How to print motion vectors from a mp4 video

[hazlorealidad]

I have searched on internet to print motion vectors and have found
that

Mplayer will display them like this:
mplayer -lavdopts vismv=1 -vo x11 motion_vector_video.avi

Also a c program that prints them from this page:

I needed to extract motion vectors from videos...
Need to have ffmpeg, libavcodec-dev, libavformat-dev installed. Tested
on Linux Mint 9.

gcc -std=c99 -o motion_vector -I/usr/include motion_vector.c -
lavformat -lavcodec

(motion_vector.c can be downloaded from the link above)


Also another project http://jmu.sourceforge.net/ appears to do this.

In the documents they state:
As before, if you require to extract motion, it is required to
activate motion debug option:
vsr.setDebugMV(true);

However I wanted to do this with xuggler as it seems that the project
is more advanced.

Can anyone tell me if its possible and if so a code fragment would be
great.

Thanks

I am still interested in the possibility of getting the motion vector
information using xuggler, can anyone tell me if it is possible, and
how to do it?
