Trickplay 4k Image Generation not working

[AudioVisualAndy]

My scheduled task is not generating Trickplay images for 4k content. The lower resolution Trickplay images get generated without a problem.

I searched for my issue and came across other users having the same problem, but this was always in the context of the (previous) Trickplay plugin, and not the integrated Trickplay capability. From reading the problem description, there is an issue with transcoding the 4k image to a Trickplay image and the process (probably) times out for 4k content. For the plugin, there was a setting to increase the timeout setting to allow for the process to complete, but I cannot find an analogous setting in Jellyfin now that Trickplay is integrated.

I am running 10.10.3 in Docker on a Synology NAS, so no GPU or hardware acceleration is available.

I also searched Github and could not find an issue. Am I missing something? Is there a preferred solution?

Can you share your jellyfin logs via privatebin.net? And screenshots of how you have trickplay configured? Dashboard > Playback > Trickplay.

Here is the log: https://privatebin.net/?cb483abff5e94dfc...y36ErZ8PxA
Here is my config: https://privatebin.net/?ef14a961e4d438c9...ut3E18RZFE

I didn't change the default expiration time of one day. What should I choose in the future?

Your CPU is too slow to generate high resolution pictures. You need to increase the ImageExtractionTimeoutMs to something larger. like 30 seconds (30000). The default is 10second and it looks like your cpu cannot do that in 10s. You can also enable the Only from keyframe option as that option can provide significant speedup(up to 100x depending on your system)

Where is the 'ImageExtractionTimeoutMs' setting located?

[TheDreadPirate]

It is a parameter in system.xml.

I can't tell if this is a bare metal linux or docker install.

/etc/jellyfin/system.xml for a bare metal linux install.
/config/config/system.xml for a docker install.

I just set that setting to 30000, it was 0. I kicked off the Generate Trickplay Images Scheduled Task. I will let you know if it works.

[AudioVisualAndy]

I am still seeing failures. I set it to 30000 ms, and bounced the container in case the settings did not dynamically update.

Did you ever enable "Only generate images from key frames" as gnattu suggested? That should massively speed up trickplay creation.

[AudioVisualAndy]

No, I did not. I understand that this would require less images to be generated, but I should still be able to configure resources to enable this to task to finish. The first time I ran the Trickplay Task, it took 22 days to complete. I am fine with that performance as long as it completes.

Is there a way for me to devote more resources to this task? Will just increasing the timeout, e.g. 1,000,000 ms, get the task to complete? Is this timeout for every single image that is being generated, or are the images batched, etc.?
