[3.1.4] Camera rotation not applied to WebRTC stream (works in preview & Android app)

After updating to firmware 3.1.4 with the new WebRTC streaming, the Rotate camera button no longer affects the live WebRTC stream on Prusa Connect and PrusaSlicer.

 

Behavior:

✅ Rotation works on the still preview image

✅ Rotation works on the RTSP stream

✅ Rotation works in the Prusa Android app (preview + live)

❌ Rotation is not applied to the WebRTC stream when hitting Play on connect.prusa3d.com or in PrusaSlicer

Looks like the rotation transform is missing specifically from the WebRTC pipeline — RTSP and the Android app apply it correctly.

 

Setup:

Camera: Buddy3D (standalone "snowman", not the Core One version)

Camera firmware: 3.1.4 PrusaSlicer: 2.9.4

Tested in Chrome and Firefox on Linux Prusa

Android app: rotation works correctly

Also hitting a second bug on 3.1.4 that might be related:

Stream quality is stuck on SD and I can't change it. Selecting HD or FHD just throws "communication failed" every time on RTSP mode. Same on the Android app, PrusaSlicer 2.9.4, and connect.prusa3d.com (both Chrome and Firefox).
