Generating Thumbnails fails for certain Videos

[watn3y]

The bug

A few weeks ago, I noticed Immich throwing some errors when trying to generate Thumbnails for certain Media. These were mostly Videos, but I there might also have been some pictures (I'll have to double-check when I have the time).

I grabbed the file in question, started a new Immich instance, and was able to reproduce the error.

Note that this issue occurs with both webp and jpeg.

The OS that Immich Server is running on

Docker 26.1.2 on Debian Bookworm

Version of Immich Server

v1.104.0

Version of Immich Mobile App

Platform with the issue

• Server
• Web
• Mobile

Here's the Video file. Hopefully you can use it to reproduce this.

I did some more debugging, and this only seems to happen with the Thumbnail Resolution set to 480p.
