APNG thumbnails

[unreadablewxy]

• Current thumbnailer snaps the first frame visible. This is not ideal for non-images that frequently starts with solid colors.
• We can't just transcode a hour long APNG if the source is that long.
• Perhaps a configurable strategy? possibly +X seconds from first contrast change, or when histogram drastically changes?

Hello. Check out this project, how he handles the "evading".

Some snippets from there, which could help:

I like that script so much, it's robust and clever for the job. It uses mplayer and ffmpeg hand in hand (and other needed tools too). But sadly it's in bash. Plus: I have zero interest in the pretty collages, I just need the clever sequence-thumb-taking. In the past I trimmed the whole script down, but that's a lot of work, so I still look out for other workflows. Which brought me HERE !! I have extreme high hopes for fs-curator, because it looks like 99,9 % of exactly what I try to do for years.

I hope you can get some inspiration from VCS.

I mean, there are even more nifty things to get a better thumbs sequence. Recently I saw a project which even uses opencv to detect scene cuts. But for my "taste" that is way to slow, if you need to index/scan hundereds of movies.

I had a read of their docs & licensing info. I understand the behavior they're going for and it should be doable.

Can't use or read VCS code though due to licensing incompatibility. So please excuse me snipping that image down to a link.

Out of curiosity @KoolKeith, could you provide a bit more detail on what you want done to your files? From the moment they're placed into a hopper to when they're placed into a store
