The CPU limit argument of Handbrakes seems to have no effect in Windows. One way to get around this is to start Handbrake with the built-in “start” command with the affinity argument.
start /wait /affinity 33 "" "C:\Program Files (x86)\MC-TVConverter\tools\handbrake\HandBrakeCLI.exe" -i "K:\example.mkv" -e x264 -q 20.0 -d -a 1 -E faac -B 128 -6 dpl2 -R Auto -D 0.0 -f mp4 -C 2 -X 720 -m -x cabac=0:ref=2:me=umh:bframes=0:weightp=0:subme=6:8x8dct=0:trellis=0 -o "K:\example.mp4"
Here, I use a batch to encode files numbered sequentially.
@echo on set count=10 :run set /a filenumber=%count% if %count% lss 10 set filenumber=0%count% start /wait /affinity 33 "" "C:\Program Files (x86)\MC-TVConverter\tools\handbrake\HandBrakeCLI.exe" -i "K:\exapmple%filenumber%.mkv" -e x264 -q 20.0 -d -a 1 -E faac -B 128 -6 dpl2 -R Auto -D 0.0 -f mp4 -C 2 -X 720 -m -x cabac=0:ref=2:me=umh:bframes=0:weightp=0:subme=6:8x8dct=0:trellis=0 -o "K:\example%filenumber%.mp4" set /a count+=1 if %count% leq 13 goto :run
Affinity takes an hex input. For example, forcing only the use of cores 0,1,4,5 requires an affinity of 33 (110011).
