HTTP Live Stream (HLS) from RPI camera

Including a web interface with player and commands to start and stop data flow from the source

How to stream from RPI to web throw HTTP

On your RPI

Prereq

• PI with OS Bullseye or latest
• RPI Camera hardware module
• ffmpeg installed

Execution

• Capture and process video command libcamera-vid -t-0 --width 640 --height 480 --framerate 30 --codec h264 --bitrate 500000 -o - | ffmpeg -i - -c copy -f hls -hls_time 4 -hls_list_size 5 -hls_flags delete_segments -hls_segment_filename './stream/segment*%03d.ts' ./stream/index.m3u8

  • libcamera-vid > Captures video from the hardware and encodes it into the desired format (H.264 in this case)
  • ffmpeg > Get the incoming video stream and generates HLS (HTTP Live Streaming) segments and playlist files.

• A simple http server serving static content: This implies that you'll need a basic web server to serve the generated HLS content (.m3u8 playlist and .ts segment files) to clients.

  • In this scenario, the server will manage the start and stop of the video process, interacting with the client through REST and Socket.io for real-time communication.

Client side

• A HLS player (on browser, VLC, ...)
