Installation-free

In order to provide installation-free package, we provide binary executables for Linux (32 and 64bits), Windows, and Mac OS X. The binaries files were generated with Pyinstaller (version 1.5RC1).

If you have Python installed, you can directly run the start_crawl.py script at root or the pytomo script in bin directory.

External Resources

We based the lib_youtube_download on YouTube Download script: we simplified it at most and include only the classes we needed (and only YouTube video retrieval).

The dns module is taken from the DNS Python Package: we just modified rdata so that Pyinstaller include all needed modules.

The extraction of metadata out of video files is an adaptation of Kaa Metadata Python Package: it has been modified in order to be independent of Kaa-base (thus pure Python and portable).
