Blocking the main thread

[Goule]

Hello,

Thanks for this library.
I'm trying to make a video with multiple images. But when it come to generate the video, my application freeze. In fact it freeze before unlock and print progress.
Is there any way to do it without blocking the UI ?

Thanks

I tried to pass the generate function into the background queue and it's now ok. But it make a lot of time before start the job and passing to the progress handler... For a video of 3 sec with 200 images I need to wait 2 min before saw progress print start in my console. Is that normal ?
Thanks
