Why VK API method video.search does not return direct links to videos?

Question

In contact with

I make a simple request:

$xml= simplexml_load_file('https://api.vk.com/method/video.search.xml?q=test&offset=0&count=1&access_token=token&v=5.37');

print_r($xml);

Returns everything except direct links to videos.
Although the documentation says that direct links to files are returned: {}

Answer 1

If direct authorization is used in your application , an additional file field is returned containing a link to the video file (if the video is hosted on the VKontakte server) or a link to an external resource (if the video is embedded from some video hosting).
