facebook video thumbnail image URLs?

For example, this is the url to a facebook video thumbnail: http://vthumb.ak.fbcdn.net/vthumb-ak-sf2p/v10822/239/59/505867356/t505867356_382364037356_272.jpg

There are quite a few obfuscation identifiers in there which prevent me from doing something like taking a video id and making a thumbnail link.

The reason I'd like the thumbnail is to be able to populate a 'navigator' band with t开发者_如何学JAVAhe various videos from the app.

Anyway, anyone know of a way to get the video thumbnail url?

find your video id, and this the url of thumbnail https://graph.facebook.com/VIDEO_ID/picture
