Hi there,

yesterday I asked for help to Luis López Fernández about kurento
development, and, being me part of a FIWARE acceleration program (company
sofasession), he suggested me to contact FIWARE helpdesk directly.
It's about developing and installing a new kurento module (not filter).
All the details are in the forwarded email.

Hope to hear from you soon,
Thanks,
