This is flvlib, a library for manipulating, parsing and verifying FLV files. It also includes two example scripts, debug-flv and index-flv, which demonstrate the possible applications of the library. If you got the source tarball, you can run the automated test suite and install the library with: $ tar xjf flvlib-x.x.x.tar.bz2 $ cd flvlib-x.x.x $ python setup.py test $ sudo python setup.py install After that you can debug FLV files with: $ debug-flv file.flv and index them with: $ index-flv -U file.flv Try: $ debug-flv --help $ index-flv --help for more available parameters.
