CameraCaptureOutputPreference enum Null safety

设置摄像头采集偏好。

Constants

Auto → const CameraCaptureOutputPreference

（默认）自动调整采集参数。SDK 根据实际的采集设备性能及网络情况，选择合适的摄像头输出参数，从而保证设备性能。在这种情况下，预览质量接近于编码器的输出质量。

@JsonValue(0)
const CameraCaptureOutputPreference(0)
Manual → const CameraCaptureOutputPreference

允许你设置本地摄像头采集的视频宽高。

@JsonValue(3)
const CameraCaptureOutputPreference(3)
Performance → const CameraCaptureOutputPreference

优先保证设备性能。SDK 根据你在 setVideoEncoderConfiguration 中设置编码器的分辨率和帧率，选择最接近的摄像头输出参数，从而保证设备性能。在这种情况下，预览质量接近于编码器的输出质量。 详见 RtcEngine.setVideoEncoderConfiguration。

@JsonValue(1)
const CameraCaptureOutputPreference(1)
Preview → const CameraCaptureOutputPreference

优先保证视频预览质量。SDK选择较高的摄像头输出参数，从而提高预览视频的质量。在这种情况下，会消耗更多的 CPU 及内存做视频前处理。
