Hello- I have a setup right now that allows me to record TV shows on to my system when I want. As hard drive space and CPU power are both in short supply on this setup, I encode with MJPEG as I record, then I later encode it to divx using a two-pass setup. Now... I've run in to a bit of a problem. TV recording works great. I want to record from a video camera, however, playing back some home-movie quality tapes (of track meets, actually). I figured it should work, no problem. I was wrong. My CPU utilization jumped from where it normally sits at 80-85% up to 99% and I started getting one in every five frames dropped. The bitrate jumped from ~8000kbps to over 15,000kbps. The only thing I can think of is either the video camera is just funky (we're using composite connections) or perhaps the shakyness of the video is making it near impossible for the encoder to keep up on this slow (650MHz Duron) processor. What are your thoughts? I can provide the commandline and output for the recordings if you wish. I'd appreciate some input, and maybe a possible solution. :-) Rob

I don't record with mencoder (but with streamer) but maybe this helps you: - Try different quality settings. In streamer my computer keeps up well with 90% quality, using 60-70% of CPU time, but with 95% quality it's too slow. - What is the difference between MJPEG and JPEG? With streamer, MJPEG is *much* slower than JPEG. Can this be chosen in mencoder?
