Full Version: AV1 - how to enable mulithread encoding?

Hello

I'm trying to play around with the AV1 encoder but it always uses only one CPU core. This makes encoding process very slow.
I've changed BASE -> MISC -> THREADS but it has no effect. What's needs to be change to enable multithread encoding?
Encoder related threading options are always inside the encoder tab.
For av1 there are three encoders in Hybrid, each with their own settings:
  • aomenc ('aomenc->Base->Miscelleaneous->Threads' + number of tiles and resolution also influences threading)
  • rav1e (rav1e->Base->Threads)
  • SVT-AV1 (all under 'SVT-AV1->Misc->Threading&Co')

Cu Selur

Ps.: iirc all three encoders are not that tuned for multithreading in their current development state.
