muaz-khan/RecordRTC
RecordRTC is WebRTC JavaScript library for audio/video as well as screen activity recording. It supports Chrome, Firefox, Opera, Android, and Microsoft Edge. Platforms: Linux, Mac and Windows.
RecordRTC is a browser-side JavaScript library that wraps the MediaRecorder API (and several fallbacks) to handle audio, video, screen, canvas, and GIF recording. It targets developers who need in-browser recording without a server-side pipeline. The promise-based handler makes the common case clean to write.
The fallback chain is genuinely useful — StereoAudioRecorder handles cases where MediaRecorder's audio output is unusable, and WebAssemblyRecorder via webm-wasm provides a VP8 encode path when the browser's own encoder is inadequate. The `getSeekableBlob` helper solves a real gotcha: recorded WebM blobs from MediaRecorder lack seek metadata, and this is the fix most people discover the hard way. The directory of self-contained HTML demos is one of the more honest 'show your work' approaches to documentation — you can just open a file and see it run. The SocketIO and PHP upload examples remove a common integration question before it gets asked.
The repo hasn't had a commit since May 2024, and several internals depend on deprecated or removed APIs — WhammyRecorder is broken in modern Chrome (the WASM path is the real replacement but isn't the default). The bundled `webm-wasm.wasm` binary ships as a checked-in blob with no build script, so auditing or updating it requires trusting the author's build environment. There's no TypeScript and no published types, which means in 2026 you'll be writing your own `.d.ts` or living with `any`. Test coverage is minimal and was running on Travis CI, which has been paywalled for open source for years — the test badge in the README is effectively dead.
