CCapture 2.0.0 — ground-up rewrite

Highlights

  • WebCodecs-first MP4 (H.264/AV1) & WebM (VP9/VP8/AV1) — hardware-accelerated, back-pressured
  • GPU (WebGL2) or CPU motion blur, auto-selected
  • Frame-accurate audio: offline analysis (renderAudioFrames) + AudioBuffer muxing (AAC/Opus)
  • Frame-stepped <video>/<audio> capture; async/await throughout
  • Modular: CCapture = TimeWarp (clock) + FrameWrap (capture/encode), each usable alone
  • Pluggable encoders (FrameEncoder / BatchEncoder, registerEncoder)
  • ESM from source, UMD global build, bundled TypeScript types

Breaking changes (see the README's "Migrating from CCapture 1.x")

  • CCapture is now a class composing FrameWrap + TimeWarp; the engine role is now FrameWrap
  • Default format is mp4 (was webm); save() downloads by default
  • Removed ffmpegserver / webm-mediarecorder; gif worker gone (uses gifenc)

Upgrade / CDN notes

  • 1.x is preserved on the 1.x branch and npm ccapture.js@1 — pinned users are unaffected
  • ⚠️ Unversioned CDN embeds of the old bundle (unpkg.com/ccapture.js/build/CCapture.all.min.js) will 404 on v2. Pin @1, or use the v2 global: https://cdn.jsdelivr.net/npm/ccapture.js@2/build/ccapture.umd.min.js
