Plex Remote Transcoder - A distributed transcoding backend for Plex

kopfpilot · July 7, 2016, 2:24pm

I added a prelimnary WIP verion of the docker-containers on github: https://github.com/kopfpilot/docker-plex-prt
though, slaves don’t register at the master yet.

For time beeing plex 0.9.96.6 is preinstalled and pinned to the version unsing the ENV VERSION, which can be overridden by adding -e VERSION= to your create or run cmd or the docker-compose.yml.

I still try to access ssh without the unknown host notification. Once this is solved, i will make the client self adding itself to the master.

See the Dockerfiles/ docker-compose.yml for needed volumes mapping and ports to expose. Slaves will reuse the volumes from the master-container, if you use “volumes-from”. Otherweise you have to take care of the volumes mapping yourself.

The Image is not uploded to dockerhub yet - which i plan to do, once i am ready. Means you have build it yourself.

build docker images: docker-compose build
run containers: docker-compose up -d

That’s what i could come up with the few hours i had the last past days. Mounting the shares is ment to happen on the docker host level.

Hi @wnielson
The new PRT SESSIONS function return the following errors any idea why ?

plex@SUPERMAN:/home/frodon$ prt sessions

Yes I will soon. Another question here. My Plex Database is growing none stop since I upgraded PMS to version 1 évent is thumbnail option is set to off. Have you seen the samethingg on your installation. ?

EDIT: Okay nstead of using ubuntu 14.04 I tried with a ubuntu server 16.04 and the PRT SESSION option is working fine. psutil version is different on that ubuntu version
python -c “import psutil; print psutil.version_info” (3, 4, 2)

I haven’t seen this before. I’m not sure what could be the culprit…

dbershev · July 14, 2016, 1:20am

@wneilson, Sorry if I missed it in a previous comment, but whats the upgrade procedure for going to a new commit?

Do a git pull then python setup.py install.

dbershev · July 14, 2016, 1:51am

@wnielson No error, but its not listing any sessions either. Is there a log I can check?

Are you sure there is an active transcoding session? If so, the log should be at /tmp/prt.log.

dbershev · July 14, 2016, 2:08am

@wnielson Yeah, I checked the log and a session is being transcoded. Just doesn’t seem to show up if I do a prt sessions. Not sure if prt is working correctly for me tbh.

@dbershev @igowas Finally squashed the bug. Try the latest version.

Thx its working now !
If you look at your system messages by using dmesg do you have a few lines like this

plex_transcoder[82410]: segfault at 0 ip 00000000005f8108 sp

I’m not experiencing any issue but I’m just curious. I think it’s happening when someone stop a media but I’m not sure.

dbershev · July 15, 2016, 12:12am

@wnielson Fixed it for me as well, thanks!

igowas · July 15, 2016, 5:55pm

@wnielson
The next version of PMS available with a plexpass " plexmediaserver_1.0.1.2396-c094d0d_amd64.deb " doesnt work with PRT. X(
