grilo: integration of multimedia contents in applications made easy (fosdem 2011)
DESCRIPTION
By Joaquim Rocha. YouTube, Shoutcast, Last.fm or Jamendo are just some examples of the number of existing services offering media content nowadays. Users are now getting used to having these services available also from their usual applications. Unfortunately, to integrating these services in an application developers need to learn new technologies, with different APIs and protocols which means they end up writing specific solutions and replicating a lot of work. Grilo was created to solve this problem by providing a framework that abstracts the way to access media services and hides their specifications from developers. This minimizes the effort to integrate such services in applications letting the developers focus on their applications rather than in the services. In this talk, I will introduce Grilo, the problem it solves, the services it integrates so far, and give an overview of how to use Grilo in applications. If time allows, I will also show how a Grilo plugin looks like.TRANSCRIPT

Challenges inMedia Integration:
* Homogeneous, integrated UX* Easy to use
* Service scalability* Decrease development and
maintenance effort

Our proposal:* Platform level solution for accessing media contents
*Stop reinventing the wheel, start reusing code
* Stop splitting efforts, collaborate!
Joaquim Rocha (Igalia) · OCRFeeder · FOSDEM 2010
The benefits:* Reduce and share maintenance
effort* Faster development
* Scalability* Seamless support for more
services

Meet Grilo!
Joaquim Rocha (Igalia) · OCRFeeder · FOSDEM 2010
Overview:* Framework to access easily to multimedia content
* Provides a single API to access media content* Hides differences in media services (APIs,
protocols, technologies, limitations, ...)* Developers write their solution once and it works
with all services supported by Grilo
