Android MediaPlayer Error/Info Code

標籤：

1. 常見錯誤error(-38, 0)

我覺得-38表示在當前的MediaPlayer狀態下,不能運行你的操作。

詳細怎樣做請參考：Android MediaPlayer

另外我在其它資料中。發現有人覺得-38定義在:pvmf_return_codes.h檔案裡：

-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: 事實上代表MEDIA_ERROR_UNKNOWN
-2147483648: （0x80000000）沒有做什麼說明，實際上它也是代表unknown error

這中錯誤大多是在播放MP4的時候出現，主要原因是由於當前的機器不支援這樣的視頻編碼（H263。H264，MPEG-3等，不是視頻容器格式）

2. MediaError.h

3. MediaPlayer

public static final int MEDIA_ERROR_IO Added in API level 17 File or network related operation errors. Constant Value: -1004 (0xfffffc14) public static final int MEDIA_ERROR_MALFORMED Added in API level 17 Bitstream is not conforming to the related coding standard or file spec. Constant Value: -1007 (0xfffffc11) public static final int MEDIA_ERROR_NOT_VALID_FOR_PROGRESSIVE_PLAYBACK Added in API level 3 The video is streamed and its container is not valid for progressive playback i.e the video's index (e.g moov atom) is not at the start of the file.See AlsoMediaPlayer.OnErrorListener Constant Value: 200 (0x000000c8) public static final int MEDIA_ERROR_SERVER_DIED Added in API level 1 Media server died. In this case, the application must release the MediaPlayer object and instantiate a new one.See AlsoMediaPlayer.OnErrorListener Constant Value: 100 (0x00000064) public static final int MEDIA_ERROR_TIMED_OUT Added in API level 17 Some operation takes too long to complete, usually more than 3-5 seconds. Constant Value: -110 (0xffffff92) public static final int MEDIA_ERROR_UNKNOWN Added in API level 1 Unspecified media player error.See AlsoMediaPlayer.OnErrorListener Constant Value: 1 (0x00000001) public static final int MEDIA_ERROR_UNSUPPORTED Added in API level 17 Bitstream is conforming to the related coding standard or file spec, but the media framework does not support the feature. Constant Value: -1010 (0xfffffc0e) public static final int MEDIA_INFO_BAD_INTERLEAVING Added in API level 3 Bad interleaving means that a media has been improperly interleaved or not interleaved at all, e.g has all the video samples first then all the audio ones. Video is playing but a lot of disk seeks may be happening.See AlsoMediaPlayer.OnInfoListener Constant Value: 800 (0x00000320) public static final int MEDIA_INFO_BUFFERING_END Added in API level 9 MediaPlayer is resuming playback after filling buffers.See AlsoMediaPlayer.OnInfoListener Constant Value: 702 (0x000002be) public static final int MEDIA_INFO_BUFFERING_START Added in API level 9 MediaPlayer is temporarily pausing playback internally in order to buffer more data.See AlsoMediaPlayer.OnInfoListener Constant Value: 701 (0x000002bd) public static final int MEDIA_INFO_METADATA_UPDATE Added in API level 5 A new set of metadata is available.See AlsoMediaPlayer.OnInfoListener Constant Value: 802 (0x00000322) public static final int MEDIA_INFO_NOT_SEEKABLE Added in API level 3 The media cannot be seeked (e.g live stream)See AlsoMediaPlayer.OnInfoListener Constant Value: 801 (0x00000321) public static final int MEDIA_INFO_UNKNOWN Added in API level 3 Unspecified media player info.See AlsoMediaPlayer.OnInfoListener Constant Value: 1 (0x00000001) public static final int MEDIA_INFO_VIDEO_RENDERING_START Added in API level 17 The player just pushed the very first video frame for rendering.See AlsoMediaPlayer.OnInfoListener Constant Value: 3 (0x00000003) public static final int MEDIA_INFO_VIDEO_TRACK_LAGGING Added in API level 3 The video is too complex for the decoder: it can't decode frames fast enough. Possibly only the audio plays fine at this stage.See AlsoMediaPlayer.OnInfoListener Constant Value: 700 (0x000002bc)
