Is there any other way to increase the conversion speed of the JP2 from the below command.

"ffmpeg.exe -f image2 -threads 2 -i C:\Users\unameit\Desktop\dpx\DPX_%4d.dpx -c:v libopenjpeg -pix_fmt gbrp -strict -2 C:\Users\unameit\Desktop\dpx\cnv\jp_cmd_%4d.jp2"

I know the "libopenjepeg" is very slow

During the conversion I could able to see the CPU is utilized only 20%, and it is using only two core of the CPU. Is there any command to utilize all the core and full CPU, I hope if the conversion uses all the available core and the CPU capacity the conversion time will reduce.
