Raspberry Pi/Camera streaming

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

raspivid -a 12 -t 0 -w 1280 -h 720 -vf -ih -fps 30 -l -o tcp://0.0.0.0:5000

• Raspi with monitor

omxplayer --win 0,0,800,480 tcp://192.168.1.20:5000

• vlc with monitor

tcp/h264://192.168.1.20:5000

rtsp stream (big latency)

• Raspi with camera

raspivid -t 0 -n -b 1000000 -g 30 -ih -pf baseline -w 640 -h 480 -fps 30 -o - | cvlc -v stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264

• Raspi with monitor

omxplayer --win 0,0,800,480 rtsp://192.168.1.20:8554/

• vlc with monitor

rtsp://192.168.111.182:8554/

dual output (direct low latency + rtsp big latency)

• Raspi with camera

mkfifo video.stream
raspivid -a 12 -t 0 -w 1280 -h 720 -hf -ih -fps 30 -o - | tee video.stream | cvlc -v stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264 | nc 192.168.1.20 5000 < video.stream

• Raspi with monitor

mkfifo video.stream
nc -l -p 5000 > video.stream | omxplayer --win 0,0,800,480 video.stream

gstreamer

• apt install gstreamer1.0-tools gstreamer1.0-plugins-bad gstreamer1.0-plugins-good gstreamer1.0-libav
