Android相机2 Api

我一直在尝试camera2 API.我已经下载了代码

https://developer.android.com/samples/Camera2Video/index.html了解它是如何工作的.它工作正常,直到我停止录音.当我停止录制时,运行以下代码.

private void stopRecordingVideo() {
        // UI
        mIsRecordingVideo = false;
        mBtn_Video.setText(R.string.record);
        // Stop recording
        try {
            mMediaRecorder.stop();
            mMediaRecorder.reset();
        }
        catch (Exception e) {
            e.printstacktrace();
        }
        Activity activity = getActivity();
        if (null != activity) {
            System.out.println("file " +  getVideoFile(activity));
            Toast.makeText(activity,"Video saved: " + getVideoFile(activity),Toast.LENGTH_SHORT).show();
        }
        startPreview();

在mMediaRecorder.stop();它会抛出以下错误

01-12 16:24:23.115    2161-2200/com.cameratwoapi E/Surface﹕ queueBuffer: error queuing buffer to SurfaceTexture,-19

任何想法我做错了什么我花了几个小时,但找不到任何解决方案.

编辑 – 我正在使用geneymotion模拟器.我正在使用的路径

谢谢

解决方法

我的解决办法是改变void stopRecordingVideo()如下：

private void stopRecordingVideo() {
// UI
mIsRecordingVideo = false;
mButtonVideo.setText(R.string.record);
// Added by Ben Ning,to resolve exception issue when stop recording.
try {
    mPreviewSession.stopRepeating();
    mPreviewSession.abortCaptures();
} catch (CameraAccessException e) {
    e.printstacktrace();
} 

// Stop recording
mMediaRecorder.stop();
mMediaRecorder.reset();

}

关键是：

try {
    mPreviewSession.stopRepeating();
    mPreviewSession.abortCaptures();
} catch (CameraAccessException e) {
    e.printstacktrace();
}
