`simulcast` -\> `createPlainTransport()` -\> `ffmpeg`  
`ffmpeg` records the most simple stream (`scaleResolutionDownBy: 4`)

Question:  
Is there a chance to tell `plain_transport.consume()` to export only the best stream?

This is not true. By default a consumer will take the highest stream from a simulcast producer. Then there is an API in Consumer class to select which stream to consume (setPreferredLayers).

So there is something wrong in your setup.
