[Avidemux-users] v2.8.1 encoding at half speed

[Jodi W. <jo...@jo...>]

Hi,

I can't seem to get onto your forum, doesn't like my email. Just thought
I'd report that I'm seeing a lot of slowdown with encoding in this version
on my system, like half the speed of v2.8.0. It seems to be file operations
too, I can see slowdown in the file loading too. Info dump below.

Kind regards,

Jodi.
