在WPF中集成Vimeo的视频(Integration of Vimeo's video in WPF)

 我们在Vimeo上有一个帐户，我们为特定的观众显示一些视频。 他们是私人，我们定制ui的播放器以禁用共享的选项。 观众可以做的唯一一件事就是播放视频。 
 
 此外，我们定义了一个可以集成视频的特定域。 所以我们在这个域上有一些网页，我们整合了这些视频。 
 
 在Firefox，Chrome或Edge等网络浏览器中，如果我们访问此域上托管的网页，则无需显示和播放该网页。 但是如果我们使用WPF webbrowser，网页可以显示视频，但Vimeo的播放器会显示一条消息，我们可以通过我们定义的隐私设置来阅读视频。 
 
 为什么在Firefox或其他浏览器中，我没有任何问题或消息来播放我的域名（我们想要的）网页上的视频，而在WPF webbrowser中，Vimeo的播放器不允许我播放我域中同一网页上的视频？ 
 
 感谢帮助。 

We have an account on Vimeo where we display some videos for specific viewers. They are privates and we customize the ui's player to disable the share's options. The only thing that the viewer can do it's play the video.
 
Moreover, we defined a only one specific domain where the videos can be integrated. So we have some webpages on this domain where we integrate the videos.
 
In a webbrowser like Firefox, Chrome or Edge, if we go on a webpage hosted on this domain, there are no issue to display and play it. But if we use the WPF webbrowser, the webpage can be display with the video, but the Vimeo's player show a message that we can read the video because of privacy settings that we defined.
 
Why in a browser like Firefox or other, I don't have any issue or message to play the video from a webpage on my domain (what we want) and in the WPF webbrowser, the Vimeo's player don't allow me to play the video on the same webpage in my domain ?
 
Thank's for help.
