You even can assign a core to a task, however, multi-threading is known
to cause issues for real-time audio. You still can disable
multi-threading and assign cores to tasks. To me it's just hearsay, my
CPU is just an aged dual-core, without multi-threading, but I tested
the following.

Regarding video codecs an approach is to enable video acceleration
instead of using software decoding. It's more or less unsupported (no
Linux browser does provide it, even not when using special add-ons),
but the few times it is supported (at least one media player does), it
makes a very big difference regarding usage of resources.
