Transcoder error when recording

General Discussions Plex Features
1

Hi All

I’m hoping someone can help me with this.

I have completely uninstalled Plex (to try and fix the bug with recordings getting stuck at 100%) and then re-installed the latest 1.9.2 version but since re-installing recordings fail within 30 seconds of the recording beginning. The error I get is:

There was a transcoder error

I have checked that the temp folder used for transcoding allows full access and when the recording starts I can see the files getting created until it fails so I don’t think its a permissions issue.

I am running on a Debian 8 based server (Openmediavault).
I also tried downgrading plex to version 1.7.4 but the same issue continues.

Thanks in advance. I have attached the logs.

I had this alot after 1.61, 1.91 has ran flawlessly for me so I didn t think twice and updated to 1.92 and the first 3 programs that should have recorded all reverted to this issue. Its frustrating that every time they add features something seems to significantly get broken.

I have now downgraded to version 1.6.1 and recordings are now working again

Spoke too soon. Although I was able to record with 1.6.1 I was not able to play back any of the recordings. Only videos in other formats such as mpeg4 would play.

In my logs I see [Transcoder] Unknown decoder ‘mpeg2video’

Anyone know how to fix this?

Thanks

I’m now testing running Plex in a Docker container (the official Plex one) and now running 1.9.3 but exactly the same issue continues. I get “there was a transcoder error” every time I try and record.

I’m contemplating reinstalling my entire server from scratch but I have a horrible feeling I’m going to be back in the same boat.

Well in the end I did reinstall from scratch which did mostly resolve the transcoder error (although it still happens occasionally).
Now running Plex natively rather than Docker on Ubuntu 16.04

Just wanted to chime in with a potential solution. I started experiencing this issue yesterday and it was driving me nuts. It seemed to come from nowhere, and nothing I tried would resolve it. I scoured the internet for advice and never found a solution, but I did notice several of the threads mentioned a mounted disk for the Plex library. My ubuntu server mounts a Synology NAS via NFS for library storage. I took a look at my NFS settings and made some changes that seem to have fixed this issue for me.

Initially I had this line in /etc/fstab

x.x.x.x:/volume1/media /mnt/nfs/media nfs rw,soft,intr,user,rsize=4194304,wsize=4194304,timeo=14,vers=4

I had set that up with “rsize” and “wsize” based on a recommendation I read on some forum somewhere, which supposedly made the NFS faster.

I decided to remove the “rsize”, “wsize” and “timeo”. I also realized I was missing the “0 0” that is supposed to be at the end. So now, my /etc/fstab entry looks like:

x.x.x.x:/volume1/Media /mnt/nfs/media nfs rw,soft,intr,user,vers=4 0 0

I rebooted, and now recordings work! I had rebooted half a dozen times beforehand and recordings hadn’t fixed themselves, so while possible that the reboot randomly fixed it, I think it has to be related to the nfs settings. I’ve also noticed a few less issues as well, my Nvidia Shield would randomly stop playback of non-tv content, which no longer seems to happen.

Anyway, I don’t fully understand the NFS settings to know how that may have helped, but something to try!
