From http://www.videolan.org/developers/vlc-branch/NEWS

Changes between 0.8.6i and 0.9.0:
...
* Croping and padding in transcode are now done using the croppadd video
filter. For example:
transcode{vcodec=mp2v,vfilter=croppadd{cropttop=20,cropbottom=30,paddleft=100}}

OK. thanks.
I try new command as below
#transcode{vcodec=h264,vb=1800,scale=1,width=640,height=480,vfilter=croppadd{cropttop=0,cropbottom=0,cropleft=0,cropright=0},acodec=mp4a,ab=128,channels=2,samplerate=44100}:std{access=http,mux=ts,dst=0.0.0.0:8080}

the test result update:
croptop does not work. others work. and looks like vfilter=canvas{width=640,height=480} does not work but "width=,height=" is OK.
such as
:sout=#transcode{vcodec=h264,vb=1800,scale=1,width=640,height=480,vfilter=croppadd{cropttop=10,cropbottom=0,cropleft=0,cropright=0},acodec=mp4a,ab=128,channels=2,samplerate=44100}:std{access=http,mux=ts,dst=0.0.0.0:8080}

client show 640X480
and cropttop=10,cropbottom=10,cropleft=10,cropright=10
client display 620X470.
other combination: 0,0,10,0;0,0,0,10,0,10,0,0 all are OK. only 10,0,0,0 is not OK.

BTW, the value of croped should not be odd. otherwise, vlc show ffmpeg lib error.

Not sure if you figured it out, and I know this post is quite old now, but for the sake of helping people looking for the answer, you spelt croptop with two t's by mistake "cropttop".
