I just found out this discussion, most likely the issues in this topic are related to this problem:
As Iāve stated in that topic, whenever subtitles are enabled, playback either fails instantly, or it just stops after a couple of minutes.
I still donāt know whether itās normal that the subtitle track gets āDirect-Streamā while Video and Audio are Direct-Play.
Also my files just have at most 4 or 5 subtitle tracks, so in my case it doesnāt look like itās related to how many tracks are available in mkv.
I also notice this happens on LG TVs, (Direct Play video/audio + Direct-Stream subtitles), except thereās no error in playback, files seem to play fine.
Iām in the same place. I donāt have high hopes that this bug will be fixed so that Plex will work the way it did before the onset of the issue Iāve experienced.
This occurred to me after sLumpy was able to replicate the issue with files that had 33 or more total streams and posted this:
I hope I donāt sound ungrateful, I truly appreciate sLumpy working with us to confirm the issue that weāre experiencing is repeatable and precisely at how many streams it begins to manifest, but the tone of that post seemed to suggest the solution is to remux our files to make them play correctly with no mention of the potential that Plex may be restored to its previously functionality or that any more time was going to be spent on it, unless users could supply data of issues playing files with less than 30 total streams.
So for now, I have no expectation of the situation changing, so I will carry on remuxing my media to remove unnecessary subs/streams, unless a surprise fix is deployed.
No news at all, I still donāt understand how something as core as being able to play media properly and use subtitles is not fixed for almost a year?
Iāve not encountered the issue anymore. Maybe Iāve found the right configuration options that prevent it from happening, or maybe itās just luck.
I did a couple of changes though. Since the gsuite collapse I had to move everything to bare metal. Now I stream everything from a local NAS with a very low latency. Also the PMS version has been bumped to 1.31.1.6733.
Would be great if someone can record the screen while the issue is happening so we know we are talking about the same thing. I have my own recordings.
