It uses the same player as many other websites, for example already supported 1tv.ru.

Here is another example:

• https://1plus1.ua/1plus1video/mir-naiznanku/specproekt/mir-naiznanku-rekordnyj-polet-svit-navivorit-rekordnij-polit-ukrayinoyu

This page has IFrame entry:

<iframe allow="autoplay; fullscreen" class="iframe-player" data-id="WRprbyMC" allowtransparency="true" allowfullscreen="" scrolling="no" tabindex="0" name="twttrHubFrameSecure" src="https://1plus1.video/video/embed/WRprbyMC?autoplay=1&amp;tl=0&amp;l=ua" frameborder="0"></iframe>

So, if page has iframe class="iframe-player" search its data-id="{id}" (in my example {id} is WRprbyMC)

And here is embedded player link:
