Android MediaRecoder.stop（）花费的时间太长

当我使用MediaRecorder录制完视频后，函数stop（）花费了我太长的时间来关闭文件流，我的代码怎么了

我已尝试重置MediaRecorder的所有配置，并检查了框架代码，本机函数stop也需要很长时间，但当我使用其他摄像头（如“OpenCamera”）时，停止录制需要很短的时间。同时我检查了项目“OpenCamera”代码，并复制了MediaRecorder的配置，它对我不起作用

这是我关于开始和停止的代码

public void startRecord(String path) {
        if (currentState.compareTo(State.previewing) == 0) {
            this.mediaPath = path;
            currentState = State.recording;
            mediaRecorder = new MediaRecorder();
            mCamera.unlock();

            mediaRecorder.setCamera(mCamera);
            mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
            mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
            mediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_LOW));
            mediaRecorder.setVideoSize(videoSize.width, videoSize.height);
            mediaRecorder.setOrientationHint(videoRotation);

            mediaRecorder.setOutputFile(path);
            File file = new File(Environment.getExternalStorageDirectory().getAbsoluteFile() + "/DCIM/Camera");
            if (!file.exists()) {
                file.mkdirs();
            }
            try {
                mediaRecorder.prepare();
                mediaRecorder.start();
                audioManager.requestAudioFocus(audioChangeListener, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);
            } catch (Exception e) {
                LogTool.e(this, "error !!!", e);
                mCamera.lock();
                clearException(path);
                if (cameraCallback != null) {
                    cameraCallback.onRecordError();
                }
            }
        }
    }

    public void stopRecord(boolean force) {
        if (currentState.compareTo(State.recording) == 0) {
            audioManager.abandonAudioFocus(audioChangeListener);
            currentState = force ? State.previewing : State.showing;

            if (mediaRecorder != null) {
                try {
                    mediaRecorder.stop();
                    mediaRecorder.reset();
                    mediaRecorder.release();
                    mediaRecorder = null;
                } catch (Exception e) {
                    clearException(mediaPath);
                    if (!force) {
                        Toast.makeText(mContext, mContext.getResources().getString(R.string.video_tool_short),
                                Toast.LENGTH_SHORT).show();
                    }
                    if (cameraCallback != null) {
                        cameraCallback.onRecordError();
                    }
                    return;
                }

                if (force) {
                    File errorFile = new File(mediaPath);
                    if (errorFile.exists()) {
                        errorFile.delete();
                    }
                    if (cameraCallback != null) {
                        cameraCallback.onRecordError();
                    }
                } else {
                    if (cameraCallback != null) {
                        cameraCallback.onMediaSaved(mediaPath);
                    }
                }
            }
        }
    }

关于框架的日志显示在那里：

01-01 13:32:08.650 4129-4129/? D/MediaRecorder: start begin
01-01 13:32:09.150 4129-4129/? D/MediaRecorder: start end
01-01 13:32:12.620 4129-4129/? D/MediaRecorder: stop start
01-01 13:32:17.770 4129-4129/? D/MediaRecorder: stop end

您可以看到系统日志显示停止该操作需要5秒。

可能是设备错误。当我设置setRecordingHint（true）时，它为我解决了这个问题
