java - Android Brightcove 视频播放器

Question

我为 Android 应用程序的 Bright Cove 视频播放器编写了示例代码。我是用静态 URL 做的。我很困惑如何使用视频 ID 播放视频。我在下面发布了完整的代码。

//URL of the video we are playing
private static final String VIDEO_URL = "http://cf9c36303a9981e3e8cc-31a5eb2af178214dc2ca6ce50f208bb5.r97.cf1.rackcdn.com/lucy_gets_shot_1280x720.mp4";

//String array of ad URLS
private static final String[] googleAds = {
        "http://pubads.g.doubleclick.net/gampad/ads?" +
        "sz=400x300&iu=%2F6062%2Fhanna_MA_group%2Fvideo_comp_app&ciu_szs=&impl=s&gdfp_req=1&" +
        "env=vp&output=xml_vast2&unviewed_position_start=1&m_ast=vast&url=[referrer_url]&" +
        "correlator=[timestamp]",
        "http://ad.doubleclick.net/pfadx/CABdemoSite;kw=acb;sz=728x90;ord=29078349023890482394823;dcmt=text/xml",
        "http://pubads.g.doubleclick.net/gampad/ads?sz=400x300&iu=%2F6062%2Fhanna_MA_group%2Fwrapper_with_comp&ciu_szs=728x90&impl=s&gdfp_req=1&env=vp&output=xml_vast2&unviewed_position_start=1&m_ast=vast&url=[referrer_url]&correlator=[timestamp]",
    };

Answer 1

使用 Catalog 通过视频 ID 获取视频。

Catalog catalog = new Catalog("BRIGHTCOVE MEDIA API TOKEN");
catalog.findVideoByID("1234567890", new VideoListener() {
  @Override
  public void onVideo(Video video) {
    videoView.add(video);
  }
  @Override
  public void onError(String error) {
    // Handle error
  }
});
