This topic describes how to obtain a license of Queen SDK. You are charged for Queen SDK based on the license that you use. Licenses for different editions have different prices and provide different features.

All-in-one licenses

  • Queen SDK V2.0.0 and later support all-in-one licenses. You can use an all-in-one license to authorize all applications within the same Alibaba Cloud account to access video cloud SDKs. After you send an email to to request a free trial license or request a license, Alibaba Cloud replies to your email with a LicenseKey and LicenseFile. For more information, see Request a free trial license or Request a license. You must integrate the LicenseKey and LicenseFile into your project. For more information, see Queen SDK Integration.
  • After you use an all-in-one license, if you integrate multiple video cloud SDKs, such as the short video SDK of ApsaraVideo VOD and Queen SDK of ApsaraVideo Live, into the same application, the application uses the same LicenseKey and LicenseFile for both SDKs. If your application has multiple shadow applications, or the Debug package and Release package have different package names, signatures, or bundle IDs, multiple license files exist because each license file is bound to a different package name, signature, and bundle ID.
  • If you upgrade Queen SDK from V1.X.X to V2.0.0 or later, you must send an email to again to request a LicenseKey and LicenseFile, and specify Request License File in the subject of the email. After your email is received, Alibaba Cloud sends you the LicenseKey and LicenseFile within 48 hours on business days.
  • If the features that you purchase are updated or need to be renewed, the license file must also be updated. In this case, you must send an email to to obtain the latest license file and then import the obtained license file into the project. For more information, see Request a license.
