Hi guys,
Plex was working fine until this week. I get an error for many files on the server that it cannot find the codec. I feel it was perhaps the latest update? How can I delete the update to roll back to a previous version?
This is the error message:
“Conversion failed. A required codec could not be found or failed to install.”
Unraid Version: 6.2.0-rc2
Plex Version 1.2.7.2987
Cheers, Josh
Log files please? Another user has reported a similar error which I’m tracking. I’d like to know which codec / codec server might have a problem
Hi ChuckPa, I’m only getting a 500 internal server error when clicking download logs under the help tab unfortunately
Cheers
a 500 error is not good. That’s the same ‘500’ we get from web sites… It is the same “He’s dead, Jim” error.
not knowing unraid, I can only suggest the default 1) restart 2) reinstall software if it doesn’t wipe your Library 3) if not cleared by this point, you will have to wipe and restart. Something corrupted it, or as I have seen with another user… he hasn’t updated in months and when he did, it was too much to change. All the codecs were out of date as well as the Database schema. It ended up corrupting itself in the schema upgrade (sqlite can do that if severe)
Things got even worse!
Tried restarting both unraid and plex, no change.
Deleted and reinstalled plex - all library data was still there no change, same error.
Then deleted plex and deleted the appdata/PlexMediaServer folder. Now it doesn’t launch!

did you delete the /config directory? As I read the docs, if that doesn’t exist and isn’t writeable by Plex, it won’t be able to initialize and start at all.
Also, when chown cannot change ownership of a directory, that means it doesn’t own it to begin with OR it’s not root. There is your first clue as to what’s happening. Ownership & user it’s being invoked as don’t match up… hence the other permission issues
I’m getting the same problem with playing content (Conversation failed…). I am able to access the log files which I can post here if you can direct me to which one.

Same problemfor me. Also with the 1.3.0.3059 MAC OS Sierra.
The info of the file says MPEG4 and AVI container
I’m getting the same codec errors on the most recent update, files I know that were working prior to the update now no longer play under the new update Version 1.2.7.2987.

So the update was giving me codec rendering errors earlier, but I’ve since refreshed the database again and some of the files that were giving me errors are now working. I will stay on top of it. Here is another file that was giving me hiccups.

To be certain all your codecs are up to date (this is something I’m noticing but do not have anything definitive enough to take to the devs), perform a multi-select of your movies/videos (enable multi-select, click the first, shift-click the last), then perform Analyze on them (left margin popup box). It will reanalyze the media and download updated codecs as needed.
ChuckPa,
I’m unsure why the update would have broken the codecs that were working before though, or are you just suggesting this for others to try?
Maybe that was a bug in the latest update…The DB and files need to be re-analyzed to fix any codecs it dropped during the update?
Getting Conversion failed. A required codec could not be found or failed to install. Openmediavault Plex install
What happened, which will be in your log files, is the codec download failure.
PMS 1.3.3 received a ‘codec revision bump’ to address issues. Those effected codecs (new minimum versions required) are called out directly by the Codec Manager and the Transcoder.
while starting a mkv file i get “not enough disk space to convert”
This is on a Raspberry PI 3 with a 500 gb usb drive
That helps me a great deal more than your log file.
Take the size of the movie (file size), roughly multiply by 2.5, this is the space PMS needs ‘just in case’ . It does this because it won’t know until it starts transcoding whether it actually has enough space or not. Plus, if you want to rewind, play again, and then skip forward, why waste that, so it saves it to disk until done.
Wherever you have enough space for that, Set the transcoder temporary directory there (Settings - Server - Transcoder). Make certain plex:plex has ownership and 755 permission to the directory.
Same problem anyone have a fix for this???
Experienced the problem recently, turns out it’s caused by plex.tv application having 500 error.
Not being able to log in into plex.tv will cause local video playback to fail.
Please remove that dependency please.
The otherwise normally reliable Plex.tv server did go down last night. From what I know at this point, the central Amazon servers (AWS), where the portion of Plex.tv you see lives, stopped working. I have not yet heard why this occurred. It could have been the app or it could have been Amazon and server issues on their end. That information hasn’t been reported yet.
I can concerned, and do wish to investigate further, how PMS could fail playback when it has previously downloaded the codec for that specific file during the matching and analysis stages when the file was first added to the library.
