I think you misunderstood what Grilo is and is not.

Grilo is a framework to provide media, it is not a media player.

Grilo’s plugins provide you with media sources from various services, for example, Grilo can tell you which media (music, videos, pictures) you have on your hard-drive, or you can browse or search them on YouTube and Vimeo, you can also search for photos on Flickr.

Grilo won’t play the content for you. You have to handle that detail yourself, so, the idea is that if you want to build a media player that plays videos and music from your HD or YouTube, you can use Grilo to provide you the media and play that media using GStreamer, for example.

I hope you got it now

Best regards,

Wouldn’t it be better to extend MPD instead of creating YAMD (Yet Another Media Daemon)?
