Very poor menu Performance on clients and other errors

[Hallo951]

Hello,

I have the latest jellyfin (10.8.4) running in Docker on my NAS (Synology D920+, 1TB SSD read/write cache, 4 GB RAM (still upgrading to 20 GB)). The largest library is about 1000 movies. My TV (LG OLED 65 BX with webos 5) is connected via WIFI over 5G. I installed the jellyfin client on the TV via the dev mod. To 90% everything works. What does not work properly is the following:

1. The performance of the menu from the client on the LG TV is very slow and sluggish especially within the very large library. For libraries with less movies it is a little better but also not very good. On another client, for example the cell phone, almost everything runs much better. What can I do to make it run smoother on the TV?

2. When I want to play a 4K movie with a 7.1 audio track on the TV, it is transcoded via hardware transcoding (QSV). This also seems to work normally, but the movie stalls every 10 - 20s, as if it is buffering something in between. Is this due to the still too small RAM or what? This observed faltering occurs on all clients.

3. Filtering by video type (e.g. 4k movies) does not work for me. This behavior also occurs on all clients.

I'll try to address these by point.

1: Have you changed the library display settings at all, or are they at the original settings? I ask because some people disable paging, which will really hurt TV performance.

2: Does transcoding also stall on any other clients, or just the TV(s)?

3: As above, does that happen on the phone/computer too?

Hello,

about your questions:

1. I had changed the library display to show me all movie entries instead of 100. But since this was even slower, I changed the setting back to 100. I also activated the setting for displaying the backgrounds. Otherwise I have not changed anything. What do you mean by "paging"?

2. yesterday I increased my RAM from 4 GB to 20 GB. After initial testing, a hardware transcoded movie on the TV now ran completely through without jerking or anything. So it seems to have been due to the RAM being too small.

3. yes unfortunately. On the phone, the problem still occurs despite RAM increase with automatic adjustment. However, if I manually set the resolution to 1080p, the movie runs without judder.

I left a comment over on the other issue (jellyfin/jellyfin#8436).

WebOS Browser on my OLED C7 is reporting as Chrome 38, which isn't great for compatibility with more advanced effects, but maybe there's a better way to force hardware acceleration on the browser side rather than manually inserting a webkit-transform call into the CSS.
