为什么我不能看视频模拟器？ [英] Why can't I see video in emulator?

问题描述

我见过类似这样的一些问题，但我想，以确保..
我失败对我的模拟器中运行视频。是不是一致？有谁成功地运行在模拟器上的视频？

I have seen few questions similar to this one, but I wanted to make sure.. I fail running video on my emulator. Is it consistent? Does anyone succeeded running a video on the emulator?

以下是code我使用：

The following is the code I use:

import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;

public class TTTTest extends Activity {
    /** Called when the activity is first created. */
 private MediaController mc;
 VideoView vd;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        vd = (VideoView) findViewById(R.id.VideoView);

        Uri uri = Uri.parse("android.resource://" + getPackageName() + R.raw.samplevideo);

        mc = new MediaController(this);
        vd.setMediaController(mc);

        vd.setVideoURI(uri);
        vd.start();
    }
}

samplevideo或者是MP4或3GP（在两种情况下它不工作）

"samplevideo" is either mp4 or 3gp (in both cases its not working)

main.xml中如下所示：

main.xml is as follows:

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

和清单是默认的。
谁能告诉我，如果我有一个问题，我的code？
附：我使用的android 2.2环境中运行的模拟器。

and the manifest is the default one. Can anyone please tell me if I have a problem with my code? p.s. I am running the emulator using android 2.2 environment.

推荐答案

仿真器确实有玩一些视频的问题，所以我一直做在实际设备上所有的视频​​测试。当视频确实在模拟器上工作，这通常是非常缓慢充其量（1fps，抵消音）。我也建议不要存放在APK视频，但是，这么说，我相信你需要另一个斜杠你的包名之后：

The emulator does have issues playing some videos, so I have always done all video testing on actual devices. When video does work on the emulator, it is typically extremely slow (1fps, offset sound) at best. I also recommend not storing the videos in the APK, but, that said, I believe you need another slash after your package name:

Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.samplevideo);
