我试图在Sony GTV（Android 3.2）上的VideoView中播放视频，当VideoView加载时，我得到了一个“无法播放”的视频。对话。我视频中ffmpeg -i的输出是：

根据：https://developers.google.com/tv/android/docs/gtv_media_formats h264基线应支持aac音频，但B帧支持有限。有没有办法确定基线配置文件是什么问题？

视频在运行ICS的平板电脑上运行正常（我没有使用Honeycomb平板电脑进行测试）。

我目前还没有索尼设备进行测试，因此从Logitech Revue中取出了这个logcat。奇怪的是，这里出现了更糟糕的问题，因为在设置视频URI时，Revue只显示黑屏，任何键盘输入都会产生ANR。

启动视频的代码如下：

public void onStart() {
    super.onStart();
    MediaController mc = new MediaController(getSlideActivity());
    mc.setAnchorView(mVideo);
    mVideo.setMediaController(mc);
    mVideo.setVideoURI(Uri.parse("https://view.vzaar.com/933735/video"));
    mVideo.start();
}

我将视频播放代码修改为AsyncTask并且它不再在Revue上崩溃（虽然视频没有播放）：

new AsyncTask<Void, Void, Void>() {
        @Override
    protected Void doInBackground(Void... params) {
        Looper.prepare();   
        MediaController mc = new MediaController(getSlideActivity());
        mc.setAnchorView(mVideo);
        mVideo.setMediaController(mc);
        mVideo.setVideoURI(Uri.parse(mSlide.getMedia()));
        Looper.loop();
        return null;
    }

    @Override
    protected void onPostExecute(Void v) {
        mVideo.start();
    }
}.execute();

在上面的AsyncTask中添加一些日志记录语句后，我发现它永远不会越过调用＆＃39; setVideoURI＆＃39;。

的行。

Google TV上的VideoView与标准Android不同，因此根据Les Vogel（Google TV DevRel），URI需要直接存储到文件中。
