Error "failed to add element to pipeline: video output bin" when running the ingress service locally (Ubuntu 22.04)

[rootdrew27]

I have built the livekit ingress service binary using mage and then after installing gstreamer with Homebrew (LinuxBrew) I have linked the proper plugins with a wrapping script:

#!/bin/bash
export LD_LIBRARY_PATH=/home/linuxbrew/.linuxbrew/lib:$LD_LIBRARY_PATH
export GST_PLUGINS="/home/linuxbrew/.linuxbrew/lib/gstreamer-1.0"
exec ingress "$@"

Unfortunately, I get the following error(s) in the ingress logs when I attempt to connect with OBS:

I am attempting to set this up on Ubuntu 22.04.

Any help is appreciated, and I'd happily provide more information about my setup.

For anyone stumbling across this issue, I am currently using LiveKit's Ingress docker image to workaround my issue. I've also wrote a guide for getting the service running locally (along with a local livekit-server), as the guide provided by LiveKit was not sufficient for me.
