Android Camera 2 Api [英] Android Camera 2 Api

问题描述

我一直在尝试使用camera2 API.我已经从

I have been trying camera2 API. I have downloaded code from

https://developer.android.com/samples/Camera2Video/index.html 进行学习关于它是如何工作的.直到我停止录制为止，它都可以正常工作.当我停止记录时，它将运行以下代码.

https://developer.android.com/samples/Camera2Video/index.html to learn about how it works. It works fine till I stop recording. When I stop recording it runs following code.

 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();

位于mMediaRecorder.stop();它会引发以下错误

at mMediaRecorder.stop(); it throw following error

任何想法我在做什么错.我花了几个小时，但找不到任何解决方案.

Any Idea what I am doing wrong. I spent few hours but couldn't find any solution.

编辑-我正在使用geneymotion模拟器.我正在使用的路径

Edit - I am using geneymotion emulator. The path I am using

推荐答案

我的解决方案是按以下方式更改void stopRecordingVideo():

My solution is to change void stopRecordingVideo() as following:

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();
}
