Thanks.
I try to compile ffmpeg from source, but failed. Default ffmpeg package in my Ubuntu 10.10 doesn't include AMR encoder. And, I heard ffmpeg can't convert some formats' materials but mencoder can do it, such as some RMVB, WMV, etc..

So, I want to know: is it possible to convert this AVI file to 3GP file just with Mencoder? Does it need some special parameters more than I did?
