HEVC 10bit main is transcoding fine but HEVC 8bit main is not

[ilt]

Server Version#: 1.22.3.4523
I run pms in a docker on my 920+ with hw transcoding. Everything works like charm with 10bit HEVC. However with 8bit movies it just keeps spinning and then I get an error.

Player Version#: Version 1.31.1.2262-74fdc6b7

this is the error I get:

Error code: 4294967279 playback error. Any ideas?

Synology FAQ - Questions, Answers, and How-To's

FAQ 16: Increase the number of folders Plex can monitor Applicable to all supported versions of DSM. When the Linux ‘inotify’ table fills up, this will cause when Plex to stop automatically detecting new media you add to the server. It will also manifest when there are transcoder problems with Dolby audio codecs. Linux has a default table size which is static. We can increase this at will. On some versions it’s 8192. On newer kernels, the default is 65536 folders. This is easy to incr…

[Transcoder] [eac3_eae @ 0xac9800] EAE timeout! EAE not running, or wrong folder? Could not read '/tmp/pms-18eebc62-1993-4479-b33a-eb4d2e616f89/EasyAudioEncoder/Convert to WAV (to 8ch or less)/okzf5xfn94txj0a90fe7x4fb_539-0-4.wav'

[ChuckPa]

When you get EAE timeout, the most likely cause is an insufficient supply of Watch slots available (transcoder needs 2)

DEBUG logging, capturing the first 2 minutes from PMS start will confirm this.

It is confirmed by [Notify] ....... No space left on device.

[ilt]

When I try to do debug logging it’s filtered out?

[ChuckPa]

Settings - Server - General - SHOW ADVANCED

Enable Debug logging – SAVE

Now restart PMS,
wait 2 minutes

Settings - Server - Troubleshooting - Download Logs

Attach the ZIP file it gives you and I will review.

[ChuckPa]

thanks for the logs.

Is this where the media ends?

If so, notice there are no errors. This implies the table didn’t overflow (you have fewer than 8192 folders in use)

The next thing to ask: Where is the transcoder temporary directory ?
Is it on local storage or on the network somewhere ?

[ilt]

I am not clear what you mean by media ends. The problem happens only with specific movies (4k HEVC 8 bit) This media is nothing to do with it.

Here’s my docker compose for plex

This lives in a docker container that runs in a synology ds920+. I hope I am answering your questions.

Edit: I didn’t run the movie in question after I restarted the pms. Was I supposed to do that in that two minutes?

edit 2: attached a new log file with trying to play the movie

[ChuckPa]

Thank you… you read my mind.

I see it fail.

Where is the container stored (the /config directory and the /transcode )? On the Syno’s RAID or ??? ?

syno yep

[ChuckPa]

Everything is on the HDD (/volumeX) and not on a USB ?

[ilt]

the movie in question is also on the synology albeit different volume this one is /media

so docker and media are two separate volumes but none usb.

edit: but yes everything under /volumeX correct

[ChuckPa]

This is what I’m trying to track down as it’s the root of the problem. — Where /tmp is.

@ChuckPa

Could not read '/tmp/pms-51637b95-5a57-4607-a19d-983cb301dfde/EasyAudioEncoder/Convert to WAV (to 8ch or less)/n27qr2yovztchlv2zc702mfv_461-0-18.wav'

In your container definition, where does /tmp point to?

[ilt]

Good find. It’s interesting because it’s described in the docker-compose but when I look at the container definition I don’t see /tmp

See attached

[ChuckPa]

How about making one?

Is docker/appdata/temp available ? (that would be guaranteed on the HDD)
If so, add it ?

docker/appdata/tmp -> /tmp

[ilt]

Plex Media Server Logs_2021-05-25_21-57-17.zip (1.6 MB)

still have the same problem even after I created the directory. I wonder if I need to give permission to plex to write on it?

or maybe delete cache or something?

[ChuckPa]

You need to give the UID/GID you assign to the container
(PLEX_UID, PLEX_GID) to access the file system.

PLEX_GID = 100 (Synology users group)

You’ll need to look at /etc/passwd to see what the PLEX_UID should be.
Now extend that to give R/W to the directory on on the main Volume.

[ilt]

I am not entirely clear. Is PLEX_UID, PLEX_GID different variables than PUID=${PUID} PGID=${PGID} which I use by default? I have found this in /etc/passwords

plex:x:1026:100:Plex User:/var/services/homes/plex:/sbin/nologin

[ChuckPa]

If you’re using the UID/GID of user Plex then that’s fine.

By default, user Plex is only created for the native DSM 5 & 6 packages.

As long as the username exists , even though it will never be used by DSM 7, you can use it for whatever you like.
