【问题描述】：

我正在尝试从相机录制视频，一切正常，但在 Samsung SM-C7010 中显示错误消息 start failed。

这是我正在使用的。

    mMediaRecorder = new MediaRecorder();

    // Step 1: Unlock and set camera to MediaRecorder
    mCamera.unlock();
    mMediaRecorder.setCamera(mCamera);

    // Step 2: Set sources
    mMediaRecorder.setAudiosource(MediaRecorder.AudioSource.CAMCORDER);
    mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

    // Step 3: Set a CamcorderProfile (requires API Level 8 or higher)
    /*CamcorderProfile profile = CamcorderProfile.get(CamcorderProfile.QUALITY_TIME_LAPSE_720P);
    mMediaRecorder.setCaptureRate(profile.videoFrameRate/6.0f);
    mMediaRecorder.setVideoEncodingBitRate(profile.videoBitRate);
    mMediaRecorder.setProfile(profile);*/
    CamcorderProfile profile = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
    mMediaRecorder.setProfile(profile);

    // Step 4: Set output file
    mMediaRecorder.setOutputFile(String.valueOf(camMediaFile));
    mMediaRecorder.setMaxDuration(5000);
    mMediaRecorder.setCaptureRate(profile.videoFrameRate/6.0f);
    mMediaRecorder.setVideoFrameRate(10);

    mMediaRecorder.setOrientationHint(videoOrientation);

   // Step 5: Set the preview output
    mMediaRecorder.setPreviewDisplay(this.getHolder().getSurface());


    // Step 6: Prepare configured MediaRecorder

    mMediaRecorder.prepare();
    mMediaRecorder.start();

删除这两行后一切正常

   mMediaRecorder.setCaptureRate(profile.videoFrameRate/6.0f);
   mMediaRecorder.setVideoFrameRate(10);

我认为问题出在这两行，但不知道问题出在哪里。

【问题讨论】：

请添加完整的错误日志

请检查更新

***.com/questions/2859458/…

我在那里检查的内容。这与这个问题完全不同，我已经正确设置了所有内容。唯一的问题在于特定的移动型号。我还提到了问题所在的行，但不知道确切的问题以及如何解决

【参考方案1】：

试试这个

  mediaRecorder.setCaptureRate(20);
  mediaRecorder.setVideoFrameRate(20);

【讨论】：

为什么你都设置了 20 的值？
