Another one try on vk.com/video_ext.php error (seems it truncates id and hash from URL)

So. We have a link of an embedded video on VK: https://vk.com/video_ext.php?oid=-153313854&id=456239545&hash=0df9a596a1159f31
The video plays without any problems in an incognito mode. But when you try to download the video from this particular URL it ends with an error.

I assume the reason is this line:
[debug] Command-line args: [u' - sv', u'https://vk.com/video_ext.php?oid=-153313854']
Where mandatory part &id=456239545&hash=0df9a596a1159f31 is missing.
