Comment (by ralambda):
It works if `-threads` less than or equal to '''32''' on the 20 core
system It fails if `-threads` is greater than '''32'''.
It's the same error when it fails when the -threads option is added:
`[dnxhd @ 0x319ec80] too many threads`
'''Works:'''
{{{
/ffmpeg -v 9 -loglevel 99 -y -r 23.976 -i input_file.mp4 -threads 32 -c:v
dnxhd -b:v 36M -pix_fmt:v yuv422p -s:v 1920x1080 -an output_file.mxf
}}}
'''Fails:'''
{{{
/ffmpeg -v 9 -loglevel 99 -y -r 23.976 -i input_file.mp4 -threads 33 -c:v
dnxhd -b:v 36M -pix_fmt:v yuv422p -s:v 1920x1080 -an output_file.mxf
}}}
