Question

有没有办法在使用 myCamera.getParameters().setColorEffect(Camera.Parameters.EFFECT_NEGATIVE); 的前置摄像头的视频录制中应用摄像头的默认颜色效果？负面影响和其他影响

Answer 1

您必须在CaptureRequest.Builder 中设置参数，在那里您可以应用您想要的所有效果：

int colorEffectValue = 
//Choose your effect:
//CaptureRequest.CONTROL_EFFECT_MODE_MONO
//CaptureRequest.CONTROL_EFFECT_MODE_NEGATIVE
//CaptureRequest.CONTROL_EFFECT_MODE_SOLARIZE
//CaptureRequest.CONTROL_EFFECT_MODE_SEPIA
//CaptureRequest.CONTROL_EFFECT_MODE_POSTERIZE
//CaptureRequest.CONTROL_EFFECT_MODE_WHITEBOARD
//CaptureRequest.CONTROL_EFFECT_MODE_BLACKBOARD
//etc, you can find all modes in CameraMetadata
youtCaptureBuilder.set(CaptureRequest.CONTROL_EFFECT_MODE, colorEffectValue);
