MY PROBLEM:
Yesterday a friend of mine called me and said a series he is watching doesn’t work anymore. So I tried and he was right, from one day to another (nothing touched/changed on Plex or the Server, no restart or anything, it’s ALL the same) the series and a lot of other series and films can not load (but not all films/series).
The failure-message is: “Dieser Server ist nicht leistungsfähig genug, um Videos konvertieren zu können.” in engl.: “This server is not powerful enough to convert videos.”.
But the server is chilling at 10% CPU and the series was an anime at 480p, and AT THE SAME TIME I can load instantly a 60GB 4k Movie without problems.
How and why?!
Today, the next day, I tryed the same episode again and everything works fine. -what the heck was that?
“Video transcoding” is deactivated in Plex under “Transcoder”.
And yes “Upload-Speed” is set.
Why should some work and some don’t?
When nothing changes? -that’s really witchcraft, isn’t it?
PS: It still doesn’t work for my friend today. -disapointing
BTW: When U deactivate the “Transcoder” under “Transcoder” it isn’t deactivated -nothing new to me, I always hopped it got fixed, but PLEX didn’t fix it.
The “Turn video transcoding back on” was the thing.
But my question is, to understand the it-problem: why does it stop working, after doing nothing. -that’s why I used the word “witchcraft”, I’m not an IT-Pro, but to me it doesn’t make sense.
Not sure. If it’s the same file giving problems then a remux or re-encode of it will probably fix whatever is happening. Otherwise we will need to dig deeper.
Enable the server debug logging (but NOT the verbose logging).
restart the server
play the problematic items
inspect the Plex Media Server.log file immediately afterwards.
Look out for lines beginning with MDE:
There you will likely be able to determine the reason why the server thinks a transcode is required.
Plex can handle mp4/x264 files just fine.
The log lines Otto is referring provide technical details of what exactly is causing/requiring the transcode (e.g. bitrate too high, unsupported encoding level… and yes, if the format/coded isn’t supported, that’ll be in the logs too).
Okay, I’ve tested now more video etc.
I don’t want any video-transcoding, because at 4k it uses all my CPU-Power and I can’t use my NAS normally.
I see, that it cann direct play a 4k movie, but 90% of the time (it’s total random) it transcodes the 4k movie into 1080p, and my NAS is at 100%. Internet is free @45Mbit/s and my friend has a 50Mbit/s downrate.
I turned on transcoding because after this the error-message doesn’t show up. -like this user here in this thread said:
“Turn video transcoding back on and the error will go away and/or increase your set upload speed.”
So I need to turn on transcoding to stop transcoding, then all movies work but it transcodes randomly and uses the whole CPU.
How can we fix this, or will there be an update? -I need to fix it, because I bought this NAS for 4.000 € and only for this.
There are plenty of 4K files which exceed this bandwidth at least momentarily.
45 Mbps might be enough for the “4K” which you usually get from commercial internet video streaming services.
But their “4K” is very different from the 4K which you can find on UHD Bluray discs.
The singular bandwidth value you might be seeing in the properties of a video file doesn’t even tell half the story. Because it is simplistically computed by taking the size of the file and dividing it by its play duration.
However, that only works for files which have a constant bitrate. Video files pretty much never have constant bit rates.
Open the Plex media info XML of one affected video. Look out for the XML properties named requiredBandwidths="...
These will tell you exactly the real bandwidth requirements to stream this file without requiring transcoding.
This error message indicates some difficulty with either access permissions or codec downloads. It could also be caused by a too low inotifytable size.

I recommend you to dive into the threads which deal with the “peculiarities” of Plex on Synology, particularly with the changes brought in DSM 7.
If you are used to operate Plex Server on Windows, take some extra time to learn the general principles of Linux platforms.
-nothing new to me, I always hopped it got fixed, but PLEX didn’t fix it.
