Video to Audio Conversion

When users want to switch from a video call to an audio call, they can invoke the changeMediaType method of RCCallEngine. Currently, only one-way conversion from video to audio is supported, meaning the parameter can only be RCCallMediaType.audio.

Sample code:

engine?.changeMediaType(RCCallMediaType.audio);
