Scope:
Doc link: https://api-ref.agora.io/en/video-sdk/android/4.x/API/class_playerstreaminfo.html

Since 4.x, the the duration attribute of MediaStreamInfo is in milliseconds, instead of seconds.
This may affect the implementation logic in case of misuse.

Acceptance criteria: The documentation is corrected.

Additional valuable information:
I have tested to read the attribute and can confirm the value is returned in milliseconds.
