This server is part of the Robobot repository at svn/robobot/stream_server and should be started at boot-time. (see ~/on_reboot.bash)
Or try:
cd /home/local/svn/robobot/stream_server /usr/bin/python3 stream_server.py
Watch result using a browser
Using the IP of the robot (in this case, robot Coco), the robot camera image can be viewed at this address:
Change configuration
Change the configuration in the streamer source code:
/home/local/svn/robobot/stream_server/stream_server.py

<img src="stream.mjpg" width="820" height="616" /> </body>
Camera configuration
Select the matching line to the settings above:
picam2 = Picamera2()
#picam2.configure(picam2.create_video_configuration(main={"size": (1296, 972)},controls={'FrameDurationLimits': (200000, 200000)}))
picam2.configure(picam2.create_video_configuration(main={"size": (820, 616)},controls={'FrameDurationLimits': (200000, 500000)}))
#picam2.configure(picam2.create_video_configuration(main={"size": (1296, 972)},controls={'FrameDurationLimits': (200000, 500000)}))
#picam2.configure(picam2.create_video_configuration(main={"size": (640, 480)},controls={'FrameDurationLimits': (200000, 500000)}))
#picam2.configure(picam2.create_video_configuration(main={"size": (320, 240)},controls={'FrameDurationLimits': (200000, 500000)}))
Reboot or restart to see the effect.
