Web-based content recording and adaptive streaming
Systems and methods for recording “on-screen” content of a user device via a web browser-based coupling with a content recording system. The content to be recorded may include an audio component and a video component. The audio and video components are merged into a single stream that contains the content displayed via the user device. Segments of the recorded stream are periodically stored to a local storage associated with the web browser. Upon completion of the storage of a segment in the local storage, the segment is uploaded to the content recording system. As the recording session persists, multiple file segments are created in the local storage of the web browser and uploaded, on a segment-by-segment basis, to the server. The server of the content recording system concatenates the multiple uploaded file segments to generate a single file associated with the recorded session.
