gocv-to-webrtc: Streaming Live Webcam Video to Browser with GoCV, FFmpeg, and Pion WebRTC
By

Front-window bakery material. Catches the eye, delivers the goods.
Summary
This article describes a project called "gocv-to-webrtc" that demonstrates how to stream live webcam video to a browser using GoCV for camera capture, FFmpeg for real-time VP8 encoding, and Pion WebRTC for media transport. It serves as a starting point for building computer vision projects viewable via WebRTC. The implementation covers four key pieces: capture (GoCV webcam access), encode (FFmpeg VP8 encoding in IVF format), stream (Pion WebRTC transport), and frontend (minimal HTML/JS page for WebRTC negotiation).

This project could be a starting point to building a computer vision project that is viewable via WebRTC.
Capture: Uses GoCV to access a webcam and read raw BGR frames.
Encode: Pipes raw frames into ffmpeg for VP8 encoding in IVF format.
Stream: Uses Pion WebRTC to send encoded video frames to a browser client.
