Is there a program in the pipeline that uses 100% of one CPU ?
Did you run the pipeline with the time program ? So you know how much time each program consumes (should work): time ./rfbproxy -x ../../files/q3.fbs | time ppmtoy4m -S 420jpeg | \ time mpeg2enc -f 3 ... You might gain some speed by using a buffer program like bfr: http://www.glines.org/software/bfr You use it in a way like that: ./rfbproxy -x ../../files/q3.fbs | ppmtoy4m -S 420jpeg | \ bfr -b 64M | mpeg2enc ... auf hoffentlich bald, Berni the Chaos of Woodquarter Email: shadowl...@utanet.at www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------------------------------ Come build with us!
