RecordRTC is a browser-focused WebRTC JavaScript recording library. Its core purpose is to record audio, video, screen content, Canvas 2D/3D animations, and GIFs inside web applications. It provides both Promise-based examples and traditional callback-style usage. Developers can obtain a MediaStream via getUserMedia, start and stop recording, and then save the result as a Blob or trigger a download.
In terms of functionality, RecordRTC covers multiple recorder types, including MediaStreamRecorder, StereoAudioRecorder, WebAssemblyRecorder, CanvasRecorder, GifRecorder, and WhammyRecorder. Configuration options include mimeType, bitrate, timeSlice, audio sample rate, number of channels, Canvas dimensions, frame rate, and more. The API is fairly complete, supporting operations such as startRecording, stopRecording, pauseRecording, resumeRecording, getBlob, toURL, getDataURL, save, writeToDisk, and getFromDisk. It also provides global utilities such as getSeekableBlob, invokeSaveAsDialog, and DiskStorage.
The documentation lists capabilities across Chrome, Firefox, Opera, Edge, and Safari on Windows, macOS, Ubuntu, Android, and iOS, as well as codec support for VP8, VP9, H264, MKV, OPUS, VORBIS, PCM, and others. Integration options include the official CDN, cdnjs, NPM, and bower. On the ecosystem side, the page links to the GitHub Wiki, Releases, Issues, and StackOverflow tags, and mentions usage resources for Angular2, React.js, Video.js, and Meteor. The documentation focuses on APIs, configuration options, and examples, which is enough for developers to get started, but production-grade compatibility and exception handling still need to be validated independently.
RecordRTC.js is released under the MIT License. The page does not mention commercial pricing, cloud service plans, or enterprise support. As such, it is better understood as a freely integrable frontend open-source library rather than a hosted SaaS tool.
Its advantages are that it is open source and free, has broad feature coverage, offers straightforward APIs, and supports flexible integration methods. It is suitable for scenarios such as online education, meeting recording, camera capture, screen recording, and exporting Canvas animations. Its drawbacks are that its underlying capabilities depend on browser MediaRecorder/WebRTC and codec implementations, so behavior may vary across browsers; some APIs are marked as deprecated; and information about commercial support and SLA is limited.
The page does not provide information about access from mainland China, network acceleration, or payment-related matters, so china_access can only be rated as unknown. If a project has high stability requirements, it is worth evaluating the browser-native MediaRecorder API or other WebRTC recording libraries as alternatives.
