Hello Selur,
see my post on github:
https://github.com/vapoursynth/vapoursyn...4620507489
let me know, if you can replicate my results (the clip preview will frozen after 100-500 frames).
The havc_test is a simplified version (all the functions regarding colorization and network connections are no-op).
Honestly on my side, in some case, the preview is freezing already on BestSource call.

Is this even related to get_frame ? For me it freezes while using "--info", so this might be a more fundamental issue. (I assume that '--info' doesn't really calls get_frame)

Ah okay, tested just in vsViewer this time.
Give him some time.
a. today is a holiday depending on where you live
b. it's not that this is the only problem in Vapoursynths issue tracker
c. Vapoursynth is a huge project.
=> If he doesn't give an update in a week or so, I would ask further, but not reacting for a few days is something that is normal in my eyes.
