Beamer has been my go-to app for streaming a file from my Mac to my AppleTV.
Unfortunately, the app immediately crashes on Big Sur (or maybe just on M1 Macs, I’m not sure which), the developer has been unresponsive (their ‘support’ link on their website leads to an expired page, and their Twitter page is idle since September 2018).
Without getting into something like Plex, I am looking for an app that can basically take any video file and send audio and video to the AppleTV.
Interestingly both JustStream and Elmedia Player are available via Setapp. I don’t really like JustStream being menu-bar only. Elmedia Player’s UI is ugly, but I’ll give it a go.
Thanks!
Update:
MPU folks recommended Airflow (which also works well), but I’m going to stick with Elmedia Player for now, since I already have Setapp. The UI isn’t pretty, but it works nearly the same as Beamer did.
I’ve run into that with various Apple technologies in the past, like AirDrop. For the longest time, it was unreliable whenever I tried it. It’s still a little funky, but I’ve taken to using it preferentially when moving screenshots to my Mac.
AirPlay was the same way, years ago, but AirPlay 2 was an improvement and with newer devices and operating systems throughout, it seems to be pretty solid now.
