Android MediaPlayer Error/Info Code

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）

2. MediaError.h

enum {
    MEDIA_ERROR_BASE        = -1000,

    // Not technically an error.
    INFO_FORMAT_CHANGED    = MEDIA_ERROR_BASE - 12,
    INFO_DISCONTINUITY     = MEDIA_ERROR_BASE - 13,
    INFO_OUTPUT_BUFFERS_CHANGED = MEDIA_ERROR_BASE - 14,

    // The following constant values should be in sync with
    // drm/drm_framework_common.h
    DRM_ERROR_BASE = -2000,

    ERROR_DRM_UNKNOWN                       = DRM_ERROR_BASE,

    ERROR_DRM_DEVICE_REVOKED                = DRM_ERROR_BASE - 9,
    ERROR_DRM_RESOURCE_BUSY                 = DRM_ERROR_BASE - 10,

    ERROR_DRM_VENDOR_MAX                    = DRM_ERROR_BASE - 500,
    ERROR_DRM_VENDOR_MIN                    = DRM_ERROR_BASE - 999,

    // Heartbeat Error Codes
    HEARTBEAT_ERROR_BASE = -3000,
    ERROR_HEARTBEAT_TERMINATE_REQUESTED                     = HEARTBEAT_ERROR_BASE,
};
