@0xtrr advises
The Blossom spec requires blossom server implementations to accept a file extension on the end of the hash in the url
"The endpoint MUST accept an optional file extension in the URL. ie. .pdf, .png, etc"

Damus still won’t play videos served from my Blossom server. Do you know why? Anything I can help with?
@jb55 advises
Guessing its not encoded with the right pixel format -pix_fmt yuv420p with baseline profile. Thats the most common reason videos don’t play.
@0xtrr is this a your server fix, or is it an upstream blossom server fix?
It has nothing to do with the Blossom protocol or the server implementation, it's just how the video has been encoded in the first place. I'm no expert on file containers or encodings but I find it odd that it's playable everywhere else but not on iPhone.
I don't know if this helps but for this particular video, I downloaded it from Twitter using yt-dlp with the following command:
yt-dlp -f http-832 -o "%(id)s.%(ext)s" https://x.com/Cobratate/status/1832295110521881065

this is a video encoding issue, there's not much we can do on our end for videos which are not encoded for maximum compatibility
