Okay sorry, I'll just clarify a bit better.
It works with the built in gallery app, VLC and MPV without issue, I was just saying that I agree that the video has some issues when running on GoFile and the other site for some reason even though they can run other HEVC videos without issue.
The AV1 video didn't have an issue when trying to run on GoFile, which is odd since if anything, youd expect it to be the other way around, since HEVC is pretty damn old at this point, and like I said, other videos made with HEVC are able to run on those sites.
Was just commenting since the other reply had said I didn't read the other stuff properly.
