Also this isn’t a Plex owned backup, so use at your own risk.
thank you for the update. I hope this happens soon. I have an arc pro b50 card collecting dust wanting to be used lol
I came to this thread too late, the links already were down when I received my B50 ;(
Thank you guys!
EDIT: oh my, it really works, my B50 is finally allowed to make its existence worthy!

Wait for builds with Battlemage support..
The private beta discussed in this thread (1.43.1) has Battlemage support, and feedback from Battlemage owners was explicitly requested. The public beta (1.43.0) does not, and—in context—that’s what @ChuckPa was referring to when he wrote “Battlemage support is not included in this beta.” Cheers.
Yep. I missed 43.0 vs 43.1. Thanks for pointing it out.
is there an update on release dates?
No update at this time.
As previously stated, Chris will let us know when he has builds.
Just opened my Plex and I see this:
Server update channel is set to public. I have cleared all my settings from Chrome and Safari, both show the same?
1.43.0.10467 is now the public release. It is available on plex.tv (except for QNAP).
Announced on reddit.
Plex just hasn’t yet updated the release notes thread.
Thank you.
I was looking there as well, couldnt find any info what so ever .
so does this mean i can put my B570 in the server and it should work?
No, you have to wait for 1.43.1
Also there will be specifically stated in the changelog that Battlemage is supported, and it’ll probably be posted about here. Wouldn’t be surprised if there’s another test build or two in here before that too.
based on a reply from our mate chuck (not Chris so not gospel) 18 days ago 11th of january most likely under 2 months before at very least the public beta that you can load in from within system without special test build download
To the folks up the chain of replies who suggested the wayback machine, thank you so much. I was able to grab the 64b .deb that way. And now I’m waiting on someone to finish watching something so I can run the installer. Been wondering what the heck is going on with my B580 and finally came across this thread.
Anxiously awaiting the official Battlemage release!
Edit: Installed and working. Hardware transcoding on the B580 is working. Thanks!!!
