The existing tool youtube_uploader already parses metadata from files using mutagen:

    https://github.com/Freeseer/freeseer/tree/master/src/freeseer/tools/youtube_uploader

Why do we need scrapemark? is it better than mutagen? Does it provide functions that the existing code does not?

Unless there's a really good reason that we need scrapemark over mutagen, I would prefer we stick with a library we are already using rather then introducing even more libraries, this increases the complexity of our install process unnecessarily. If we are introducing additional libraries to Freeseer I think we need to have this discussed on the mailing list.
