To get the plain mpeg4 video stream I had to remove Cellvisions additional header structure.
The header seems to be always 40 bytes long, and index 24-27 are the size of the following video data.
In java it look like this:

byte[] hdr = new byte[HEADERSIZE];
int r = in.read(hdr);
//convert 4 bytes to an int
int ret = (hdr[27]& 0xFF)<< 24 | (hdr[26]& 0xFF) << 16 | (hdr[25]& 0xFF) << 8 | (hdr[24]& 0xFF);


I’ll provide a sample program later (check downloads).
