Android 视频不适用于流式传输

Question

我正在尝试按照代码播放视频。

public class VidplayerActivity extends Activity {

    private MediaController mc;
    String LINK = "http://***/test.3gp"; // 5 mb 

    @Override
    public void onCreate(Bundle savedInstanceState) {
        try {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            VideoView vd = (VideoView) findViewById(R.id.delta);

            Uri uri = Uri.parse(LINK);

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

            vd.setVideoURI(uri);
            vd.start();
        }
        catch(Exception e) {
            System.out.println(e.getStackTrace());
        }
    }

}

它在 android 1.5 和 1.6 中显示“抱歉，此视频无法流式传输到此设备”。视频详情如下

请阅读此文档:Android Supported Media Formats .仅使用 H 263 进行编码不足以成为在 Android 中流式传输的有效格式。

分辨率必须是:176 x 144 px 或 480 x 360 px 并且在文档的底部也有说明:

For video content that is streamed over HTTP or RTSP, there are additional requirements:

For 3GPP and MPEG-4 containers, the moov atom must precede any mdat atoms.

For 3GPP, MPEG-4, and WebM containers, audio and video samples corresponding to the same time offset may be no more than 500 KB apart. To minimize this audio/video drift, consider interleaving audio and video in smaller chunk sizes.
