This is a simple flv format parser, which can output the info about audio tag, video tag and scriptdata tag.
All the flv files to test are located in the folder "res", and all the source codes are located in the "src" folder.
Execute the "start_build.sh", then go to the folder "build", execute "make" command, then you can get one executable file named "flv_parser".
./flv_parser ../res/sample1.flv
