Some videos not working on mobile

There are some videos here which do not play on mobile, no matter if I reload the page or if I keep hitting the play button, at least on my Samsung Galaxy A05s. However, these videos play fine on my PC.

Such as these:

I also tried downloading one of the linked videos, but my phone's video player would not play them.

Nice hi-res videos. Work just fine on my galaxy s22ultra. Must be your phone, sorry.

I'm having the same issue on Firefox on Android

Seems like the videos are 60 or 50 fps maybe that has something to do with it. it's rare on this site. it plays on my phone using Firefox on Android

Wow! The quality of the videos are so awesome.
