Hello everybody,

I am trying to create a dvvideo and audio stream inside the dv format,
bug I am unable to get it working, i am getting errors like "[dv @
0xa4755b0]Can't initialize DV format!" I have no idea what goes wrong,
can somebody help me? Does it work on your systems?

example of command used for testing:

mencoder tv:// -tv
driver=v4l2:device=/dev/video0:input=1:norm=PAL-BG:adevice=/dev/dsp1:immediatemode=0:audiorate=48000
- -oac lavc -lavcopts acodec=pcm_s16le -ovc lavc -lavcopts
vcodec=dvvideo:format=422P -of lavf -lavfopts format=dv -o output6.dv

output with the errors:

Writing header...
[dv @ 0xa4755b0]Can't initialize DV format!
Make sure that you supply exactly two streams:
     video: 25fps or 29.97fps, audio: 2ch/48kHz/PCM
     (50Mbps allows an optional second audio stream)
Floating point exception

Any help is really appreciated, what is going wrong here, how can I make
dv containers with mencoder?

I almost forgot I am using version 1:1.0.rc2svn20090311-0.0 from
debian-multimedia.org:
dpkg --status mencoder
Version: 1:1.0.rc2svn20090311-0.0

Thanks in advance,

Best regards,

Jelle de Jong
