The documentation for install is not clear at all, and also there is a lot of duplicate files due to composer (vendor/sebastian, /vendor/symfony, etc..) into the libraries folder.
Why not implement Brightcove module with the Composer Manager module so we will be able to:
1/ Install it with Drush in one line
2/ Avoid install problems and troubleshoot
3/ Avoid hundreds of duplicate files
4/ Manage easily the update for security issues by Composer Manager
