colev14 Posted June 9, 2024 Posted June 9, 2024 Hello, I'm having an issue watching movies from my Unraid server streaming to Plex, Jellyfin, and even Kodi over SMB. I've done a ton of troubleshooting and it seems to be specifically high bit rate movies from the array start stuttering every few minutes. I'm not sure if there's something I can do to fix the issue. I have never had it in the past. I have my Unraid Server with a 2.5G NIC and the Shield has a gigabit ethernet. I've run an iperf test and gotten 800Mb between both devices. I exported it and attached it below. I have benchmarked my drives and attached an image below. I've also attached my diagnostics. The test file I have been using is a 58GB 4K DV Remux of Barbie. The file is on Disk 8 of the Array and buffers constantly when playing on Plex, Jellyfin, and Kodi. I copied the file to my nvme cache drive and it plays back fine with no stuttering on Kodi, so it seems like a read speed issue. But based on the benchmarks, I have plenty of speed I think? There is nobody else watching anything on the server. I'm kind of lost on what to do. I have not had this issue until recently. iperf_2024-06-09_12-29-04.txt unraid-diagnostics-20240609-1217.zip Quote
JorgeB Posted June 9, 2024 Posted June 9, 2024 Disk speeds look normal, I assume there's nothing else reading or writing to the array when that happens? Quote
colev14 Posted June 9, 2024 Author Posted June 9, 2024 Yes, nothing else reading or writing to the array. Quote
JorgeB Posted June 10, 2024 Posted June 10, 2024 Try using a disk share to see if there's any difference. Quote

I went from running plex directly on the server to running it on another machine and having the other machine connect to the media share on unraid via nfs. That reduced the frequency, but I will still occasionally get buffering. For me locally it is only on 4K high bitrate movies. I did just hear from my brother who lives on the other side of the country that he has buffering, but only on Survivor. I only share 1080p content and I have 250mbps upload. He is 3 timezones away so nobody else is awake and watching stuff. He is the only one. It makes no sense. One of my friends mentioned that they had weird nfs issues with unraid and moved to Truenas. The issue hasn't occurred frequently enough for me to explore doing that. Hoping an update might fix the issue down the line. Quote
Veah Posted January 5 Posted January 5 Had something similar from an Emby perspective. My solution was on the Emby client 'Playback' settings to lower the 'Home network quality' and 'Internet quality' speeds. Those settings look like this: 4K - 120 Mbps 4K - 40 Mbps 1080p - 60 Mbps 1080p - 25 Mbps .. with several in between. If you can find something similar, try walking the setting down to something that works. Quote
