[MEncoder-users] lavc options

[José Antonio Castelbón Fernández]

Hi to everyone

I'm trying to develope a mobile video stream application, and i'm using 
mencoder to encode the videos. The video format is mpeg4, 6-8fps, qcif 
and 40kbs maximun bitrate. My mencoder options are:

-vf scale=176:144 -ofps 8 -nosound -ovc lavc -of rawvideo -lavcopts 
vcodec=mpeg4:vbitrate=40:mbd=1:vrc_eq=1:vstrict=1:trell:dia=-3:cbp:qns=1:v4mv:keyint=250:turbo:vpass=1

-vf scale=176:144 -ofps 8 -nosound -ovc lavc -of rawvideo -lavcopts 
vcodec=mpeg4:vbitrate=40:mbd=1:vrc_eq=1:vstrict=1:trell:dia=-3:cbp:qns=1:v4mv:keyint=250:turbo:vpass=2

With this configuration the final video has a lot of ghosting, i try to 
encode it with less keyint but the motion gets worse. I'm not an expert 
and i guess if you could help me to find the appropiate mencoder options 
to see a decent and well motioned video on the mobile with the streaming.

Cheers,
Jose Antonio
