Missing preview for MP4 movies using safari

[3zero2]

Description
Video preview for MP4 videos does not seem to be working.

Expected behaviour
Preview of MP4 video should display instead of the generic MP4 icon.

What is happening instead?
Generic MP4 icon is showing.

Additional context
Preview for MKV files works fine.
The /api/preview call is being made, however it doesn't seem to be working.

How to reproduce?
Browse to a folder with an MP4 movie.

It works for my testing-

Are you using docker or binary release?

I don't show notifications for preview error messages, but if you can view it on desktop, can you paste any console logs you see at the time?

Also show any backend logs you see.

It's interesting it doesn't work for mp4, that should be the most likely to work. Maybe there's something going on with file name or path. Backend logs may help.

There's also a media debug flag to debug this, but first I think we can probably figure this out from fronted/backend logs.

Your statement that it works on your machine got me thinking. So I tried on Chrome and it works fine. Doesn't work with Safari for some reason.

No relevant console logs really.

Also show any backend logs you see.
I can see the preview call being made

Ah. Safari. Thanks for testing that, I'll give that a shot and see what's going on.
