SOLVED: Regenerate trickplay images

[theolaa]

Just as a FYI, with v10.9.3, I assume you'll need to keep the "Extract trickplay images during the library scan" option enabled in the library settings for the manual rescan with "replace all images" to actually replace the trickplay files.

With v10.9.3, I replaced all metadata for a video and chose the "replace all images" option too. Then according to my logs, no trickplay file was regenerated. My system CPU didn't increase too, so I know nothing happened.
I have the extract trickplay during a scan option disabled, so only the scheduled task will handle them.

So if you want to force a trickplay regeneration, enable that option if you haven't yet.

Brilliant, that's exactly what I needed. Thanks!
