How to find out that the video is not allowed to be embedded on the site (VK API)?

Question

PHP

Good afternoon! It was necessary to implement the possibility of embedding a video from VKontakte into the material on the site. I figured out how to get and parse the link, but noticed an interesting feature. Some videos work fine inside the contact and you can get the embed code, but when I run the video on the site, I see something like this:

Which parameter in the API is responsible for detecting such errors? I actually googled and looked in the docs before asking this question, but found nothing. Maybe I didn't search well.
It is also interesting that the video from the example does not contain materials of a sexual nature, however ...)

Answer 1

There is no such flag in api.
The only option that I know of is to check the embed link yourself and see if there is a message about the embedding ban.

Answer 2

SELECT `d1`.`dialog_id`
    FROM `dialog_users` AS `d1`
    JOIN `dialog_users` AS `d2` ON `d2`.`dialog_id` =`d1`.`dialog_id`
    JOIN (SELECT `dialog_id`, COUNT(*) AS `count`
              FROM `dialog_users` 
              GROUP BY `dialog_id`) 
        AS `c` ON `c`.`dialog_id` = `d1`.`dialog_id`
    WHERE `d1`.`user_id` = :user1 
        AND `d2`.`user_id` = :user2 
        AND `c`.`count` = 2
