我停止录制时MediaRecorder失败

Question

我有这个错误.有人可以帮助我,我认为这是关于触摸听众的事情......当我松开手指时会发生错误.

当我尝试运行此代码时会发生这种情况:

来自触摸听众:

/// Preview is SurfaceView in my view
preview.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:

                prepareRecording();
                break;
            case MotionEvent.ACTION_MOVE:
            //Log.d(TAG, String.format("ACTION_MOVE | x:%s y:%s", 
                break;
            case MotionEvent.ACTION_UP:
                stopRecording();
                break;
            }
            return true;
        }
    });

而这两种方法:

private void prepareRecording() {
    try {
        camera.unlock();

        recorder = new MediaRecorder();
        recorder.setCamera(camera);
        recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
        recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);

        File tempFile = new File(Environment.getExternalStorageDirectory(), "/rec/temp/video_" + String.valueOf(videoCount) + ".mp4");

        recorder.setOutputFile(tempFile.getPath());
        recorder.setVideoFrameRate(25);
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
        recorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
        recorder.setPreviewDisplay(holder.getSurface());

        recorder.prepare();
        recorder.start();
    }  catch (IllegalStateException e) {
        Log.e("REDORDING :: ",e.getMessage());
        e.printStackTrace();
    } catch (IOException e) {
        Log.e("REDORDING :: ",e.getMessage());
        e.printStackTrace();
    }
}

private void stopRecording() {
    recorder.stop();
    camera.lock();
}

Answer 1

看看文档:

请注意,如果在调用stop()时未收到有效的音频/视频数据,则会故意将RuntimeException抛出到应用程序.如果在start()之后立即调用stop(),则会发生这种情况.失败让应用程序相应地采取操作来清理输出文件(例如删除输出文件),因为在发生这种情况时输出文件没有正确构造.

换句话说:Dalvik故意抛出异常.您必须在应用程序之后处理它以进行清理.你必须像这样处理它:

private void stopRecording() {
    try{
        recorder.stop();
    }catch(RuntimeException stopException){
        //handle cleanup here
    }
    camera.lock();
}

Answer 2

当我使用录制音频时AMR_WB，我遇到了类似的错误-1007 ，但事实证明，问题是我忘记了设置采样率。

mediaRecorder.setAudioSamplingRate(16000);
