vkoembed
The module works with oembed_providers and adds VK Video oembed provider into the list /admin/config/media/oembed-providers.
VK Video doesn't provide endpoint for oembed, but it has VK API, where we may find "video.getOembed" method. So oembed data may be retrieved via API. But anyway oembed_providers needs to have endpoint from where data may be read.
That is why the plugin creates local endpoint (/vkoembed/api/getVideo) and transfers oembed VK API call via this endpoint. Because of that it may not work on local web server where usually self-signed ssl is used (you will see a specific errors in the drupal log).
Features
It defines oembed provider, which may be used to configure oembed provider's bundle and then to create a media type, which allows to retrieve VK Videos.
Post-Installation
As far it requires VK API access, you need to create web app in your VK businees account. And then you have to provide service access key.
/admin/config/vk_api/settings
After that you need to utilize VK Video ptovider (/admin/config/media/oembed-providers), to create new/update existing eombed media type (/admin/structure/media).
