Encoder thread count?

[Moehammered]

The thread count is unspecified and ffmpeg uses the default value. I'm not sure how many threads ffmpeg decides when it defaults.

That said, the ffmpeg encoder shouldn't peg the cpu as it captures the desktop. However it should show more cpu usage if you set the preset to a relatively demanding setting.

When you try preset on very slow and quality control factor to 0 is the cpu usage higher than ultra fast and qcf of 20?

Yeah, it does, a bit, and looking at ffmpeg in process manager, it says it's using 64 threads. I did a search, and ffmpeg's default is 1.5x your CPU thread count for frame threads, 1x for sliced threads.

Thanks for looking that up and sharing it. It's good to know and might be worth experimenting with sliced frames as an option. I'll look into that as an extra down the line.

Did you have any other issue related to encoder thread count? Or was that the only thing? If so please close the issue.
