Hallo > Top output of the 3 running mpeg2enc with mjpegtools 1.6.1.92 on the > Dual Athlon MP 2100+. That's with -M3. Top usage is 2% and the decoder > is only about 10% intermittent.

Get some frames (100-1000) as yuv format. I gues that should be possible even with transcode. ;) (I do not use transcode so I can't help, or get the test streams on mjpeg.sf.net)
And do afterwards something like that: cat stream.yuv | mpeg2enc -f8 -M 0-3 -o test.m2v or lav2yuv stream.avi | mpeg2enc -f 8 -M 0-3 -o test.m2v So you can be soure that nothing else makes any troubels. And check thant how it is going. That should not take to long. Than you can add the options you used, to see if anything there causes the probelm of non increasing framerate. > > I use the 2.6.0-test8 kernel.

My brain had given up the time I started my computer that evening ;) But I'm not really knowing why the situation is that bad. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
