Htc 设备因使用 MediaRecorder 录制设备屏幕而崩溃。
当我停止在设备的主屏幕上录制时，我没有问题。但是，当我停止在任何应用程序屏幕上录制时，surfaceflinger 库会崩溃。
这里是设置记录器的代码：
mMediaRecorder = new MediaRecorder();
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
mMediaRecorder.setVideoEncodingBitRate(700 * 1000);
mMediaRecorder.setVideoFrameRate(30);
mMediaRecorder.setVideoSize(recordDisplayWidth, recordDisplayHeight);
mMediaRecorder.prepare();
mMediaProjection.createVirtualDisplay(mFragment.getActivity().getLocalClassName(),
recordDisplayWidth, recordDisplayHeight, mScreenDensity,
DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR, mMediaRecorder.getSurface(), null, null)
mMediaRecorder.start();
录制成功开始，但是当我执行 mMediaRecorder.stop() 时，surfaceflinger 崩溃。这是崩溃的日志：

可以请一些帮助。这不会发生在 HTC 以外的设备上。
