AVFoundation issues - Can't play URLs from firebase

[juliaYamamoto]

Hi! I am having an issue trying to play a video that I get from Firebase.

Error:
Error Domain=AVFoundationErrorDomain Code=-11828 "Cannot Open" UserInfo={NSLocalizedFailureReason=This media format is not supported., NSLocalizedDescription=Cannot Open, NSUnderlyingError=0x600003f987b0 {Error Domain=NSOSStatusErrorDomain Code=-12847 "(null)"}}

According to apple, Code= -11828 is The system can’t open the file because it’s in an unrecognized format.
I couldn't find what Code=-12847 is.

These video urls don't come with the extension of the file, like .mov or .mp4. I tried to apply it manually without success.
They work on browser and they work when I try to use AVPlayer.

Any idea of what might be going wrong?
I really want to use this library as it's very complete and well done :)

I'm sorry I can't give you any links, but I can give you any other information that could help.
Thanks!

You can check if response.mimeType matches "video/..."

I'm facing the exact same problem! I'm providing a public URL of a video/mp4 file and it throws this error!
