Android MediaPlayer 错误无法播放此视频

Question

我正在开发用于视频录制的自定义相机应用程序。录制的视频存储在 SD 卡上。该代码适用于所有设备，但 T-Mobile S3 (SGH-T999 android v 4.1.2) 除外，在该设备上出现“无法播放此视频”错误。我对这个问题进行了很多研究，也尝试过更改参数但仍然无法解决。

代码 fragment 。

CamcorderProfile camcorderProfile=CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);

    mMediaRecorder.setVideoEncoder(VideoEncoder.MPEG_4_SP);
    mMediaRecorder.setVideoSize(width, ht);

提前致谢。

请注意您的测试设备的规范。您可以使用 raw 和 mp4 作为常用选项
