read / write

Field description: whether resolution adjustment is allowed

Recommended value - For mobile live streaming, `false` is recommended. - For video call, if smoothness is of higher priority, `true` is recommended. In this case, if the network bandwidth is limited, the SDK will automatically reduce the resolution to ensure better smoothness (only valid for `TRTCVideoStreamTypeBig`). - Default value: false.

Note: when recording is needed, if `true` is selected, please make sure that the resolution adjustment will not affect the recording effect during the call.

## Implementation
