I am submitting this issue as I can't seem to find a way have the chromecast maximum bit-rate respected. There is an option in the web browser and the android client to specify the max bit-rate however it doesn't seem to actually pay attention to it. Below there is a screenshot where I have specified a max bit-rate as 3mbps and the server dashboard shows that it is trans-coding at 5.6mbps, the same happens from the web app on android and from the native android app. I have attached the full server lot and some of the relevant trans-coding logs.
Please let me know if there is anything else that I can submit to assist.
