I assume you meant luvcview. It works for monitoring, but I can't
figure out how to record properly...
1) It outputs a raw stream file (named "stream.raw") which mplayer can't
figure out how to play.
2) How do I get it to record audio too?
I wouldn't mind transcoding the raw output, if I could get sound in
there. ffmpeg can record mpeg4 video plus mp3 sound. The video has
blocky artifacts when there's motion on the screen. I tried ffmpeg with
x264 codec, but the cpu is simply not up to it. I used cpufreq-utils to
push both cores to their max speed (1.3 ghz) but it didn't help.
