Yes, most real-time audio and video SDKs support recording videos into files during audio and video communication. This feature allows developers to save the ongoing audio and video streams as local files, which can be useful for scenarios like meeting recordings, live streaming archives, or user-generated content storage.
For example, in a video conferencing application, the SDK can record the entire session, including all participants' audio and video, into a single file (e.g., MP4 format). This is often implemented by capturing the encoded streams from the SDK and writing them to a file using a media muxer.
If you're building such a feature in the cloud environment, Tencent Cloud provides services like Media Processing Service (MPS) to handle media recording, transcoding, and storage. MPS can work alongside real-time communication SDKs to efficiently manage recorded files, including format conversion, compression, and secure storage in cloud buckets. Additionally, Tencent Cloud TRTC (Tencent Real-Time Communication) offers built-in recording capabilities for its audio and video SDK, allowing seamless integration of live recording features into your application.
For instance, a developer using TRTC's SDK can enable cloud recording to save meetings or live streams directly to Tencent Cloud storage, reducing the need for managing local file systems.
