Android VideoView不会播放MKV文件

我的VideoViewer不会播放任何MKV文件。我已经测试过.3gp视频文件，它们工作正常，但MKV文件不起作用。视频永远不会显示，无缓冲或任何内容。屏幕会显示正常，但正如我所说，视频播放器是不可见的或不在那里，我不知道。在输出中，它会说沿着线的东西：Android VideoView不会播放MKV文件

connect to ........ 
new range: ........

又一遍地重复这些取决于MKV有多大。然后它会使应用程序停止响应或提供以下输出。

的输出是：

MKV不是Android的下supported media容器。

支持的视频文件类型（容器格式）为：.3gp使用，和的.mp4 .webm。对支持的视频编解码器也有限制。

此外，视频编解码器的格式（H263，H264，MPEG-4，VP8）和容器格式（3GP，MP4，WEBM）是两个不同的事情。这意味着，即使你有.mp4文件，也不意味着Android能够播放它。它的内容还需要使用受支持的编解码器进行编码。

我以为MKV可以通过安装编解码器来播放？我知道linux内核支持它。 – 2011-09-25 20:23:39

MKV是一种不是编解码器的容器格式。 –

呃，媒体播放器应用程序如何播放MKV文件呢？我不太明白。 – Fritz

由于Android 4.0以上版本，如所描述here MKV视频支持。但正如@Peter Knego所说，视频编解码器格式和容器格式是两回事。

Android的媒体API似乎是不良记录（或者至少是在质询时间），其他人已经指出here。然而，使用技巧从this post和this answer我能够从两个样本的视频检索两个信息：

Uri videoUri = Uri.parse("android.resource://" 
      + getPackageName() + "/" + R.raw.sample_video); 
// Codec Format 
extractor = new MediaExtractor(); 
extractor.setDataSource(this, videoUri, null); 

for (int i = 0; i < extractor.getTrackCount(); i++) { 
    MediaFormat format = extractor.getTrackFormat(i); 
    String mime = format.getString(MediaFormat.KEY_MIME); 
    if (mime.startsWith("video/")) { 
     Log.d(TAG, "CODEC: " + mime); 
     break; 
    } 
} 
// Container Format 
MediaMetadataRetriever mmr = new MediaMetadataRetriever(); 
mmr.setDataSource(this, videoUri); 

Log.d(TAG, "CONTAINER: " 
     + mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_MIMETYPE));

从两个不同的MKV视频，我得到了以下成果：

D/VideoActivity: CODEC: video/mp4v-es 
D/VideoActivity: CONTAINER: video/x-matroska 

D/VideoActivity: CODEC: video/avc 
D/VideoActivity: CONTAINER: video/x-matroska

虽然我认为处理不支持的文件的最佳方法可能是使用try/catch块和/或VideoView.setOnErrorListening（doc & example），有人可以使用上述方法在播放媒体之前提取更多的媒体细节，或者至少记录发生错误时发生的情况。
