We’re seeing a reproducible issue when the producer is an iPhone in portrait mode and the receiver is on Windows using Edge or Firefox. I have reproduced this on the Mediasoup demo project.
Producer: iPhone camera, portrait orientation.
Receiver: Windows desktop.
Browser results:
- Edge: remote video tile is black (audio continues).
- Firefox: video is visible but rotated 90° left.
Is the correct approach here to handle rotation manually at app level for affected browsers (e.g. custom rotation signaling/CSS rotation)? Or how is this supposed to work?
