Non-blocking postprocessor.

Let's say, I have a list of pixiv ugoria and get it passed to: gallery-dl --ugoira-conv-lossless. The download halts as recent downloaded artwork getting processed into video. Once done, download continues.

Can this be speed up? I'm thinking a task or threading, specifically for post-process ugoria AND likely other similar case.

It fast, BUT there is a chance when the post-process is time consuming. I mean, like really time consuming, encoding video from set of images is time consuming, sometimes.

This issues is not related to parallel downloading, but parallel processing.
