1. 常见错误

error(-38, 0)

我觉得-38表示在当前的MediaPlayer状态下,不能运行你的操作。

详细怎样做请參考：Android MediaPlayer

另外我在其它资料中。发现有人觉得-38定义在:pvmf_return_codes.h文件里：

-38: DRM clock is not available or cannot be read

0: Return code for pending completion

  /*

   * DRM clock is not available or cannot be read

   */

   const PVMFStatus PVMFErrDrmClockError = (-38);

  /*

   * Return code for pending completion

   */

   const PVMFStatus PVMFPending = 0;

error (1, -2147483648)

1: 事实上代表MEDIA_ERROR_UNKNOWN

-2147483648: （0x80000000）没有做什么说明，实际上它也是代表unknown error

这中错误大多是在播放MP4的时候出现，主要原因是由于当前的机器不支持这样的视频编码（H263。H264，MPEG-3等，不是视频容器格式）
