What is the problem?

What exactly do you mean by invalid URL?

[lachuza]

the first url in my comments dosent works, but the second yes and is the same video for both. follow the two links and you will see.

Again: what exactly do you mean by "does not work". Post the output of youtube-dl https://vk.com/video-51189706_456244634 from this machine.

vk uses hotlink protection maybe because of that

Case 1 (dosent works, you cannot download the video from the url)
youtube-dl -g https://vk.com/video-51189706_456244634
https://cs6-8v4.vkuservideo.net/video/hls/p18/14f300a3c3c5/index-f2-v1-a1.m3u8?extra=RlT5yNqZ9KxoU-4nAtWVUGvD

Case 2 (WORKS you can download the video from the url)
youtube-dl -g https://vk.com/video-51189706_456244634
https://cs6-8v4.vkuservideo.net/video/hls/p18/476d34e200fe/index-f2-v1-a1.m3u8?extra=vjNW9POhFcqoaSE_7NIWKL_V4zagIwd9-AtfMCLvLrfluxEpDJCo9R6ueCNQML_UljDYSWc9h2NnA1OuD0t7BE33QbQkwIXJrg11GafSuX6kBCJ26hSZuEDbIpfUBQCUeft1ogr8f61M

@lachuza You could not download the extracted url from another machine/ip because VK uses hotlink protection which allows to access from the same machine/ip
