The bug

I'm unsure if this is the expected behavior, but while scaling my installation across a second device, it appears as of now, to be impossible to mix hardware acceleration APIs between worker nodes.

The OS that Immich Server is running on

Debian 12

Version of Immich Server

v1.115.0

Version of Immich Mobile App

n/a

Platform with the issue

  • Server
  • Web
  • Mobile

Your docker-compose.yml content

standard

Your .env content

standard

Reproduction steps

Hardware:
1. Main server with an Intel GPU supporting QuickSync Video
2. A separate "immich_server" worker node on a second machine with an Nvidia GPU supporting NVENC

With the webui configured at:
Administration > Server Settings > Video Transcode Settings
to use the QuickSync Video for transcoding, immich expects and requires the additional worker node to also use QSV.

A likely workaround would be to use the VAAPI backend instead, as it is more widely supported across GPU vendors, however, per the docs, use of the hardware specific APIs is generally preferred. The docs also currently state immich does not support hardware decoding with VAAPI, so CPU load would also increase somewhat.

Ideally, individual configuration of hardware transcoding would be possible for each worker, allowing each worker to utilize their preferred acceleration API.

Relevant log from worker node equipped with Nvidia GPU attached below.
