That can happen if the load is split bad ord if you have a to slow network. The distributes encoding with several machines workes better when you have only machines below 1GHz CPU frequency. (The slower the besser ;) ) On a really fast machine that does not help much more. Sometimes the network might become the bottleneck.
>>> I used this cmd to encode a movie: >>> >>> lav2yuv test.liste | yuvcorrect -Y CONFORM | y4mshift -n -4 | >>> y4mscaler -v0 -O sar=59:54 -O size=720x576 | yuvdeinterlace | >>> yuvmedianfilter | yuvdenoise -m 2,2,2 -g 64,255,255 -t 3,3,3 | >>> y4munsharp | mpeg2enc -f8 -D 10 -E -10 -q 5 -b 7800 -M 2 -K tmpgenc >>> -4 1 -2 1 -o test.m2v >>> When it´s running i still have around 30% "free" cpu time, also when >>> i do -M 3 instead of -M 2 it doesn´t do much difference. >> The -M does not help much. It is more important that you add somewhere >> in the encoding command one time the buffer or bfr program. I usually >> add it before mpeg2enc. When Using buffer I use 2048 buffers of 10k. >> I use buffer always. >> >> So the command lookes like that: >> lav2yuv ... | .... | buffer -b 2048 | mpeg2enc ... > Also with buffer -b 2048 i still have rest of cpu time about 30-35% There a 2nd buffer might help after yuvmedinafilter. It won't help if yuvmedinafillter need 100% of one cpu and all the other programms need together only 70% of the 2nd cpu. Who much CPU time do all the programms use ? Could you please post a screenshot of top when you encode the movie. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------------------------- Using Tomcat but need to do more?
