Server Version#: 1.18.9.2578
Player Version#: Andriod app 7.30.1.16475 (90b25cf6)
I’m running plex in a docker on my Unraid server and i can’t seem to get my transcoding working, whenever i play a video and select to transcode it an error pops up saying:
“Something went wrong playing this video. Please restart the server and app”
I attached my logs, i’d greatly appreciate it if someone could take a look at them.
Any solutions yet for this problem?
I have exactly the same problem. Streaming on an Android TV box (Xiaomi Box)gives me this error as well.
Streaming the same movies or series on Android SmartPhone (also Xiaomi) is no problemn, playing via webinterface also no problem. Even with subtitles.
I was just able to fix it last week, although i’m not certain if the following is what led to the fix,
I read on multiple forums that the issue is permissions on the specific transcode folder (although i set the permissions of this folder to 777 it still didn’t work). I also read of people having the same issue on “OpenMediaVault” and the problem there was that the drive which contains the transcode folder didn’t have the “exec” flag. i don’t know if this is the same case with Unraid (i dont have a degree in Linux :p).
So i tried mounting my temp folder of my server to the plex docker as the transcode folder, now when plex is transcoding it just uses my ram instead of saving it to the specific folder.
And i tried other things as wel like deleting the contents of the codex folder and restarting the docker afterwards to rebuild it. Like i said i’m not sure what led to it being fixed.
Right now everything works exept for one episode of a show when i enable a certain subtitle the transcoder crashes, not sure what’s that about but whatever.
If you have some more questions let me now, good luck.
Hi,
thanks for the reply, but althought I work in IT, this answer is very unclear to me.
I have Plex server running on 2 Synologies.
Should I change access rights on these devices? Is there a howto manual to perform this?
Or should I change something on the Xiaomi TV box? Same question applies. How?
Well, in order to transcode, plex (the server, not the client) needs a folder to temporarily save the video in while its transcoding. what i explained in my previous answer is that there most likely was a problem with the permissions of the drive on which i created this folder. so i instead pointed my plex docker to the ram of my server ("/temp" folder).
im not sure how this works on the synology OS but on unraid and linux you have to mount your paths to the plex docker so plex can access them, so i just mounted my /temp folder to the docker and told plex to use that folder (you can specify the folder in settings > transcoding > advanced settings > transcode path) to use as transcode folder.
like i said, i dont know how all this applies to synology OS though
ps. sorry for any grammar mistakes, english isn’t my first language 
Ok, did some further checking.
The temp folder is blank, so it just uses the default temp folder. I think (rather hope) that because the App was developed by Flex, they would make sure that’s ok.
But, according to https://docs.google.com/spreadsheets/d/1MfYoJkiwSqCXg8cm5-Ac4oOLPRtCkgUxU0jdj3tmMPc/edit#gid=1274624273 (Link to NAS compatibility, provided by Plex, linked from https://support.plex.tv/articles/201373803-nas-compatibility-list/) my NAS is only capable of using Software Transcoding at SD 480p / 576p quality.
Is there a way to tell Plex Server only to use/force that quality? I can’t seem to find it.
i don’t know if you can limit that from the server side, but in the clients there is a setting to limit the “remote” and “local” quality.
Does it work when you set the quality to setting you mentioned ?
I tried a few settings. All the built in movies/series/shows work. Even in high quality. But my own movies /series wont play for 1 second. They do play in the webbrowser (looks high quality) and on the Android App on my phone.
So either they block it, I am missing something or Plex doesn’t want you to see own movies on my own tv.
