Question

我正在尝试从相机录制视频，但一切正常，但是在 Samsung SM-C7010 中，它显示错误消息启动失败。

这就是我正在使用的。

    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();

当我删除这两行时，一切都很好

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

我认为问题出在这两行，但不知道是什么问题。

Answer 1

尝试一下

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

录制视频时出现RuntimeException [特定于设备]
