Hi,
This is my line. I'm no video pro, just a home recorder, so please don't be
too excited. This line is result of lots of trials and errors. There's
likely a lot to be optimized here.

mencoder -tv
driver=v4l2:fps=29.97:adevice=hw.0:alsa:input=1:outfmt=bgr24:mjpeg:decimation=1:quality=100:audiorate=32000:norm=NTSC:width=704:height=480
-ovc lavc -lavcopts vcodec=mjpeg:vbitrate=2000:mbd=1 -vf pp=lb -oac twolame
-o teste.avi tv:///3
