如何在Android中以不同的视图在一个布局中同时播放多个视频文件

在安卓系统中，我创建了一个三个面视图并排的布局，我想用不同的媒体播放器同时播放一个视频文件。但我面临的一个问题是，三个人都不能同时播放这段视频。他们中的一个或两个停止了显示。 如果我直接使用video view而不是Media Player类，问题仍然是一样的。 任何人都可以帮忙。问题出在哪里？它给出错误曲面创建失败本机错误。我尝试了不同的组合，比如一个文件在三个不同的视图中，三个文件在三个不同的视图中，但是问题还没有解决。 其他网站上的一些回复称，这取决于内核版本。 如果它取决于内核版本，请你给我任何android网站上的android文档链接，它取决于内核版本。或者是可以玩的，请给我代码的步骤。这是错误日志-

您没有给出任何代码示例

根据我的经验，我发现你可以用片段（至少在我用过的设备上）来实现这一点。请记住，有一个针对旧设备的片段支持库

---

因此，基本上用线性布局或其他东西代替视频视图，然后使用片段事务将线性布局替换为具有视频视图的片段。

您没有给出太多关于您到底尝试了什么以及有问题的区域是什么的细节，所以我只是做了一个小测试，看看我是否能重现你所描述的任何东西

我没有任何结论性的发现，但至少可以确认我的Galaxy Nexus（Android 4.0.2）能够同时播放三个视频，没有任何问题。另一方面，我身边的一个旧三星Galaxy Spica（Android 2.1-update1）一次只能播放一个文件——它似乎总是第一个

SurfaceView

我通过为Android 3.0、2.3.3和2.2设置模拟器，进一步研究了不同的API级别。所有这些平台似乎都能够很好地处理多个视频文件在不同表面视图上的播放。我用一个运行2.1-update1的模拟器做了最后一次测试，有趣的是，与实际的手机不同，它也毫无问题地播放了测试用例。不过，我确实注意到布局的呈现方式有一些细微的差异

这种行为让我怀疑，您所追求的东西实际上没有任何软件限制，但它似乎取决于硬件是否支持同时播放多个视频文件。因此，对该场景的支持将因设备而异。从实证的角度来看，我肯定认为在更多的物理设备上测试这一假设会很有趣

有关实施的一些细节仅供参考：

我设置了两个稍有不同的实现：一个基于单个

活动中的三个
MediaPlayer
实例，另一个基于三个单独的片段，每个片段都有自己的
MediaPlayer
对象。（顺便说一下，我没有发现这两种实现的播放差异）

一个位于

assets

文件夹中的单曲（感谢苹果），用于所有播放器的播放

这两个实现的代码附在下面，主要基于谷歌的示例实现——我去掉了一些实际测试中不需要的代码。其结果绝不完整，也不适合在实时应用程序中使用

更新：虽然它已经存在了一段时间，但我认为值得指出的是，谷歌展示了一项功能，“将两个视频流同时解码为两个TextureView。”。不确定它扩展到两个以上视频文件的效果如何，但与原始问题相关。

试试这个

public class CustomPictureActivity extends Activity {
/** Called when the activity is first created. */
VideoView vd1,vd2;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    vd1=(VideoView) findViewById(R.id.v1);
    vd2=(VideoView) findViewById(R.id.v2);
    vd1.setVideoURI(Uri.parse("/mnt/sdcard/file.mp4"));
    vd1.setMediaController(new MediaController(this));
    vd1.requestFocus();
    vd1.start();

    vd2.setVideoURI(Uri.parse("/mnt/sdcard/android.mp4"));
    vd2.setMediaController(new MediaController(this));
    vd2.requestFocus();
    vd2.start();
}

}

xml应该是这样的

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >

<VideoView
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="0.5" 
    android:id="@+id/v1"/>

<VideoView
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="0.5" 
    android:id="@+id/v2"/>

</LinearLayout>

首先，将您的三星Galaxy s-II与usb连接，然后键入命令提示符以安装您的系统-

cmd:> adb remount

然后替换文件并重新启动设备-

cmd:> adb shell
#reboot

我注意到，默认情况下，该设备使用opencore框架而不是libstagefright。opencore也有一些问题，这就是为什么中堂错误会抛出。但是libstagefright已经在android版本2.3中实现。查看build.prop文件，stagefright已禁用。这是启用libstagefright框架并确实支持libstagefright框架的最佳解决方案。您还可以播放MPEG-2TS文件，它支持同时播放多个视频文件而不会出现任何问题。

试试看，尽情享受。

看看这段代码，它就行了

video1=(VideoView)findViewById(R.id.myvideoview);
    video1.setVideoURI(Uri.parse("android.resource://" +getPackageName()+ "/"+R.raw.sample));
    video1.setMediaController(new MediaController(this));
    video1.requestFocus();
video2=(VideoView)findViewById(R.id.myvideview);
video2.setVideoURI(Uri.parse("android.resource://" +getPackageName()+ "/"+R.raw.sample1));
video2.setMediaController(new MediaController(this));
video2.requestFocus();

Thread view1=new Thread(new Runnable() {

    @Override
    public void run() {
        // TODO Auto-generated method stub
        android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_DISPLAY);
        video1.start();
    }
});

Thread view2=new Thread(new Runnable() {

    @Override
    public void run() {
        // TODO Auto-generated method stub
        android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_DISPLAY);
        video2.start();
    }
});

但这取决于您的设备是否支持多

视频视图。如果它不支持，它会给你错误，因为
这个视频不能播放错误（1，-110）
是什么让你认为这是可能的？如果可能的话，如何给我一些代码步骤。如果不可能，请说明原因。因为我不能同时播放所有文件。只有一个视频可以顺利播放。请提供代码您是否在Galaxy S-II v2.3.3上试用过。我遇到了上面提到的问题。如果它取决于设备或内核版本，您能否提供一份官方文档。@SuvamRoy：不，对不起，我没有Galaxy SII可供测试。我只能向您提供我的上述实证分析。由于不同的仿真器似乎不会遇到您描述的问题，我非常确定limitati
