问题描述

我如何使用表面观，并在安卓3.1录制视频打开前置摄像头？任何人都可以提供样品code？

How do I open the front camera using surface view, and record video in android 3.1? Can anybody provide sample code?

推荐答案

这应该工作，假设你已经创建的表面：

This should works, assuming you have created the surface:

int cameraType = 1; // front
camera = Camera.open(cameraType);

m_recorder = new MediaRecorder();
m_recorder.setPreviewDisplay(m_BeMeSurface);    
m_recorder.setCamera(camera);
m_recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
m_recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
m_recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
m_recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
m_recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
m_recorder.setMaxDuration((int) MAX_TIME); 
m_recorder.setOnInfoListener(m_BeMeSelf);
m_recorder.setVideoSize(320, 240); 
m_recorder.setVideoFrameRate(15); 
m_recorder.setOutputFile(m_path);

m_recorder.prepare();
m_recorder.start();

请注意，并非所有的摄像头硬件支持前置摄像头，视频录制。在这样的情况下，背面相机使用。调用此API，以找出<一个href="http://developer.android.com/reference/android/hardware/Camera.Parameters.html#getSupportedVideoSizes%28%29"相对=nofollow>视频录制大小都可以做

Note that not all camera hardware support front camera video recording. In such a case, the back camera is used. Call this api to find out which video recording sizes are avaliable
