Your link doesn't work, but I still found what you mean. I think at that point I'd probably look into the Microsoft Wireless Display Adapter or something similar instead, as Miracast on Linux actually works quite well with GNOME Network Displays. But my current goal is not having to connect any additional hardware to the projector, so I will be looking into pyatv for now.
I can't find any "funtax" user in the linked openairplay repo, but it appears that I have completely missed pyatv's ability to stream video. As long as it can stream video I think I can make it do screen mirroring too. Thank you very much, I will be looking into pyatv now!
This launcher looks super cool, does anyone bychance know if it works on FireTVs?
I was ok with the FireTV launcher up until they made it autoplay ads with sound everytime you turn the damn thing on.
This could be a long shot but if it's a Samsung Galaxy Tab S, the battery connector solder joints kinda die after a while, which can either be fixed by reflowing them or by applying pressure (I have a tablet with that issue). You could try pressing on the battery connector and see if it works then.
Most mobile devices won't work without batteries. The best way to work around this is to supply it with 4.2V (anything between 3V and 4.2V will do) over the battery connector.
It'll be a collab with HP!
