Days of Future Past takes advantage of an optimization model and HTTP/3 features, including (i) stream multiplexing, and (ii) request cancellation. In this paper, we propose Days of Future Past, an optimization-based Adaptive...
Read MoreIn this paper, we propose a light-weight transcoding at the edge method for live applications, LwTE-Live, to decrease the band-width utilization and the overall live streaming cost. The increased number of users demanding high...
Read MoreBy securing each link in the supply chain in this manner, we can make it impractical for scammers to impersonate legitimate parties, remove the financial incentive to generate IVT, and increase buyer confidence in the validity...
Read MoreOne use case is to pull the HLS from a VOD2Live engine and push to a just-in-time origin packager such as AWS MediaPackage. const playlist: IPlaylistEntry[] = await createPlaylistFromMRSS(new...
Read MoreAdaptive bitrate (ABR) algorithms of players responsible for selecting the quality of the videos face critical challenges in providing a high Quality of Experience (QoE) for end users. Additionally, end users may have different...
Read MoreThis release is a major release, with numerous API changes, a few new features, and because we hope to have this one as LTS. So, in FFmpeg 5.0, a huge patchset removing all those deprecated APIs was merged last April.
Read MoreIn this paper, we leverage the capability of Software-Define Networking (SDN), Network Function Virtualization (NFV), and edge computing to introduce a CDN-Aware QoE Optimization in SDN-Assisted Adaptive Video Streaming...
Read MoreAbstract: Mobile networks equipped with edge computing nodes enable access to information that can be leveraged to assist client-based adaptive bitrate (ABR) algorithms in making better adaptation decisions to improve both...
Read MoreWhen a user wants to consume a service, the CDN routing system will deliver the “best” node where the content is likely already cached and closer to the client . git checkout 1.0.0 # going back to specific...
Read Moreipp.cfg – the main config file which specifies GOP structure (in our case IPPPP), number of references, mode of motion estimation, deblock filter parameters, switching such tools as PCM and AMP. In a scalable solution a video...
Read MoreThe proposed architecture aims to jointly optimize video quality and latency for a better user experience and fairness. A Distributed Delivery Architecture for User Generated Content Live Streaming over HTTP
Read MoreWhen MPEG-4 Advanced Video Coding (AVC) was developed, the company running the MPEG-2 patent pool was the natural candidate to run the patent pool for the new standards. When MPEG-H High Efficiency Video Coding (HEVC) was...
Read MoreThis article targets video coding improvements for both individual blocks of the hybrid video encoder and jointly across multiple blocks including end-to-end approaches. It reviews various modules in video coding that could benefit from neural networks.
Read MoreAs our platform continues to grow and different scenarios and issues can disrupt the workloads, Pensive has to be proactive in detecting broad problems at the platform level in real-time and diagnosing the impact across the...
Read MoreData scientists in these roles apply the scientific method to improve the Netflix experience for current and future members, and are involved in the whole life cycle of experimentation: data exploration and ideation; designing...
Read MoreThe company aims to reduce operating costs for online streaming and on-demand video applications by dispersing transcoding work to all participating computers on its network. Livepeer, a decentralized video streaming network...
Read MoreThese new presets allow for even higher levels of performance and the ability to handle more AV1 encodes concurrently on servers. At preset level 8, the Xeon Platinum 8380 2P server could encode a 4K stream at 95 FPS.
Read MoreTo optimize the QoE — the quality of experience — for our viewers, the goals for the ABR algorithm are conflicting: we’d like to stream the highest quality possible, but downloading a segment size exceeding the throughput can...
Read MoreOriginally code-named Project Orange, “Elephants Dream” quickly made waves among animation enthusiasts and the open-source crowd when it was released under a permissive Creative Commons license in 2006. But beyond...
Read MoreNow that we have transcoded our video streams with the expected format, it’s possible to generate the fragmented version of our mp4 files with the commands : This low quality audio file, as well as the original version,...
Read MoreDespite the slow uptake of edge computing in the media and entertainment industry, it’s clear that edge computing will drive innovations that will help broadcasters reimagine the viewing experience by overcoming the challenge of...
Read MoreIn the image above we have a comparison of the bitrate ladders and VMAF objective quality scores for H.264/AVC, VP9, H.265/HEVC, and AV1 encoding (2-pass) of the same video. In addition, 22% of those same developers indicated...
Read More(AWS) and Gravity Media, the global provider of live broadcast facilities and production services, collaborated with leading manufacturers to undertake a large scale virtualised, AWS-based, live broadcast production Proof of...
Read MoreThe network load balancer forwards requests using a Round Robin algorithm, to multiple AWS EC2 instances we call “USP Origin”. With Consistent Hashing, we can send all requests for the same video to the same cache...
Read MoreThis e-book will explore the challenges of delivering outstanding video-audio quality on every screen, offering guidance on the steps OTT service providers and broadcasters must take to guarantee a high QoE. OTT uses the...
