MS Bot Framework VideoCard

问题

Can someone please explain how you use the MediaUrl for the VideoCard? I've tried just adding the video url to the CardMedia which loads the media player but I can't play the video.

And whatever I try with MediaUrl I just get an error saying MediaUrl is not a funtion.

var url = new MediaUrl("Test", "https://www.youtube.com/watch?v=0i4v0Texqco");
var vid = new builder.Message(session)
          .textFormat(builder.TextFormat.xml)
          .attachments([
              new builder.MediaCard(session)
                  .title("Test title")
                  .media([
                      builder.CardMedia.create(session, url)
                  ])
          ]);
session.send(vid);

Thanks for any help!

Per the VideoCard documentation and the MediaUrl documentation the url must be the one to the source of the video.

Using a YouTube URL in the VideoCard is not supported.

However, recently a "YouTube Card" was recently added to the WebChat/Emulator. If you are using WebChat, you might consider using that. See this and this for more information.

For the Javascript solution the following code works pretty well, please note that it has been tested in bot framework emulator.

const {ActivityTypes } = require('botbuilder');
async playYoutube(context)
{
    const reply = { type: ActivityTypes.Message };
    reply.attachments = [this.getInlineAttachment()];
    await context.sendActivity(reply);
}

get the object:

getInlineAttachment() {
    return {
        name: 'YoutubeVideo',
        contentType: 'video/mp4',
        contentUrl: 'https://www.youtube.com/watch?v=-2JRiv3Mycs'
 }

hope this helps. Cheers
