[packman] ffmpeg and libx264 error

[oldcpu]

What happens if add after libx264 the parameter " -vpre hq " ..... ie 
something like:

ffmpeg -y -i Warriors_of_the_net_CZ-MPEG1_Web_PAL.mpg -vcodec libx264 -vpre hq -acodec copy output.mkv -threads 0


I find I need the " -vpre hq"  or " -vpre max "  or  " -vpre <option> "
with some applicable option every time I use ffmpeg with libx264 to encode.
