video-player

Video Player

Plays video files on an HTML canvas — frames are decoded in Go via ffmpeg, sent to the browser, and painted on a <canvas> element. No <video> tag involved.

Requirements

• ffmpeg installed and in your PATH

Usage

go run ./examples/video-player/ -video /path/to/video.mp4

With godom env vars:

GODOM_PORT=8099 GODOM_NO_AUTH=1 go run ./examples/video-player/ -video /path/to/video.mp4

Controls

• Play / Pause — toggle playback
• Stop — reset to first frame
• -5s / +5s — skip backward or forward

How it works

1. Go shells out to ffmpeg to decode the video into JPEG frames at 24fps
2. Frames are stored in memory and base64-encoded as plugin data
3. The JS plugin (20 lines) decodes each JPEG and draws it on canvas via drawImage
4. All playback logic (play/pause/stop/seek) lives entirely in Go
