Raspberry Pi (Raspberry Pi) sends a video stream to the PC using the socket

Install boost

sudo apt-get install Libboost1.50-all

Test boost

1.cpp

#include <string> #include <boost/regex.hpp> int main () {         std::string text ("A fat cat sat on the mat"); 
   
    boost::regex Re ("\\w+");         Boost::sregex_token_iterator I (Text.begin (), Text.end (), re, 0);        Boost::sregex_token_iterator end;         for (; I! = end; ++i) {                std::cout << *i << ';        }         Std::cout << Std::endl;         return 0; }
