    Architecture

    The server of ApsaraVideo Live can collect, process, and distribute live streams in real time.Live streaming process

    1. A streamer uses a stream ingest SDK to ingest a live stream that is collected by a video capture device. ApsaraVideo Live uses edge ingest to distribute the live stream to Alibaba Cloud points-of-presence (CDN POPs), which then accelerate the delivery of the live stream to live centers of ApsaraVideo Live.

    2. After the live stream is delivered to live centers of ApsaraVideo Live, you can process the stream based on your business requirements. For example, you can transcode the stream, perform time shifting on the stream, record the stream, or capture snapshots of the stream.

    3. The processed stream is also distributed to CDN POPs, which then accelerate the delivery of the processed stream to viewers' devices for playback. You can integrate ApsaraVideo Player SDK into your mobile application that is used by viewers to play the stream.

    4. You can also use the Live-to-VOD feature to store the recorded stream as an on-demand video in ApsaraVideo VOD. In ApsaraVideo VOD, you can edit and play the video. This way, you can produce short videos by using live streams and communicate the short videos to your target audience in a convenient manner.
