I might be misunderstanding the livekit docs. But can we actually hand it three presets here? Livekit docs stated up to 2 custom layers. Or are those standard preset no custom layers?
videoSimulcastLayers: [VideoPreset]
custom video simulcast layers for camera tracks, defaults to h180, h360, h540.
You can specify**up to two custom layers** that will be used instead of the LiveKit default layers.

nope its limited to three in total including the base layer.

Is this on purpose? or a left over of a dev setup?

this is part of debugging why h264 with simulcast is not working on iOS devices.

what makes this specific H264 presets? Aren't those just regular presets that could also be used with other encordings?

this PR is in draft -- this is part of debugging why h264 with simulcast is not working on iOS devices.
using h264 specific presets help finding out if the h264 macro-block constraint is the problem here.

why the mixture of VideoPresetsH264 and VideoPresets?
Recent research has confirmed that the number of devices lacking H.264 decoding capabilities is negligible.
In contrast, many modern devices come equipped with native H.264 encoders and decoders. By switching to the H.264 codec, we can significantly reduce CPU usage. Especially mobile devices will benefit, where it can lead to better battery life.
Furthermore, we add a 540p simulcast video layer.
