抱歉，该视频无法在视频视图中播放？

freinds,

我正在使用以下代码在我的应用程序中显示 mp4 视频 并面临以下问题

我在 google 和 stackoverflow 上看到了很多与这个问题相关的帖子，但每个人都给出了自己的建议，并且没有共同的答案。

1）我在模拟器中看不到视频 2）在不同的手机上，有时很少会播放视频，并且大多数时候都会给出上述消息。

my code

VideoView myVideoView = (VideoView)findViewById(R.id.videoview);

      String viewSource ="http://dev.hpac.dev-site.org/sites/default/files/videos/about/mobile.mp4";

      myVideoView.setVideoURI(Uri.parse(viewSource));
      myVideoView.setMediaController(new MediaController(this));
      myVideoView.requestFocus();
      myVideoView.start();

任何人都可以指导我解决这个问题的方法是什么 任何帮助，将不胜感激。

您可以使用文件创建输出流并获取流的绝对路径，然后将路径放入视频视图

    private String getDataSource(String path) throws IOException {
    if (!URLUtil.isNetworkUrl(path)) {
        return path;
    } else {
        URL url = new URL(path);
        URLConnection cn = url.openConnection();
        cn.connect();
        InputStream stream = cn.getInputStream();
        if (stream == null)
            throw new RuntimeException("stream is null");
        File temp = File.createTempFile("mediaplayertmp", "dat");
        temp.deleteOnExit();
        String tempPath = temp.getAbsolutePath();
        @SuppressWarnings("resource")
        FileOutputStream out = new FileOutputStream(temp);
        byte buf[] = new byte[128];
        do {
            int numread = stream.read(buf);
            if (numread <= 0)
                break;
            out.write(buf, 0, numread);
        } while (true);
        try {
            stream.close();
        } catch (IOException ex) {
            Log.e(TAG, "error: " + ex.getMessage(), ex);
        }
        return tempPath;
    }
}

and

public void initVideo() {
    try {

        if (!mVideoView.isPlaying()) {

            if (url > playList.size() - 1) {
                url = 0;
            }
            String[] playurl = (playList.get(url)).split("\\.");
            String urlExtention = playurl[playurl.length - 1];

            if (urlExtention.equals("mp4")) {
                playVideo(playList.get(url));
            } else if (urlExtention.equals("jpg")
                    || urlExtention.equals("jpeg")) {

                Intent intentShedule = new Intent(Default_Player.this,
                        ImagePlayer.class);

                intentShedule.putExtra("imagePath", playList.get(url));
                intentShedule.putExtra("urlValue", url);
                intentShedule.putExtra("playlistType", playlistType);
                intentShedule.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                startActivity(intentShedule);
                finish();
            } else {
                Intent intentShedule = new Intent(Default_Player.this,
                        WebContentView.class);

                intentShedule.putExtra("webPath", playList.get(url));
                intentShedule.putExtra("urlValue", url);
                intentShedule.putExtra("playlistType", playlistType);
                intentShedule.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                startActivity(intentShedule);
                finish();
            }

        }

        mVideoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {

            @Override
            public boolean onError(MediaPlayer mp, int what, int extra) {
                System.out.println("set on error listner");

                //do somthing if alert this video can not be played

                return false;
            }
        });

        mVideoView
                .setOnCompletionListener(new MediaPlayer.OnCompletionListener() {

                    public void onCompletion(MediaPlayer vmp) {

                        playnew();
                    }
                });

    } catch (Exception e) {

    }

    // TODO Auto-generated method stub

}

如果警告该视频无法播放，则在错误侦听器上使用
