OK, I guess I should have read the HTML documentation not just the
manpage. Any specific recommendations ?
This seems better :
$ mencoder -tv input=1:norm=NTSC:driver=v4l2 \
-oac mp3lame -lameopts cbr:br=64 -ovc lavc \
-lavcopts vcodec=mpeg4:vbitrate=900 -vf pp=lb,crop=640:464:0:4 \
-o foo.avi tv://
Is there anything to be gained by capturing in MJPEG or raw
format then doing a 2-pass MPEG conversion offline ?
