Spring Demos

It’s demo season !

GPAC is powering a 16K 360° video demo at Roland Garros 2017 as part of the Live360TV project:

We are also exhibiting at the Future en Seine event as part of the 4Ever-2 project, where we demonstrate hybrid scalable broadcast broadband with an AVC 1080p 50hz SDR base broadcast enhanced with an SHVC UHD HDR (PQ) layer carried over broadband DASH, check it out !

SHVC decoding is powered by our close friends at openHEVC, broadband/broadcast synchronization is achieved through MPEG-2 TS TEMI.

 

H2B2VS Celtic+ Award

The H2B2VS project has received the excellence award in multimedia for its outstanding work, at the Celtic-Plus Event in Barcelona on 18 May 2017!

During this project, the GPAC team has standardized the MPEG-2 TEMI extensions used for broadcast-brodband synchronization and implemented several demos based on this techno (small tutorial here on how to use GPAC for such demonstrations).

 

Internship: next-generation video streaming analyzer (Paris, France)

GPAC is a Free Software multimedia framework. The project covers different aspects of multimedia, with a focus on multimedia packaging and presentation technologies (graphics, animation, interactivity, VR). We provide popular packagers, streamers and players on http://www.gpac.io.

The GPAC team builds tomorrow multimedia standards. The GPAC team is renowned for its participation in standards (ISO/MPEG, W3C, etc.). GPAC is the reference software for some core multimedia technologies and drives innovative technologies (scalable and interactive video, etc.).

The internship aims at exploring the CMAF standard. CMAF aims at unifying all the existing video streaming formats and is backed by Apple and Microsoft. The role of the intern is to participate in the development of a CMAF validation service.
