Trick Play Generation issues

[smmx]

Hello,

I'm new to Jellyfin and I'm trying to get my library's Chapter, trickplay, subtitles, etc. all set up.

I'm trying to run the trickplay extract process and it's just simply not working. I have it running in a Proxmox LXC (created by proxmox helper scripts). Version 10.9.6

The logs initially showed the following:

Code:

Now when I re-run I only get the following:

Code:

I've tried with and without hardware decoding on. Any suggestions on what I can try to fix this?

Thank you

A) is trickplay enabled in the library settings
B) if it is already enabled, do you also have trickplay generation on library scan enabled?

a) Yes - on all libraries I have
b) No

Pick a show or movie and refresh metadata, select "replace all metadata" and check replace images. Jellyfin will attempt to recreate the trickplays and re-extract chapter images.

How do the logs look when you do this?

I may have had a permissions issue with the file mount, along with needing to increase my disk space slightly.

I see trick play in the web client but I’m not seeing trick playing in Swiftfin or the Jellyfin android app.

It sounds like this feature is not yet available in these apps. If that’s the case I don’t think I have any issues with Jellyfin itself, rather I need patience while the apps get support.

AFAIK, Swiftfin definitely doesn't support trickplay. Keep in mind that Swiftfin is still a beta/not feature complete. But it has seen a lot of development recently.

As for Android, I tried Findroid (exo and mpv) and the official app (exo and web) and only the official app with the web player showed the trickplays. But that comes with its own compromises.
