MKV file plays with VLC but fails with Plex

azzdoo · July 11, 2018, 10:23am

Hi, I have had a few issues with these types of files, apps like VLC and google drive can play them no problems, yet Plex is unable to.

I am running plex media server on Linux with Docker.

The only thing I have noticed, are these files, when played on VLC, have subtitles on by default.

Here is a link to the sample file - https://drive.google.com/open?id=1_ywvAm6oM6mpLifsBQJO_LpxN0QlFC6q

Here’s detail on said sample file

Any assistance on this would be greatly appreciated

Define ‘Plex’. Which particular Plex client is used?

What hardware do you use to run Plex server?

Your sample file played on mu Roku3. The subtitle were off by default I did enable them and were displayed aswell. I had no issues playing the sample file with or without subtitles.

Sorry, should have mentioned I was talking both the plex web client and via chromecast, neither seem to work for me

The hardware I’m using is an old intel i5, 4gb ram, SSD, and an old Thecus NAS storage device I cobbled together. Not state of the art equipment so that could be a potential issue

The weird part is my plex server works awesome 90% of the time, just fails for files like this.

How can I find out whether I need a hardware upgrade or if it’s something else?

OttoKerner · July 11, 2018, 10:18pm

The video is not critical. It has a rather low bitrate and doesn’t exceed the abilities of the common playback devices.
I am not so sure about the audio, though. There might be some chromecasts which don’t play E-AC3 audio. Browsers don’t play it either.

So, the audio needs to be transcoded. For this, the Plex server needs to download a codec from plex.tv (only once). Does your server have a working internet connection?

azzdoo · July 11, 2018, 10:23pm

Yes it does, though I also happen to get a lot of 404 errors in chrome dev tools when I try play the file in plex web

Here’s the chrome dev log example

I have a hunch this is the usual thing with virtualized PMS:
The plex data folder, (or more precisely, the transcoder temporary folder) must be mounted in such a way that execution of program code is allowed in these mounted folders.
How this is done properly, I cannot say as I’m more of a Windows guy.

I will leave that to the expert on all things Linux, @ChuckPa

azzdoo · July 11, 2018, 11:14pm

Awesome, no need for the rescue @ChuckPa, your tip about the temp folder was enough to fix my problem

Same issues occuring to me were had here at the forum link below.

https://forums.plex.tv/t/error-transcoder-ac3_eae-0x2fd4f40-eae-timeout-eae-not-running-or-wrong-folder/189917

All I had to do was include this to my docker run command and the file started playing. Mounting the tmp folder to my operating system means plex can now execute on this folder as expected.

-v /home/user/Containers/Plex/tmp:/tmp

It’s also worth noting my transcode folder was also mounted this way

-v /home/user/Containers/Plex/transcode:/transcode

Thanks so much for the assist @OttoKerner , I am now one very happy dude
