更新:我将我的视频信息插入此https://bitmovin.com/demos/drm并且播放没有问题。这让人相信这不是 CORS 问题

我已经尝试了很多次,试图让我们的 DRM-ed 视频在 chromecast 上播放。看起来它可以很好地运行非 DRM 视频,即使我弄乱了元数据(显然这不应该对视频产生影响)

const playbackConfig = new cast.framework.PlaybackConfig();

playbackConfig.licenseUrl = DRM_LICENSE
playbackConfig.protectionSystem = cast.framework.ContentProtection.WIDEVINE;
playbackConfig.licenseRequestHandler = requestInfo => {
  requestInfo.withCredentials = true;
};

我用我的实际视频拦截了发送的请求:

playerManager.setMessageInterceptor(
  cast.framework.messages.MessageType.LOAD, loadRequestData => {
    loadRequestData.media.contentId = "videoUrl.m3u8"
    loadRequestData.media.contentType = 'application/x-mpegurl' 
    var metadata = new 
               cast.framework.messages.GenericMediaMetadata();
            metadata.title = 'robocop in action';
            metadata.subtitle = 'robocop';
    loadRequestData.media.metadata = metadata
    loadRequestData.media.HlsSegmentFormat = cast.framework.messages.HlsSegmentFormat.FMP4;
    loadRequestData.media.HlsVideoSegmentFormat = cast.framework.messages.HlsVideoSegmentFormat.FMP4;
    console.log(loadRequestData)
    return loadRequestData;
  });

最终,一切都汇集到这个最终功能中:

context.start({playbackConfig : playbackConfig})

让 DRM 内容在 Chromecast 上运行究竟需要什么?

谢谢

原来我需要将 CORS 标头传递到我的播放配置中:

const playbackConfig = new cast.framework.PlaybackConfig();
playbackConfig.licenseUrl =
  "DRM-LICENSE-URL";
playbackConfig.protectionSystem = cast.framework.ContentProtection.DRMMETHOD;
playbackConfig.licenseRequestHandler = requestInfo => {
  requestInfo.withCredentials = true;
  requestInfo.headers = [
    {
      "origin": ["*"],
      "responseHeader": ["Content-Type"],
      "method": ["GET", "HEAD"],
      "maxAgeSeconds": 86400
    }
  ];
};
