setCameraExposureFactor abstract method

Future<void> setCameraExposureFactor(double factor)

Sets the exposure factor of the current camera.

When the lighting in the shooting environment is insufficient or too bright, it affects the quality of video capture. To achieve better video effects, you can use this method to adjust the camera's exposure factor. This method is applicable to Android and iOS only. You must call this method after enableVideo. The setting takes effect after the camera is successfully turned on, i.e., after the SDK triggers the onLocalVideoStateChanged callback and the local video state is localVideoStreamStateCapturing (1). It is recommended to call isCameraExposureSupported before using this method to check whether the current camera supports adjusting the exposure factor. When you call this method, it sets the exposure factor for the currently used camera, which is the one specified in setCameraCapturerConfiguration.

• factor Exposure factor of the camera. The default value is 0, which means using the camera's default exposure level. The larger the value, the higher the exposure. When the video image is overexposed, you can reduce the exposure factor; when the image is underexposed and dark details are lost, you can increase the exposure factor. If the specified exposure factor exceeds the supported range of the device, the SDK automatically adjusts it to the supported range. On Android, the range is -20.0, 20.0; on iOS, the range is -8.0, 8.0.

Returns When the method call succeeds, there is no return value; when fails, the AgoraRtcException exception is thrown. You need to catch the exception and handle it accordingly. See Error Codes for details and resolution suggestions.
