[Bug] MKV Performance-Bug

[the-hotmann]

Current Behavior

I have used MakeMKV for quite a while in the dockerized version, but now since two versions, between:

• v24.11.1
  and
• v24.07.1

so since v24.11.1 there is a hefty performance bug, when you want to re-mux .mkv files (4K, DV & HDR) and want to process them.
As soon as I switch back to version v24.07.1 all these performance problems are gone and throughput is again up at about 600MB/s.

This is a problem introduced with MakeMKV 1.17.8.
