The good news I have figured out how to get the majority of the shows I want to watch actually working now, but there are a few annoying cases where they just won’t work and I would like to know the cause if possible. I’ve provided logs if it helps.
There are problems across multiple different shows/formats so I can’t pin it down to a single cause.
I should mention I have transcoding disabled by default because the hardware I’m using isn’t very powerful (it runs the majority of videos just fine at 1080p which is basically good enough).
I have noticed sometimes that the file I’m running has a non-standard resolution (e.g. 1904x1080p instead of 1920x1080p) and in other cases, the audio format is OPUS and for some reason Plex Web in Chrome doesn’t support that. There may be other reasons, but I’d like to know if there is an effort by the devs to make these non-standard or unpopular audio formats work with Plex along with any other problematic files.
The CPU, N2807, has 456 Passmarks of performance. This is well below the Plex recommended minimum of 700. Most NAS platforms have 2000 Passmarks.
The video you’re attempting to play was badly encoded and is non-standard at the container level.

If you wish to use that CPU for Plex, I recommend -
Preprocess your video files BEFORE giving them to Plex
Correct the non-standard geometry
Convert the non-standard / unpopular audio formats to what a typical browser will play – AAC
Fix permissions and naming to be standard

Not sure if I should continue this thread but after a lot more time with Plex, I’ve started seeing a pattern in what files work and what ones don’t and why they’re breaking. If there is a better way to make a proper bug report, let me know as I would like this to get resolved if possible as it doesn’t seem incredibly difficult at least from my perspective.
The short version: 99% of video files work until you turn on subtitles (and I’ve tried at least 30 or 40 different series mostly anime). Subtitles are really breaking things quite hard. I have tried enabling them after a file initially worked, and it immediately crashes. And vice versa, a crashing file immediately works when I disable subtitles for that one file.
Is this a known issue? It would really make my Plex experience a lot better if it could handle subs without crashing so badly. And yes I’ve tried the various subtitle settings (like “Only image formats”) and the only one that makes the problematic files work is disabling subtitles completely.
Use a more powerful computer as your Plex server machine.
This can handle the transcoding which will be necessary to “burn in” the subtitles to the video picture, if the used client device doesn’t understand the subtitle format natively. Different client types understand varying subtitle formats. Your best chances are when using SRT format subtitles.
Use client types which understand not only SRT subtitles, but also the VOBSUB and the PGS subtitle formats. (The latter two are exclusively found on DVD and BluRay discs, which is why many Plex player devices don’t support them natively.) “Plex for Windows/Mac” should be able to play these natively though.
As you can see, you can either update your server or your client devices.
tbh I was hoping for this to get fixed rather than have to transcode or to use a different device (I’m on a LG TV, Plex is the only media server software that works on it).
Is there a way to send a bug report?
If it helps, the subs on the problematic files are usually the embedded/burned-in type.
There is nothing to fix, if the device itself (in this case the LG) is not supporting the subtitle format.
Sorry, but this is inconclusive.
There is a difference between “embedded” and “burned-in”.
It also doesn’t tell the actual format of the subtitle in your files. Details matter.
Please post the contents of the Plex XML info
of one affected file.
One of the XMLs for the problematic files. I can get others if you need. Also I think I have come up with an acceptable workaround to this problem. I haven’t tried it yet but I think it may be possible to extract the subs using some kind of video-editing software and then just to run them as external subs files rather than embedded. If you’re saying the LG device is the problem then my guess is this will help as usually films work fine with a SRT file (or whatever format subs).
Just as I thought.
These subtitles are in PGS format. (ripped from Bluray)
Very few players can understand this format. So when you play such a file in Plex, the server will try to burn-in the subtitles into the video picture, because it knows that your client won’t be able to display the subs otherwise = Transcoding
Just in case anyone else comes across this thread, I found out that the .sup subtitle container format that many of the broken anime files use can be converted quite easily to .srt using SubtitleEdit.
