java – 如何在不停止mediarecorder的情况下更改mediarecorder的

>停止录音机
>重设录像机状态
>检索由记录器写入的文件,并以不同的线程上传(多部分表单数据).
>根据当前时间戳的散列将录像机的文件更改为新文件.
>每30秒重复一次

这样做适合我的需要,因为每个30秒的视频文件大小不超过1MB,上传顺利进行.

但是我所面临的问题是,每当媒体记录器停止并再次启动时,延迟时间约为500ms,所以在服务器上收到的视频每隔30秒就会发生,这对我目前的情况来说是非常糟糕的,所以我正在考虑是否可以在飞行中更改录音机正在写的文件？

相关代码：

GenericCallback onTickListener = new GenericCallback() {
        @Override
        public void execute(Object data) {
            int timeElapsedInSecs = (int) data;
            if (timeElapsedInSecs % pingIntervalInSecs == 0) {
                new API(getActivity().getApplicationContext()).pingServer(objInterviewQuestion.getCurrentAccessToken(),new NetworkCallback() {
                    @Override
                    public void execute(int response_code,Object result) {
                        // TODO: HANDLE callback
                    }
                });
            }
            if (timeElapsedInSecs % uploadIntervalInSecs == 0 && timeElapsedInSecs < maxTimeInSeconds) {
                if (timeElapsedInSecs / uploadIntervalInSecs >= 1) {
                    if(stopAndResetRecorder()) {
                        openConnectionToUploadQueue();
                        uploadQueue.add(
                                new InterviewAnswer(0,objInterviewQuestion.getQid(),objInterviewQuestion.getAvf(),objInterviewQuestion.getNext(),objInterviewQuestion.getCurrentAccessToken()));
                        objInterviewQuestion.setAvf(MiscHelpers.getOutputMediaFilePath());
                        initializeAndStartRecording();
                    }
                }
            }
        }
    };

这里是initializeAndStartRecording()：

private boolean initializeAndStartRecording() {
        Log.i("INFO","initializeAndStartRecording");
        if (mCamera != null) {
            try {

                mMediaRecorder = CameraHelpers.initializeRecorder(mCamera,mCameraPreview,desiredVideoWidth,desiredVideoHeight);

                mMediaRecorder.setOutputFile(objInterviewQuestion.getAvf());
                mMediaRecorder.prepare();
                mMediaRecorder.start();
                img_recording.setVisibility(View.VISIBLE);

                is_recording = true;
                return true;
            } catch (Exception ex) {
                MiscHelpers.showMsg(getActivity(),getString(R.string.err_cannot_start_recorder),AppMsg.STYLE_ALERT);
                return false;
            }


        } else {
            MiscHelpers.showMsg(getActivity(),getString(R.string.err_camera_not_available),AppMsg.STYLE_ALERT);
            return false;
        }
    }

这里是stopAndResetRecorder：

boolean stopAndResetRecorder() {
        boolean success = false;
        try {
            if (mMediaRecorder != null) {
                try {
                    //stop recording
                    mMediaRecorder.stop();
                    mMediaRecorder.reset();
                    mMediaRecorder.release();
                    mMediaRecorder = null;
                    Log.d("MediaRecorder","Recorder Stopped");
                    success = true;
                } catch (Exception ex) {
                    if(ex != null && ex.getMessage()!=null && ex.getMessage().isEmpty()){
                        Crashlytics.log(Log.ERROR,"Failed to stop MediaRecorder",ex.getMessage());
                        Crashlytics.logException(ex);
                    }
                    success = false;
                } finally {
                    mMediaRecorder = null;
                    is_recording = false;
                    is_recording = false;
                }
            }
        } catch (Exception ex) {
            success = false;
        }
        Log.d("MediaRecorder","Success = " + String.valueOf(success));
        return success;
    }
