We are working on both android and iOS platform. To show video according our need, we have changed the android(JAVA library). With the modification of android library, we can scale streams according our layout changes. But in iOS, we can not modify the library and so we can not scale(fit to screen etc.) as per our need. Is there any way to modify iOS library? Or, can we get source code of the library so that we can modify the library?
I'm not sure how you changed our Android SDK. But if you want to make modification in iOS SDK to scale stream, you may need to customize a view which inherits RTCVideoRender class.
