opendds video streaming using opencv

Question

i have a question of this. I am using opendds to stream video using opencv. In opendds i used data type CORBA::OctetSeq data for mat data.

I have successed using tao_idl and opendds_idl to make several files and now i'm trying to make publisher.cpp

Do you know how to put the mat type data to OctetSeq data??

I've tried like this.

... Mat img img = Mat::zeros(480,640, CV_8UC1) cap >> img message.data = img ...

the error says that the operator don't work

if i set message.data = img.data it says that "error: invalid conversion from 'uchar' to 'CORBA::ULong'

please help this project is unit Feb :(
