#10533 open defect

encoding to libaom-av1 is so slow it appears to hang

Description

Downloaded several windows builds including the lastest nightly build. On a fairly modern machine in Windows 11 using the command
ffmpeg -v 9 -loglevel 99 -f lavfi -i testsrc=size=hd1080:duration=5 -pix_fmt yuv420p -vcodec libaom-av1 test.mp4
I get about 1 fps encoding speed, whereas in comparison encoding to libsvtav1 will give me 100 fps. The resulting video file seems to be allright.

Tried on another machine in Windows 10 with comparable result.

Still the case, 2 fps here due to me using Arrow Lake Lion Cove.
