Describe the bug Just downloaded and extracted the zip on my pi3 b+ and got this message. streaming works over LAN. Hope I can get this software to work as it seems really awesome!

To Reproduce downloaded the zip. extracted and ran python app.py this is on a rpi 3 cat /etc/debian_version gives 12.5

libcamera-vid --list-cameras

    Modes: 'SGBRG10_CSI2P' : 640x480 [58.92 fps - (16, 0)/2560x1920 crop]
                             1296x972 [43.25 fps - (0, 0)/2592x1944 crop]
                             1920x1080 [30.62 fps - (348, 434)/1928x1080 crop]
                             2592x1944 [15.63 fps - (0, 0)/2592x1944 crop]

Expected behavior I expected it to run and not crash so that I could open the webapp on a browser

Screenshots console output is probably better:

I can stream the video to VLC (client) with this command: rpicam-vid -t 0 --inline -o - | cvlc stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/stream1}' :demux=h264 just to verify that the cam works and the networking etc. Might just be the case that my pi is not powerfull enough? rpi 3 b+
