Push Configuration

Last updated: 2021-09-18 16:38:09

    To protect the information security of live streaming, push authentication is enabled for CSS push domain names by default. You can use the push address generator on the push address details page to generate a push URL. Then, you can use the URL to push the stream (upload the live streaming video) to the CSS platform.


    • CSS provides a test domain name xxxx.livepush.myqcloud.com. You can use it for push testing, but we do not recommend using it as the push domain name for your real business.
    • CSS can only generate push URLs in RTMP format.
    • The generated push URL is valid before the set expiration time. You can generate a new URL after the old one expires.

      2. Enter a custom StreamName, such as liveteststream.
      3. Click Generate Push Address to generate an RTMP push URL containing the StreamName.
    3. You can test, disable, or delete a stream in Stream Management after live push.
    4. After the push URL is generated, you can use it to initiate live push. To view live streaming, you should use a playback URL. For more information, please see Playback Configuration.

    Notes on Push URL

    RTMP push URL format:



    • domain: push domain name
    • AppName: live streaming application name, which is live by default and customizable
    • StreamName: custom stream name used to identify a live stream
    • txSecret: authentication string generated after push authentication is enabled
    • txTime: expiration timestamp set for a push URL configured in the console
    • If you have enabled authentication for the domain name, the actual URL expiration time will be txTime plus the key validity period.
