Architecture

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

  1. A streamer collects live content with a video capture device and pushes the live stream using the Push SDK. The live stream is initially pushed to the Alibaba Cloud CDN point of presence (POP) nearest to the streamer. Then, ApsaraVideo Live uses edge ingest to ingest the live stream from POP to its live center. This enhances the speed and stability of data transfer from the streamer to the live center.

  2. After the live stream is pushed to the live center, you can process the stream based on your business requirements. For example, you can transcode the stream, configure time shifting, record the live content, or capture snapshots.

  3. The processed stream is distributed to CDN POPs, which then deliver the stream to viewers' devices for playback. You can integrate ApsaraVideo Player SDK into your mobile app used by viewers to play the stream.

  4. You can also use the Live-to-VOD feature to store the recorded stream as a video-on-demand asset in ApsaraVideo VOD. Then, you can edit the recorded live content to produce short videos and deliver the VOD content to your target audience in a convenient manner.
