这是一种魔法...... VideoView，并在Android 3.1与4.1的视频显示 [英] It's a kind of magic... VideoView and displaying videos on Android 3.1 vs. 4.1

问题描述

喜的Andr​​oid程序员，

Hi android programmers,

我已经很久挣扎了一整天上似乎有些奇怪，并没有解决的问题。
我追求的是一些指导和一些previous经验。
出于测试目的，我有一个摩托罗拉Xoom Galaxy Nexus的标签 的Galaxy Nexus手机和的Galaxy Tab 10.1

I've been struggling all day long on a problem that seems strange and with no solution. What I seek is some guidance and some previous experiences. For testing purposes I have a Motorola Xoom, Galaxy Nexus Tab, Galaxy Nexus phone, and a Galaxy Tab 10.1.

主要检测应用发达/在的Galaxy Tab 10.1 。
应用程序是很简单的。 pressing一个按钮 - >开始视频

The main testing application is developed for/in the Galaxy Tab 10.1. The application is very simple. Pressing a button -> starting a video.

应用程序运行在的糖豆的设备的罚款。
但在 3.1 设备我虽然没有视频出现只能听到声音。

The application runs fine on the Jelly Beans devices. But on the 3.1 devices I can only hear the audio while no video appears.

要解决我创造了很多不同的codeCS /分辨率网格中的问题，但这似乎没有影响到播放（仍然只有声音没有画面）。

To troubleshoot the issue I created a grid with many different codecs/resolutions, but this seems not to affect the playback (still only audio and no video).

不用说，应用程序运行流畅糖豆手机和平板电脑上。

Needless to say, the application runs smoothly on the Jelly Beans phone and tablet.

有没有人曾与Xoom的或/和Galaxy Tab的10.1以前的经验？

Has anybody had prior experience with the Xoom or/and the Galaxy Tab 10.1?

以防万一，有些人可能会认为有与我的code这里有一个问题是：

Just in case some might think there's a problem with my code here is it:

VideoView v[];
@Override
public void onCreate(Bundle savedInstanceState) {
    // Enable some Menu options
    super.MENU_HELP = true;
    super.BACK_ACTIVATED =true;

    super.onCreate(savedInstanceState);

    setContentView(R.layout.video_view);
    // A mix of different codecs and resolutions
    String fileName[] = {
            "v1.mkv",
            "v2.m4v",
            "v3_mpg4.m4v",
            "v4.m4v",
            "v5_and_mid.m4v",
            "v6_ipad.m4v",
            "v7_ipod.m4v",
            "v8.m4v",
            "v9.mp4"};

    v = new VideoView[9];

    v[0] = (VideoView) findViewById(R.id.v1);
    v[1] = (VideoView) findViewById(R.id.v2);
    v[2] = (VideoView) findViewById(R.id.v3);
    v[3] = (VideoView) findViewById(R.id.v4);
    v[4] = (VideoView) findViewById(R.id.v5);
    v[5] = (VideoView) findViewById(R.id.v6);
    v[6] = (VideoView) findViewById(R.id.v7);
    v[7] = (VideoView) findViewById(R.id.v8);
    v[8] = (VideoView) findViewById(R.id.v9);

    String root = Environment.getExternalStorageDirectory().toString();

    for (int i=0; i<9; i++) {   
        v[i].setVideoPath(root + "/Videos/" + fileName[i]);
        v[i].start();
    }
}

            android:label="@string/app_name"
            android:screenOrientation="landscape" />
    </application>

</manifest>

EDIT2：

添加以下行VideoView后设置：

Adding the following line after the VideoView is setup:

Log.i("MyVP", "" + v.isOpaque() + " " + v.isEnabled() + " " + v.isPlaying() + " " + v.isShown());

这表明假假真真虚假

it shows false true false false

我试图改变VideoView和根视图的阿尔法，但仍是结果是一样的。

I tried changing the Alpha of the VideoView and of the root View, but still the result is the same.

PS：几乎所有的文件（兼容的）可以嵌入Android的视频播放器应用程序打开。但我需要发挥他们的应用程序中...

PS: Almost all the files (the compatible ones) can be opened with the Video player application embedded in Android. But I need to play them inside the application...
