Hi,
I am having trouble with some high quality 4k media, specially movies with details like:
The media is not playing smoothly... I do have a regular stuttering on various clients.
I first thought it is my network, which is backed up by a wifi b.a.t.m.a.n. mesh with 2.4 Ghz and 5 Ghz (Wifi 6).
I do have constant rates between involved clients with ~160-250 Mbps throughput (messured with iperf3). Messured from a AP, which connected to the interface jellyfin is using, I see rates between 50-96 Mbps when playing such media.
Jellyfin v10.8.13 (TrueCharts) is running on TrueNas Scale with additional Nvidia P400. Since all tested clients are capable of the format (It shows direct play im media information and there is no ffmpeg log), I ruled this out as a bottleneck. I do use the Traefik, provided by TrueCharts with TLS to connect to Jellyfin.
Every now and then, I for sure have a log entry like this:
Hoewever, this happen every 10-20 minutes and is not like the stuttering, which happens every 20-60 seconds.
How can I best debug this stuttering? I remember, with Emby, back in the days, I was able to get debug information on my client. What are your tips to get this fixed?
Thank you very much,
Christian
