Server Version 1.30.2.6563
This only happened recently with the past 2 Server Versions.
Just added a Movie, and Video preview thumbnails not being created with Scheduled Tasks (i.e. thumbnails when forwarding a movie)
Also the Movie Extras Thumbnails are blank.
Did the Plex Dance, didn’t help.
All previous Movies and TV Shows are ok, just the one new movie I added.
Anyone else having this issue?
Didn’t work
I set the hidden preference GenerateBIFKeyframesOnly to 0
Did the Plex Dance
And after the scheduled tasks ran (I waited 24 hrs), still no thumbnails.
Weird.
Is it a file format which your server is able to easily transcode, or the opposite?
Is it a particularly ancient file?
Just a Bluray->MKV->handbrake encoded m4v/mp4, 1080p.
Not that ancient a movie, its Conan O'Brien Can't Stop (2011) — The Movie Database (TMDB)
Just weird that Plex won’t create the thumbnails. 1st time this happened for me.
Which title it is, is irrelevant. The technical data of the encoding are much more interesting.
Did you use one of the default presets in Handbrake or did you make up your own custom encoder parameters? (don’t)
There is Plex media info XML or MediaInfo as a standalone inspector
I have a custom with minor changes from a handbrake default (i.e., not to load burned-in captions)
Attached in the xml:
file.xml.zip (10.4 KB)
That’s quite a weird and inefficient encode, at only 1 keyframe. Was this one of the constant bandwidth settings?
<Stream id="141226" streamType="1" default="1" codec="h264" index="0" bitrate="5951" codedHeight="1080" codedWidth="1920" colorPrimaries="bt709" colorRange="tv" colorSpace="bt709" colorTrc="bt709" frameRate="23.976" hasScalingMatrix="0" height="1080" level="40" profile="high" refFrames="1" requiredBandwidths="10082,6004,6000,6000,6000,6000,6000,6000" scanType="progressive" streamIdentifier="1" width="1920" displayTitle="1080p (H.264)" extendedDisplayTitle="1080p (H.264)"></Stream>
Not sure, I’ve been using the same handbrake settings for awhile.
Maybe I should try a re-rip/re-encode
BTW, These are my handbrake settings:
I see. Though it might be “quick & dirty”, nothing stands out which would cause issues.
Are these movie extras “local” extras or are you talking about the automatically provided trailers etc?
Do you let the server perform deep media analysis at nights?
There are local movie extras.
And its also the video preview thumbnails that are shown when you seek through the main movie that’s missing.
Yes, I waited 24hs after I set GenerateBIFKeyframesOnly to 0 so that the deep analysis was performed.
Let’s see what a re-encode does.
(and its not a big deal not having the thumbnails for 1 movie, just weird)
well, re-encoding didn’t do it, weird.
Took a lot at the logs (should have done this first), and found the problem.
I recently re-located the PMS to the attached HD that has my media files,
Did the move with a symbolic link, and everything else (as far as I can tell) is working fine, but the “Plex Media Scanner Analysis.log” is showing errors
(I tested with an SD card with PMS before the move, and there’s no errors)
I’ll post a separate thread on this here: Scanner Error after Relocating Plex Media Server Data Directory

External Drive was mounted with fstab as user which automatically implies noexec and since the Plex Scanner loads a shared library, exec is needed as an fstab option:
... /media/plex ext4 defaults,user,exec,nofail 0 2
