I have Direct Play and Direct Stream enabled within Plex. I DO NOT want to burden my QNAP with this if it’s not needed. The server CPU constantly is pegged upwards of 89% usage or greater.
I only stream to my Samsung TV.
Can I simply disable Transcoding on Plex?
Should I disable Direct Play or Direct Stream?
I ask these questions because I want to remove the jitters and pausing of movie playback and I feel like the Transcoding tying up the CPU is the root of the problem.
It’s more than just one file, so giving the specs on one file is not going to do you any good.
I have 4 Samsung TV’s that have the same issue.
My question was not to analyze one file and tell me it’s the file, I can do that already myself. The files are only affected when playing on any of my TV’s which are all different models.
My question is more so surrounding if I need Transcoding or not in general for watching movies.
What hthighway said is exactly why I’m asking… plex looks up profiles based on what your client is to figure out how to play the file.
If you’re using DLNA it gets messy as sometimes it can’t figure it out or uses a default but it’s an easy fix… just edit the profile if you know the TV can handle it
The app I think has a spot you can tell it to use different profiles… at least on android it does… never used Samsung one myself
So… back to my original questions
DLNA? App?
Some example media info of something that doesn’t play?
Not using DLNA. No sure what app you’re talking about other than Plex.
So based on what HtHighway mentioned, I can simply turn off transcoding completely on Plex and see if my videos play fine without it.

Do you have the client(s) setup to play “Original” file?
If you want additional help pick one TV to start with to make it easier for everyone to follow the thread. If possible start with your “best” Samsung TV. Chances are good that once the problem is found it may apply to them all anyway.
I’m either using the Plex app directly on my Samsung TV or on my Amazon Fire TV device.
Local Quality - Original
Remote Quality - 20 Mbps
Online Quality - Original
But as I type this I realize the Video Frame Rate on this particular movie was 24p. Would this then force transcoding if a remote person (outside of my home) was watching this movie? Can the assumption be made that if I was watching this at home (Local) it would not transcode?
Frame rate shouldn’t trigger a transcode
I’m seeing several complaints in the forums about <2016 Samsung TVs suddenly always transcode since 1.3.x
That file for sure should play direct… could you provide logs from an play attempt?
Narrow down what Plex is doing and why it thinks that file can’t be played native

Sort of where I was going with my thoughts on this and why I asked.

Please give me an idea of what “Orca” is and if that’s something I can install on my Plex TV? This is the first time I have heard of that.
Thanks
Newer Samsung TVs (2016 and up) will use the Plex App made my Plex which is available through the Samsung apps store.
Older TV’s will use the Plex app made by a forum user named Orca, it will be the only Plex app you see in the Samsung app store if you have an older TV
Does your Plex App look like this image?
If so then you are using the Plex app made by Plex, not Orca

Is there a way to simply disable transcoding completely on my QNAP Plex app so that no transcoding occurs?
No there isn’t, and if it was disabled then anything that gets transcoded now would just not play on the device you’re currently using. Otherwise, if it could DIRECTPLAY, it would.
I was going to get some logs, but with remote play now after changing “remote quality” to “original” the remote movie I was testing with is not transcoding. Then I had that remote person who has access to my library try another movie and it’s still not transcoding as of yet.
So still just waiting to see if I get the same problem as I mentioned in the beginning of this thread, then upload logs, unless someone needs them now.
