,480 # position of video window
direct tcp stream
- Raspi with camera

direct tcp stream with netcat
