You want to add pod 'AliyunVideoSDKPro', '6.17.2-41775658' similar to the following to your Podfile:

target 'MyApp' do
  pod 'AliyunVideoSDKPro', '6.17.2-41775658'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try AliyunVideoSDKPro
