Hi,

I use Elementary OS, and the server icon doesn't appears in the tray, so i cant enter in settings of PMS, anyone know how to fix it ?

Thanks in advance

Old search had and new search has the same bug: it is case sensitive if I use cyrillic characters.
[Ubuntu 14.04.4]
[plex 0.9.16.4]
[Guide]
How to reproduce the bug?)
Go to webapp.
Try to search something with cyrillic characters , for example "Карточный домик" will find house of cards, however, typing "карточный домик" finds nothing.

Polled the guys, it is not only me

Hi All, nothing has changed via settings etc and all was working fine. I logged into my PLEX server today after I had added a few movies.
Then I noticed I was logged out and that my server was unclaimed. I have checked my account via the web and can log in fine via internet but my Server is also missing on that portal.
When I try to log-in I just get a there was a problem signing into PLEX.
I do use a BT home hub 5 but that hasn't caused me any issues in the past. I'm running PLEX via OMV and I'm on PLEX version 0.9.16.6

I am running Plex on Openmediavault and get stuttering & freezing when playing back a 1080p .mkv file. I get poor performance (stuttering & freezing) regardless of playback device Roku Stick, Smart TV, PC. Here's the catch!! If I open the same 1080p .mkv movie on the same PC with VLC media player the playback is flawless! Any explanation why I am seeing a performance hit when using Plex for playback??? I have Plex transcode setting to "Original" and am getting a popup saying server cannot keep up with the stream. Why is the server trancsoding on the fly when I have "Oroginal" selected in quality??

Thanks

I am having an issue with Plex Media Server 0.9.12.19.1537-f38ac80 on Ubuntu 15.10 (64 Bit) where some Albums are not showing up. Edit The tracks are erroneously included with other albums with similar names, typically with only digits diferring, e.g. 'foo bar vol1' tracks will appear 'under 'foo bar vol2' and the album 'foo bar vol1' is not listed.

As per my post and discussion at https://www.reddit.com/r/PleX/comments/3tkres/some_music_files_not_showing_in_plex_cant/

So at this point I have been using Plex for about a year. The server is running on Ubuntu 15.10-64 bit. All of the media folders in use are set with group 'users' which includes user 'plex'. I have had several music albums where none of the tracks would show up in Plex, one that I was able to fix and now several that I cannot. I don't understand what the problem is. The albums show fine on MiniDLNA server running on the same box (which also runs as its own user in the same group) so it is not a permissions issue.

Album 1: purchased from Google Play in 320KB mp3. Would not show up. Tried running tags through MusicBrainz Picard (as I usually do), no change. Adjusted file names using kid3 (to match filnemaes to id3 tags and check for illegal characters) no joy. Eventually transcoded from mp3 to mp3 and the reencode showed up. Only album to this point I have ever experienced this with.

Album 2: Adele's 25. Initially obtained this in mp3 format. Wouldn't show up, or rather it would briefly during a scan but then it disappeared again. Tried fixes as for Album 1 above but no good. Could access album via miniDLNA server and play it fine, ditto VLC. Got album again in FLAC. Still would not show up. Tried filename adjustment as above. Tried reencoding from FLAC to ALAC and back, no joy. Changed folder name before rescan. Tried rencoding from FLAC to WAV and back, no joy. Same as with mp3 version.

Albums 3: Today I have added a 10 album box set of Erik Satie to my library but only 3 show up. No obvious reason why only these three do not.

I looked in the logfiles for Plex soon after adding them and it could clearly see the Adele files but it doesn't want to add them to the library and I cannot understand why. I can't see the Satie albums from the box set 'complete piano works' now although I do see lots of older files that have been in the library for months.

Edit: So, as /u/4ndreasH pointed out on Reddit- the Adele tracks for the Album '25' are showing under '21'. I also have the same issue with an Erik Satie box set where the tracks from missing albums are incorrectly included with other albums. Seems to be an issue where the artist name and album are the same bar some digits in the album name. Now that we know what the problem is perhaps we can work on getting it fixed or find a workaround.

Hi all,

I just received my Pine64 through the post and thought I'd write up how I got PMS running on it.

The reason for wanting to do so? The Pine64 uses 64-bit architecture and is a quad-core Cortex A8 processor, so should pack a reasonable punch.

The first thing to be aware of is that this is an "arm64" architecture, and therefore we seem to need to jump through a few hoops before we can use the "normal" raspbian install mode and @uglymagoo's repos.

Step 1: Prepare the system

Download the longsleep Debian 8 image from https://www.pine64.com/downloads and burn it to an SD card. If you don't know how to do this, then the Raspberry Pi Foundation have a good guide at https://www.raspberrypi.org/documentation/installation/installing-images/README.md for Mac, Windows and Linux.

One thing I did notice is that the initial root partition is only 3.5G in size. You'll need to grow this using gparted or a similar tool before you boot, otherwise Plex will fail because it runs out of disk space.

Step 2: Install the software

Once you've booted the Pine64 successfully, we can proceed with the installation of the Plex Media Server.

I followed the instructions at http://www.htpcguides.com/install-plex-media-server-on-raspberry-pi-2/ however, when it talks about adding the debian package repository, you need to do a few things slightly differently via the following commands:

# Run add the ARMHF architecture to the Debian Packages that can be installed here
sudo dpkg --add-architecture armhf 
# Make sure that we install the correct version of the arm package
echo "deb [arch=armhf] https://dev2day.de/pms/ jessie main" | sudo tee /etc/apt/sources.list.d/pms.list
# Update the package lists
sudo apt-get update
# Install the media server and all the dependencies
sudo apt-get install binutils:armhf plexmediaserver-installer -y

This should then install and start the media server.

Issues

So far, the main issue I've found is the architecture one. I'm hoping that at some point, Plex will release an Arm64 version of the code natively so that this cheap little computer can handle it all :)

As with all small-board versions of Plex that I've tried, I've had the most success by using "Direct Play" instead of Transcoding, however the web interface is nice and quick to respond, and streaming to my PlexApp (sideloaded on to my NowTV) seems to work well.

I hope this is of use to some people! :)

So I recently upgraded by server. Got a new network card, an SSD for the OS (ubuntu) and got new hard drives for more storage. I've completed moving all the Plex Media Server data and reclaiming the server went smoothly. Everything is just about how it use to be except for this one small annoyance I cannot figure out which I imagine is something small. For some reason any of the newer TV shows I add it will show duplicates of in the "On Deck" & "Recently Added" section. The artwork will appear different from what I actually selected for the season also. Checked to make sure I do not have multiple files, and double checked the path on each. Same file format and I am 99% sure I do not have multiple libraries anymore. I haven't added a new movie yet but will try that here shortly and post to see if it does the same. I appreciate any responses. You guys have been great to helping me in the past.

Hi all,

Seems like my PMS only like to play smaller files, if it is larger files like movies from any Channel it will keep buffering and in the log it says: No Url found for .......
Does anyone got a idea what i am dealing with here and how to fix it?
The PMS plays smaller files like TV-Shows very well, it is only movie files...

I did attach my PMS Log and PMS Plug-In Log....

I am running PLEX Media Server on CentOS 7 but the movies library with content is located on the remote Windows server 2012 R2. Both servers on the same network and can see each other. How do I specify path to remotely connect to mount the network shared folder D:\MOVIES on the CentOS?

Thanks in advance...

Hi there. I recently upgraded to the Linux distro Solus 1.1 (2016) It's very nice, but there's only one problem... It uses eopkg. I was wondering if anybody had any luck running it on Solus. Any help is appreciated. Thank you!!

I have a plex server running on my Linux Mint machine. Things have been working great until today. There was a PMS update so I updated and after everything was gone in PMS. So I had to re-enable permissions and set up all the movies and let it download all the meta data. Remote connection wasn't working so I had to configure my router for port forwarding. Never had to do that for plex. Figured it was all fixed and no issue. Tonight I went to play a move on my Nexus Player on the same network. All the movies show up on there but when I select on it just loads and loads and loads until it says it lost connection to the server.

I then tried it on my android phone and I get the same thing. However, I got it to load on my laptop running Plex Home Theater but it took a while.

I also keep PMS installed on my laptop just in case I have a movie or two on there I want to watch. I started PMS up on there and everything loads up fine and plays. Could it be something with my linux server?

I'm at a loss. Any ideas?

Greetings, I just recently installed the most recent version of plex media server on my computer running fedora workstation 24 beta. I am having issues getting the service to run correctly. I have tracked it down in the logs and this is what is printed out. I am able to start the server just fine by running ./start.sh but not by sudo systemctl start plexmediaserver.

Hi

I am running a HP Proliant with multiple disks. Disk 2 has all my media stored on it. However, when I ask Plex to find movies in this drive, it didn't see the drive at first. I have now got it looking at the drive but whenever I open folders on the drive it just shows blank everything.

Any ideas please?

Thanks

I am having and issue with Plex Media Server 0.9.16.6.1993-5089475 amd64 on Ubuntu 16.04 where this issue is happening:

Plex automatically downloads subtitles, and when playing media with some of those subtitles the media won't play at all. It plays just fine without the subtitle.

I saw some others having this problem and they changed the locale, but that does not seem to be the problem here as the locale is set in the plexmediaserver systemd unit file through LC_ALL and LANG, and I have en_US.UTF-8 available on the system:

$ systemctl cat plexmediaserver
...
Environment=LC_ALL=en_US.UTF-8
Environment=LANG=en_US.UTF-8
...

I checked the logfile and found the subtitle file it tried to use while seems to be a gziped file:

$ sudo -u plex file "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Media/localhost/0/406a7fe73efc276a59f093928812ecc85c68f8a.bundle/Contents/Subtitle Contributions/com.plexapp.agents.opensubtitles/en/d19721416d7d5a7c3ad7d370eb3cb717a9e905c1.srt"

$ file gunziped 
gunziped: UTF-8 Unicode (with BOM) text, with CRLF line terminators

PS: I am not allowed to upload the compressed subtitle file.

Plex has been working flawlessly for over a year. Haven't made any changes other than updating Ubuntu Server. All of a sudden, I can no longer access Plex securely. I have no idea why. I didn't change or update any settings on the server (recently) or the router (ever).

Would appreciate some help on the matter. I'm lost.

I also noticed, when this happened, that I can no longer delete media through the plex interface. I know this likely doesn't have anything to do with the security feature, but despite me even opening up the file permissions to everyone I still can't delete any of my files through their interface.

Looking forward to responses.

Thanks,
M

A short preface: I used Gsnerf's gentoo ebuild to install Plex Media Server, and it's sadly a bit outdated but I doubt this is the problem here.

After trying Plex on my main workstation, I was convinced it was the optimal media solution for my home network, so I set about installing it on my gentoo-based gateway/all around server. I've managed to set it up succesfully, but I'm finding that scanning files is a lot slower than it was on my workstation. Both server and workstation are similarly specced, however: an i7-875K on the workstation, an i5-3470 on the server. Both have 8GB RAM, and the only significant difference (other than the obvious OS difference) is that the PMS database resides on a SSD on the workstation and on a HDD on the server.

The real issue seems to be something in the way it accesses the database, because Plex Media Scanner.log is riddled with these warnings, especially when scanning music:

Hi All,

For some reason PMS looks like it transcode slow on my new Desktop, it says like that in my PMS Log and PMS Plug-In Log, i will attach the one from PrimeWire as a eks. (together with my PMS Log). But PMS plays ALL movies slow, not just Prime Wire Channel.
My PMS is a Desktop Intel Pentium CPU G3260 3.30GHz × 2 (64 Bit) with 4 GB Kingston RAM and 500 GB. Harddisk.....
I run Fedora OS (Linux) on it....

Does anyone know how to make transcoding run faster? :)
I cant find anyone good answer to this in the forum....

Hello everyone

When I have a movie file named i.E. "3 Idiots.avi" and have external subs next to it like "3 Idiots.srt", serve that from my Linux server to my Xbox 360 Plex App, then it won't play these subtitles at all.

But the are played in Plex on my iPad. Just not on XBox 360. Smells like a bug when both behave differently.

Then I tried to rename "3 Idiots.eng.srt" and then it worked on XBox 360. Looks like a language code is mandatory.

In my opinion it is a bug for two reasons:
1. same Plex app client behaves differently on iPad + Xbox
2. language code should be optional, not mandatory. I have a huge movie collection of more than 500 movies, all with external srt files without the language code in their name.

What do you think? Does it look like a bug to you too?

As of Monday I'm unable to connect to PMS remotely. When I'm on the home network it all loads. The server itself is assigned a static local IP, and the router is configured to redirect all external requests to that one static IP. The router has also specified that static IP as a DMZ for testing purposes and it makes no difference. If I try to access the Web UI at https://app.plex.tv/web/app it simply shows this: https://i.imgur.com/IqlOVIJ.png. The same is true when accessing the server directly with its public IP, so https://my_public_ip:32400/web/app. The latter fact is strange, because if the server was unavailable, none of the Web UI would even load. I have several other services running on the machine, like SSH, which work normally, so connectivity is not an issue.

When looking at the server settings from the Web UI when in the home network, none of the IPs can be found: https://i.imgur.com/LFD9yX4.png. I'm running the latest version, 0.9.16.6.

Further, when on iOS, the server is unavailable (https://i.imgur.com/crAYM7C.png), but there's an exclamation point that, when clicked, somehow allows an "indirect" connection (https://i.imgur.com/AGyp8Sp.png), though I have no idea what that means.

Here is what the server log reports after just attempting to make a connection to the Web UI, and the Web UI stating that the server is unavailable:
