[MEncoder-users] parameter problem

[Albert Scholtalbers]

Hi There,

I tried to implement some parameters with Mencoder, but I can't seem to get
it to work.
I've used the example here
http://h264.code-shop.com/trac/wiki/Encoding#Mencodermp4creator and removed
the logo creator.
I used this parameters

*input:*
mencoder /home/albert/input.mpg -o /home/albert/output.avi -ovc x264
-x264encopts
bitrate=700:threads=auto:subq=6:partitions=all:8x8dct:me=umh:frameref=5:bframes=3:b_pyramid:weight_b
-vf scale=720:480,harddup -oac faac -faacopts br=56:mpeg=4:object=2 -srate
44100 -ofps 30000/1001

*With output:*
