How do I use the Youtube API to check if a video is embeddable?_问答_开发者

Does anyone know how to check if a Youtube video is embeddable using the Youtube API? I've tried using this URL:

http://gdata.youtube.com/feeds/api/videos/47z7i79NuK8

but the response I get, pasted below, doesn't seem to have a field for embeddable?

As of the YouTube V3 API, there is an embeddable field in the status part.

E.g. https://www.googleapis.com/youtube/v3/videos?id=6CQEZ_kas0I&key=[yourkey]&part=snippet,contentDetails,status

"status": {
    "uploadStatus": "processed",
    "privacyStatus": "public",
    "license": "youtube",
    "embeddable": true,
    "publicStatsViewable": true
}

Looking at the YouTube API reference, it appears you have a couple choices:

Specify the "FORMAT" parameter when searching for a clip:

The format parameter specifies that videos must be available in a particular video format. Your request can specify any of the following formats:

5 - HTTP URL to the embeddable player (SWF) for this video. This format is not available for a video that is not embeddable. Developers commonly add &format=5 to their queries to restrict results to videos that can be embedded on their sites.

Or reference the yt:accessControl element:

The <yt:accessControl> tag indicates whether users are allowed to rate a video, add comments about a video, rate comments about the video, add a video response to the video, or embed the video on third-party websites. Another setting indicates whether YouTube can show the video on YouTube properties other than the YouTube.com website.

Syntax would look something like <yt:accessControl action='embed' permission='allowed'/>

So in your example it looks like the line yt:format: "5" tells you the clip can be embedded.

In YouTube V3 API, to return only videos that are embeddable, add videoEmbeddable=true parameter. You must also use type=video for this to work.

If you can use the new object-free way of showing a video you'll see that almost every video not viewable with the object tag now work flawlessy.

Syntax is:

You can't trust yt:accessControl at this time.

The XML should include <yt:noembed/> if the video isn't embeddable. Example.
