They didn't enable multi-core encoding using this +library until version 1.2.0. Since you can't get that in a package, +you can build it from source easily. Since the xvid codec (this lib) +is used by mencoder by rip_dvd in all of its xvid profiles (the default), +you can speed up the encode process quite a bit if you enable multi-cores. +Follow these instructions to enable the xvid encoding to use multi-cores: + +> wget http://downloads.xvid.org/downloads/xvidcore-1.2.1.tar.gz +> gunzip xvidcore-1.2.1.tar.gz +> tar xvf xvidcore-1.2.1.tar.gz +> cd xvidcore/build/generic +> ./configure --prefix=/usr +> make +> sudo make instal +> cd /usr/lib +> rm libxvidcore.so.4 +> ln -s libxvidcore.so.4.2 libxvidcore.so.4 + +After you do these steps, when rip_dvd is running using any xvid profile, +you will note with 'top' that the mencoder process is using > 100% of your CPU. + ---------------------------------------------- CONFIGURATION ----------------------------------------------
