Help with identification - YouTube cactus

[Nino_G]

I would appreciate if someone could help with identification of the cactus species portrayed in this You_Tube video:

Plant I'm interested in is portrayed from 0:05 to 0:38 at the very beginning of the video. It looks like Escobaria to me but I've never encountered similar species before.
Thank you in advance and best regards,
Nino

The video is very poorly made. My best guess: Mammillaria pottsii

Escobaria minima/sneedii/leei ?

Thank you both for the attempt, but I think it's none of the plants you mentioned. It remains a mystery to me.
