When manually attaching a video link (from YouTube, Vimeo, etc) to a post using the Facebook web interface, Facebook automatically recognizes the link as a video, and allows
Instead try posting the link as the message attribute, it works for me that way.
message = your message + link
Here's how to post a video manually for YOUTUBE and VIMEO (hard to find online). Specifically if you want to have the LINK value pointing to a user's website/blog post where it originates.
//search for youtube.com and vimeo.com in the 'link' value
if (preg_match("/youtube.com/", $model->link) || preg_match("/youtu.be/", $model->link)){
if (preg_match('%(?:youtube\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $model->link, $match))
{
$video_code = $match[1];
}
$source = 'http://www.youtube.com/e/'.$video_code;
$picture = 'http://img.youtube.com/vi/'.$video_code.'/0.jpg';
}
else if (preg_match("/vimeo.com/", $model->link))
{
if (preg_match('/vimeo\.com\/(clip\:)?(\d+).*$/', $model->link, $match))
{
$video_code = $match[2];
}
/* Get Vimeo thumbnail */
$hash = unserialize(file_get_contents("http://vimeo.com/api/v2/video/$video_code.php"));
$picture = $hash[0]['thumbnail_medium'];
$source = 'https://secure.vimeo.com/moogaloop.swf?clip_id='.$video_code.'&autoplay=1';
}
$args = array(
'message' => //user's comment
'name' => //Title of post
'link' => 'http://...'//link to video on user's website
'source' => $source,
'picture' => $picture,
);
if ($this->_facebook->api("/".$this->facebookUserID."/feed", "post", $args)){
//posted to facebook
}
It appears that you have to extract the URLs of the actual swf in the page and the thumbnail image yourself. For example, this seems to work:
curl -F 'access_token=...' \
-F 'message=Link to YouTube' \
-F 'link=http://www.youtube.com/watch?v=3aICB2mUu2k' \
-F 'source=http://www.youtube.com/v/3aICB2mUu2k' \
-F 'picture=http://img.youtube.com/vi/3aICB2mUu2k/0.jpg' \
https://graph.facebook.com/me/feed
It appears that you can generate a valid source and picture from the page URL. The URL looks like http://www.youtube.com/watch?v=<code>
; take the code (3aICB2mUu2k here) and insert it into the URLs http://www.youtube.com/e/<code>
for the source and and http://img.youtube.com/vi/<code>/0.jpg
for the picture.
Don't use /feed, use /links (https://graph.facebook.com/me/links/ ) and simply POST "message" and "link" parameters using the YouTube /watch?v=ZL7nV7WwJKg URL format. /feed never worked for me, it just posted a static graphic and link but I wanted it to actually play embedded on Facebook as it does when you share the Video from YouTube to Facebook. Works like a charm.
Sharing as a link with /links instead of /feed seems to work better. YouTube, Vimeo, and Facebook videos are embedded as if posting manually.
curl -F 'access_token=...' \
-F 'message=Link to YouTube' \
-F 'link=http://www.youtube.com/watch?v=3aICB2mUu2k' \
https://graph.facebook.com/me/links
Sharing using the API any .swf file or video wont show a thumbnail on facebook unless its youtube . And that is by design as per facebook. Check this link
