Movi Player for VS Code

Play modern video formats directly inside VS Code — MKV, HEVC, AV1, HDR, WebM, MOV, TS and more, including formats VS Code can't natively handle.

100% local. Nothing uploaded. Powered by FFmpeg WebAssembly + WebCodecs hardware decoding.

Usage

Single-click any video file in the Explorer (.mp4, .mkv, .webm, .mov, .avi, .ts, .flv, .wmv, .m4v, .3gp, .mpg, .mpeg, .m2ts, .hevc, .265) — opens directly in Movi Player
Right-click any file → "Open With…" → "Movi Player" — works for any extension (try with .iso, .vob, etc.)
Command Palette (Cmd+Shift+P):
- Movi: Open Video File — file picker
- Movi: Open Video from URL — paste a remote video URL

Containers: MP4, MKV, WebM, MOV, TS/M2TS, AVI, FLV, WMV, MPG/MPEG, 3GP

Video codecs: H.264, HEVC (H.265), AV1, VP9, VP8 — hardware-accelerated where available

Audio codecs: AAC, Opus, FLAC, MP3, AC3, Vorbis — software fallback

HDR: HDR10 / HLG / Dolby Vision profile 8 (on supported displays)

Setting	Default	Effect
`movi.ambientMode`	`true`	Color glow around the video
`movi.resume`	`true`	Resume playback from last position

VS Code's webview sandbox restricts a few features that work in the Chrome extension:

Fullscreen is disabled (Permissions-Policy denies requestFullscreen in webviews)
Picture-in-Picture is hidden (same reason)
SharedArrayBuffer is unavailable, so FFmpeg runs single-threaded — slightly slower demuxing on very large files (8K HDR streams). Hardware video decode is unaffected.

For full feature parity (including fullscreen + PiP), use the Chrome extension or movi-player web app.

Everything runs locally inside VS Code's sandboxed webview. No uploads, no telemetry, no servers. Your video files never leave your machine.
