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
file /storage/emulated/0/Android/data/com.gold.cameratwoapi/files/video.mp4
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();
}
