VLC Stutters on Manjaro?

Postby CompSciSarah » 13 Dec 2020 00:54

VLC Stutters When Seeking?

My VLC stutters (even for this humble 480p reading of Arthur C Clarke’s A Walk in the Dark).

This is surprising to me given my system specs (the file is local, not network) and is on my NVME hard drive.

I would not expect such seeking issues, which are only compounded when I view my 1080p school material.

Here is a video of it in action at various speeds: https://youtu.be/Gf0ixc14Ulw 1

How can I resolve this?

VLC Version: 3.0.11.1-6 (Installed from Manjaro official repository)

VLC Options:

Try using

Code: Select all

--input-fast-seek
to turn on fast seeking, which will cost seeking precision.
Is your problem exclusive to VLC?

This can be caused by an unstable audio clock or unstable real-time clock (well, anything that makes both clock not correlate well).
