Dr. Christian Feldmann is working on next generation video coding technologies such as AV1 and VVC. He is applying his doctoral degree (PhD) in video compression technologies to build and improve large scalable video solutions. Christian participates in the standardization activities of the Alliance for Open Media (AOMedia) as well as the Moving Picture Experts Group (MPEG).
At IBC 2023 the Fraunhofer HHI, Spin Digital and Bitmovin are presenting a paper on the practical application of a new feature that was introduced in VVC: Open-GOP resolution switching. In this blog post I want to explain what open-GOP (Group of Pictures) prediction is, what the benefits are and why with VVC open-GOP prediction…
State of VVC Video Codec So it’s happening. After their previous work on h.264/AVC and h.265/HEVC, the ITU-T Video Coding Experts Group (VCEG) and ISO Moving Picture Experts Group (MPEG) have again joined forces to create another video codec named Versatile Video Coding (VVC). The first goal for the VVC Video Codec was to significantly…
For an APAC live event, our video coding engineer Christian Feldmann compared the HEVC (H.265) vs VP9. During the session, we discussed the fundamental differences between the two “modern codecs” and tied it off with an early analysis of each codec’s performance. These results were obtained using the open-source encoders libvpx-vp9, x264, and x265. This…
This scientific evaluation puts AV1 to the test against industry standard codecs and shows that AV1 is able to outperform VP9 and even HEVC by up to 40% Introduction For practical Over-the-top (OTT) streaming applications it is mostly necessary to supply streams using multiple different video codec standards in order to stream to a wide…
What is VVC? Versatile Video Coding (VVC) is the most recent international video coding standard which was finalized in July of 2020. It is the successor to High-Efficiency Video Coding (HEVC) as it was also developed jointly by the ITU-T and ISO/IEC. So what is really new in VVC? Is this a real revolution when…
Now that AV1 has entered its final stage of development and is getting close to finalizing its features, it’s a perfect time to take a closer look at what’s in store for the future of video streaming. With Apple announcing their decision to join the Alliance for Open Media in January, practically all major tech…
