Both streaming and playing operations are performed at the PC end. For streaming opeartion at the mobile end, refer to Android streaming and iOS streaming. For playing at the mobile end, refer to Android playing and iOS playing.

Step 1: Preparation


  • Your domain name has completed the website record-filing.

  • To begin a live activity, you need streaming tools to upload the live video, and playing tools to pull the live video.

    1. Select a region, and click Add New Domain.


    2. Enter the Live domain name, and click Next step.



    • We recommend the domain name for live video completes ICP record filing before it is readied for use. See Record filing process for details.

    • When configured successfully, the domain name automatically completes the configuration of CDN live acceleration. The live acceleration is available after the domain name complete the CNAME binding.

  3. Bind CNAME.

    Modify the DNS and CNAME record of the live video domain name you added to the CNAME address displayed on the live video domain name management details page. Then, bind the streaming address that Alibaba Cloud provides with the live video domain name, so that the stream is pushed to the live video center at the same time it is pushed to the live video domain name. To bind the CNAME address of the domain name, follow these steps.

          • If it is a newly created domain name, the resolution will not involve DNS refreshing.
          • If the CNAME is changed, different data is cached on different DNSs. If this occurs, it may take up to 48 hours to complete the updates.
    • Alternative domain name application method

      • If the domain name is applied for using another method, you must perform CNAME binding at the website at which the domain name is added.
