Apple has announced this week at WWDC2017 support for the High Efficiency Image Format (HEIF) (see video here). HEIF is a new image format defined within MPEG, by companies such as Apple, Nokia, Canon, … and by the GPAC team and Telecom ParisTech. So, the GPAC tools are already capable of producing HEIF images. This post provides instructions to do so.
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).
GPAC 0.7.0
A new release of GPAC is out (0.7.0), check it out ! New features, many fixes and improvements, see the changelog.
Also note that you can meet us at NAB in Las Vegas in two weeks and at EBU Broadcast Thinking. The focus is on low latency MPEG-DASH. Don’t hesitate to contact us!
