[MPlayer-users] MEncoder RTSP Stream Recording

[Steve]

Hi All,
I am using a Panasonic Camera and I am able to use the following
command to Play the RTPS stream:

mplayer rtsp://x.x.x.x/nphMpeg4/nil-640x480 -user xxx -passwd xxx
-cache 8192 -fs -fps 30

Now, I am trying to use MEncoder to record the stream by using the
following command (taking a 30 FPS and turning it into a 5 FPS):

mencoder rtsp://x.x.x.x/nphMpeg4/nil-640x480 –user xxx –passwd xxx
-ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell:v4mv -fps 30 -ofps 5
-nosound -endpos 00:00:30 -o test.

Now I am getting the following message:

So, I can play using MPlayer, but I can not record the stream via MEncoder?

I also tried using:

mplayer rtsp://x.x.x.x/nphMpeg4/nil-640x480 -dumpvideo -dumpfile test.mp4.raw

But that also did not work...
Anyone using similar scenario with Panasonic IP Camera?

Thank you for any help or tips.
Cheers.
