官方Android 使用Camera2示例项目地址：https://github.com/android/camera-samples
视频录像示例：https://github.com/android/camera-samples/tree/master/Camera2VideoJava
官方Camera2VideoFragment.java停止录像代码，原来代码：会导致APP崩溃
private void stopRecordingVideo() { // UI mIsRecordingVideo = false; mButtonVideo.setText(R.string.record); // Stop recording mMediaRecorder.stop(); mMediaRecorder.reset(); Activity activity = getActivity(); if (null != activity) { Toast.makeText(activity, "Video saved: " + mNextVideoAbsolutePath, Toast.LENGTH_SHORT).show(); Log.d(TAG, "Video saved: " + mNextVideoAbsolutePath); } mNextVideoAbsolutePath = null; startPreview(); }
解决方法如下：
private void stopRecordingVideo() { // UI mIsRecordingVideo = false; mButtonVideo.setText(R.string.record); //必须将这一句放置到MediaRecorder停止释放的前面， //否则就会造成，接收数据方（Encoder）已经停止了，而发送数据的session还在运行。才会造成以上错误。 startPreview(); // Stop recording mMediaRecorder.stop(); mMediaRecorder.reset(); Activity activity = getActivity(); if (null != activity) { Toast.makeText(activity, "Video saved: " + mNextVideoAbsolutePath, Toast.LENGTH_SHORT).show(); Log.d(TAG, "Video saved: " + mNextVideoAbsolutePath); } mNextVideoAbsolutePath = null; }
另外修改closePreviewSession()方法，增加红色字体代码：
private void closePreviewSession() { if (mPreviewSession != null) { try { mPreviewSession.stopRepeating(); mPreviewSession.abortCaptures(); } catch (CameraAccessException e) { e.printStackTrace(); } mPreviewSession.close(); mPreviewSession = null; } }
