setVideoSettings method

Future<void> setVideoSettings({ int? bitrate, int? width, int? height, int? frameInterval, String? profileLevel, double? expectedFrameRate, String? bitRateMode, })

set video Settings

expectedFrameRate：HaishinKit 2.2.2+，写入编码期望帧率并进入 RTMP onMetaData 的 framerate。

bitRateMode：average（默认）、constant（iOS 16+）、variable（iOS 26+，对应 VideoToolbox VBR）。 Only supports ios
