as far as I know, mencoder isn't able to use both cores of a modern
Dual Core CPU like an AMD64 X2 since it is single threaded.
What I know for sure is, that only 50% load is on my CPU, when
mencoder is working on a video. Or in other words: The encoding
process will take twice the time....
Since I am doing two-pass-encoding, I had an idea which may be
completly nonsens (or not...I dont know the internals of the encoding
Would this script (or simmiliar) work:
mencoder ...... -o /dev/null .... -vf pass=1 <infile>;
mencoder ...... -o <outfile> .... -vf pass=1 <infile>;
...starting the second process to utilize the second core with a
delay to not to get in collsion with the "result stream" of the
Only an idea !
Would something like that work ?
