Buffering

Plex Media Server
1

My content keeps buffering;

My computer plex machine is a DELL R815 with 64 cores and 256 gigs of ram. It has a webserver running on it in addition which is hosting 1 webpage that is less than 5 megs. So, the plex server pretty much has the entire rest of the system to do things with; so having the CPU power shouldn’t be an issue here. It also has 4 different gigabit ports in addition to 2 40gigabit ports; several of the gigabit ports are in use to ensure that there’s plenty of bw available.

I’m also using cat 7, entire house is cat 7 with gigabit switches; so I can consistently transfer content around my network at full speed (so speed shouldn’t be an issue here).

I’m also seeing this with files that shouldn’t need to be decoded; I mean; it’s one thing to take a 10gig file and try to stream it and another to take a 300 meg file and try to stream it; I’d expect one to potentially require buffering but the other not at all; yet sometimes it does.

Wondering what gives?? What am I doing wrong?

Server Version#: 1.19.3.2793
Player Version#: 4.30.2

May I please see the DEBUG (not VERBOSE) logs of a playback session which buffers?

  1. Start Playback
  2. Let it play 30 seconds
  3. Stop
  4. Wait 30 for logs to flush
  5. Settings - Server - Troubleshooting - Download Logs
  6. Attach the ZIP file it gives you.

The original log file was like 250 megs because it includes all log files since I set it up; I wiped out all the logs and did it; this was the only log that showed up during things and after about 5 minutes of waiting.

So this example, it went about 3 seconds before needing to buffer again and again and again; this video (and many others like it), simply won’t stop buffering.

Please RESTART the server then RECREATE the problem.

If the files are deleted while PMS is running, there won’t be any file names in the directory with which to ZIP .

(deleting while open and then attempting to capture creates a Chicken & Egg problem)

Here you go.

It would have helped knowing this is a docker container before getting started.

Where is the transcoder temp?

“404” is “Not Found” . It can’t find the transcoded output.

Sorry; didn’t know that would be relevant. Yeah; it’s a docker with full access on the machine (so no limits on CPU or ram, etc). I dunno what a transcoder temp is? I don’t have that filled in in my configs; is that my problem?

8

I put /tmp in there for the folder (for the /tmp folder that should be writable to everyone); still buffering.

But I do see the transcode folder in the /tmp directory with about 100 files; so it’s writing to the correct location.

Actually; I’m not sure if that fixed it or not; but the video has been playing for 3 minutes without buffering; so maybe that was it!!!

11

Okay; I think we are good, it has been going 36 minutes without buffering; so that was it!!! Thank you much!!!
