[MEncoder-users] Trying to get mencoder to output DV format

[Dieter]

I can get mencoder to output mpeg4, but I haven't
been able to get mencoder to output DV format video.
Clue needed.  Thanks.

/app/bin/mencoder -tv \          
driver=v4l2:device=/dev/video1:normid=0:chanlist=us-bcast:fps=29.97:\
outfmt=yuy2:width=720:height=480:\
adevice=/dev/dsp:amode=1:forceaudio:audiorate=48000:volume=100 \
-vf expand=720:480 \
 tv://10 \
-of lavf -lavfopts format=dv \
-oac lavc -ovc lavc -lavcopts acodec=pcm_s16le:vcodec=dvvideo \
-o out.dv
