I'm running into issues streaming very large uncompressed 4K movies from my M2 Mac Mini to Plex on my AppleTV (self.plex)

The error is saying there’s not enough memory. But not enough memory where? Anyone else running into this? Any suggestions for resolution?

If it's transcoding then that's a server error most likely saying it doesn't have enough memory to support live-transcoding. Try and force direct-playing by changing settings or as someone else suggested, use Infuse with direct-mode which avoids transcoding.

Don't listen to people saying not to use the ethernet port, recent ATVs have good gigabit ethernet ports and I've measured good performance on them in the past and I suggest the person saying that mistakenly believed you had an actual smart TV, not a device like an AppleTV.

Interesting, good point! I am trying to direct play (and thinking about it, one place Apple generally does not skimp, is on quality hardware.)

You probably want to check out the infuse app for playback on your Apple TV instead of the regular plex client. Once I swapped over every playback issue I was experiencing on my Apple TV went away.

I had not heard of this. Thanks!

Do you think you could post a picture of the exact error message? Also you could check the Plex logs through the web app and you should see the exact error and what component caused it. If I had to take a guess, I'd say your uncompressed movie has something that's causing the server to transcode (TrueHD audio or a forced HDMV subtitle stream) and the transcoding process is failing.

This is great info, thank you. I’m trying out the Infuse suggestion, but I’ll check tomorrow and see if the error persists.

Are both your devices using Ethernet or WiFi?

[–] Reverendender 2 points 1 month ago (2 children)

Both using Ethernet

[–] [email protected] 1 points 1 month ago

Do you have transcoding turned off? Sometimes it wants to play in "maximum quality" or something which is actually transcoding.

[–] [email protected] -2 points 1 month ago (1 children)

Try wifi on the tv apparently they cheap out on the Ethernet port and it's slow. But also make sure the video is direct playing. You might have to switch audio versions most 4k files default to 7.1 surround sound that is not supported by my smart tv Atleast

[–] Reverendender 1 points 1 month ago

Good advice, thanks! Audio is all set. My system is pretty ok, and I can do all formats.

Could be VRAM which is likely shared with the system's RAM for an integrated GPU.

I don't follow Apple's architecture much and I suppose you'd have to have hardware accelerated transcoding on, so I could be full of shit.

I had similar issues on my NAS before I built a streaming box with a dedicated GPU.
