The AppleTV 4K does a poor job of deinterlacing 1080i-60 content recorded from the LiveTV DVR. It plays the content natively without transcoding but just drops the frame rate down to 30fps. It was explained to me in an older thread that the ATV 4K hardware lacks the hardware necessary to do motion adaptive deinterlacing of native content. Well… I just evaluated Emby and their AppleTV app deinterlaces the same source content with perfect smoothness. It’s doing proper motion-adaptive deinterlacing. The server isn’t transcoding anything They claim to use the native tvOS media player in the latest version of their app (but can switch to MPV if the user chooses).
Can the devs look at this again? The hardware is clearly capable of motion adaptive deinterlacing.
OP here again. Maybe I’m not bringing this up in the right forum for feedback/feature requests. If not I apologize but I want to mention that in my Emby evaluation, I discovered a similar problem with one of their apps, specifically Roku. It had the same deinterlacing issue that the AppleTV app has with Plex. I brought it up on Emby’s community and their developers had it fixed and a beta version of their Roku app available within 48 hours.
It would be very nice if Plex’s dev team could look at fixing this core functionality.
The Channels app has been developing a version of the YADIF2x deinterlacer, which produces 60fps and is optimized for Apple GPUs using Metal.framework.
I think it’s pretty clear the Plex team has other things on their mind, which is a shame since core video functionality like this should always be a top priority.
