Ok there is something deeply weird here. Why would a propaganda show allow a Pole on to tell truth about Polish views AND broadcast it. I'm pretty sure it's not live
Yeah, when I have seen people talk out of turn in the past, they get spoken over quite heavily. My guess is either a) the reality of the situation is too apparent, so lying about it is pointless, and/or b) the Kremlin continues to paint themselves the victim with the world against them with this Polish truth happening to work with second half of the narrative.
I think you don't need to mirror the file. Just putting the original link here already fixes it. Links directly pointing to the mp4 file seem to be handled differently than the link being embedded (and expanded by clicking the symbol) here (tested below)
Was it actually a mistake by Ukraine, or was it a false flag fail? I mean either way, there's no way Poland is going to stop helping Russia get punched in the dick.
There seems to be a problem (across several platforms, but mainly Firefox) with recognizing the exact file format if the link is directly pointing to the mp4 file instead of having the video embedded on a page. Try saving the link as file and watch it from there.
PS: And as a test. Does this work? It's the same link, but now obviously here inside the page.
