3. Install requirements

pip3 install -r requirements.txt

4. Install dependencies

sudo apt install vlc libav-tools

5. Create script to livestream:

cd ~
echo "raspivid -t 0 -vf -hf -w 640 -h 480 -fps 15 -b 1000000 -o - | cvlc -vvv stream:///dev/stdin --sout '#standard{access=http,mux=ts,dst=:8090}' :demux=h264" > stream.sh
chmod a+x stream.sh

• -t 0 : no timeout (stream indefinitely)
• -vf: vertical flip (flip video vertically)
• -hf1: horizontal flip (flip video horizontally)
• -w 640 -h 480: video size 640x480 px
• -fps 15: frames per second
• -b 1000000: bit rate
• -o -: output to STDIN
• access=http: livestream can be accessed via HTTP
• dst=:8090: destination is localhost port 8090
