Question

I installed all the needed tools and I wrote a simple YouTube downloader for WP7. The problem is with playing.. I tried several mp4 formats (listed here http://en.wikipedia.org/wiki/YouTube#Quality_and_codecs) with that code:

    new MediaPlayerLauncher() {
        Media = new Uri("http://localhost/asd.mp4"),
        Controls = MediaPlaybackControls.All
    }.Show();

But every time it says "Playback error". I ve read the WP7 codec support page (http://msdn.microsoft.com/en-us/library/ff462087%28VS.92%29.aspx) and it has multiple mp4+aac supports.

问题1:WP7能够操作YouTube视频(第一个圆形)?

问题2:微软是否接受我对市场的看法?

Answer 1

是的,它会发挥第4条作用(在市场上是你的管子),但是,投稿人只能玩 w。你们不得不在装置上测试其他格式。 http://go.microsoft.com/?linkid=9730558" rel=“nofollow”>.certification requirements(PDF) 用于视频特定部分。
