garlic-player - Open Source SMIL Player for Digital Signage

The garlic-player is a SMIL 3.0 compatible digital signage player.

The goal for the development was to create a most as neccessary SMIL 3.0 compatible and as most as possible platform independent free open source multimedia player to meet the needs of the digital signage industry. The garlic-player has reached now a high level of compatibility and stability. So it is used in many projects and some android hardware solutions.

Digital Signage is a relatively young business and it has a lack of standards. As customer you can easily trapped into a vendor-lock. A public standard like SMIL offers you more independence and security for investment.

The garlic-player can be used offline and online.

Based on SMIL standard it works together with every compatible digital signage software.

You are able to play local and remote (via http) SMIL files with the features described below.
