[Feature] Disable "Play video thumbnail on hover" on server-side

I have searched the existing feature requests, both open and closed, to make sure this is not a duplicate request.

The feature

When you scroll through your album on web, the "Play video thumbnail on hover" feature causes full videos to load in the background even if you very quickly scroll past them. The result is that quick scroll down can generate multiple GBs of traffic, which your device may or may not be able to keep up with gracefully. On a mobile connection, certainly not.

Thankfully, this can be disabled at the user/client level under "App Settings" > "Play video thumbnail on hover". Good.

The request is that this can be overridden at the server level, and applied to all users. Reason being, I have less than technical family members who use the server, and have a habit of scrolling down years worth of photos to get to a single thing. Inevitably this causes their instance to lock up while the server serves multiple GB worth of requests.

An alternative would be the option to default this to off. Another alternative would be to switch to only loading like 10 frames for thumbnail videos, or just keyframes, or something like that, so you're only loading KB instead of MB/GB.

Thank you

Are you using Caddy or another reverse proxy?

[tayl]

Yes, Caddy for SSL termination and cert management.

There seems to be an odd interaction somewhere with caddy and http/3 where requests don't get canceled properly on the backend, I've heard reports of this before. On other setups it seems to work perfectly fine and doesn't cause any sort of overload/traffic spike.

Interesting, so the proper functionality would be that scrolling fast generates the request, but quickly cancels it after it's out of view? Is there an existing request tracking that? If so I can try and reproduce and see if I can come up with anything on my end.

I suppose that would help in this case, though I still believe there's value in being able to control this server side.

Immich does actually cancel it, the problem is elsewhere, more near the caddy side but I haven't nailed it down exactly
