With the introduction of the new mpv player in the iOS and tvOS Plex app there’s now a reason for me to generate preview thumbnails for all the videos in my library. I’ve set my server to start generating thumbnails as a scheduled task, but there’s a lot of videos in my library and I’m curious how far through this process I am.
So is there any way for me to get a count of the videos in my library that still need thumbnails generated for them? It’d also be nice if I could get a count of the videos that do have thumbnails, in order to know what percentage of them are done.
I’m guessing this requires making a query directly to my Plex library’s sqlite database, but if there’s a simpler way that’d be even better.
I gave ExportTools a try and it doesn’t really seem to be that useful for what I want to do. Exporting the parts of my library produces some unwieldy and huge spreadsheets. Also I’m not sure what the values in Part Indexed represent.
Is there something else I can do with ExportTools that I’m missing? Also I still think there’s a query I can make to Plex’s database that’ll do what I want more directly. I’m just not sure what it is. (e.g. Which field in which table has what I want?)
