Here’s the class description; download link below. With the speed of technology today, one of the most important parts of software is adaptability. By taking control of your own encoding and packaging, you can greatly reduce cost and maintain high adaptability and agility to meet your needs now and in the future. When working with…
DetailsMy article, What is VVC, just published on Streaming Media. Briefly, VVC is “codec next” from the perspective of MPEG (see image above) that’s due out in mid-to-late 2020. The Streaming Media article identifies the new “tools” in the codec, early performance results, and what we know about licensing. It’s way too early for most…
DetailsMy article, The State of CMAF: The Holy Grail or Just Another Format?, just published on the Streaming Media website. Here’s the enticing intro: The holy grail of streaming is a single set of files that you can safely deliver to all target endpoints. The most likely candidate to help achieve this is the Common…
DetailsThe Voronoi omnidirectional video metrics have the best correlation between test scores and subjective ratings than all measured 2D and 3D metrics according to its inventors. It’s an open-source metric you can download and learn to use below. I’ll be discussing the Voronoi metric in my upcoming talk on 2D and 3D video quality metrics…
DetailsOne of the gaps in my online course on Video Quality Metrics and my upcoming course on metrics at Streaming Media West was the ability to compute VMAF using FFmpeg on Wind. I know it’s been possible for quite a while now but since I’m not a coder I can’t compile the version of FFmpeg…
DetailsFFMPEG is a free command-line utility that serves as the engine for most of the largest cloud encoding farms in the world, public and private. But it also performs many simple and essential tasks that crop up in a studio or encoding facility, particularly if you do performance or benchmark testing. In this article, I’ll…
DetailsAt its most basic level, streaming media is the delivery of audio and video files from a server to a client over the internet or a cellular data network. The first streaming audio was delivered in 1995, while the first streaming video followed two years later; you can read more about the early history of…
DetailsWe’ve been following the story of DASH royalties since MPEG LA first announced the pool back in 2015. Recently, the pool stopped offering licenses, which seemed to cease any assertions of royalties. But as I just wrote about in Streaming Media magazine, one of the pool members, Helios Streaming along with Ideahub, sued Showtime, Vudu,…
DetailsI’m pulling together some materials for my pre-conference session at Streaming Media West (November 18-20 in Los Angeles) entitled Objective Quality Metrics 2D & 3D: What They Are, How To Compute Them, & How To Use Them. One lesson talks about “tuning” when encoding files to be measured with metrics like PSNR, VMAF, and SSIM.…
DetailsSo, the object of the exercise is a single FFmpeg script that encodes your files and creates the necessary master and media playlists. I took an initial stab here, but wound up with a script, “as ugly as someone else’s baby, particularly the need to duplicate the input file four times for the four streams.”…
DetailsI’m pulling together some materials for my pre-conference session at Streaming Media West (November 18-20 in Los Angeles) entitled Introduction to ABR Production and Delivery. One lesson shows the technology ecosystem needed to implement OTT streaming and identifies key vendors for each function. I figured I’d throw these slides out there to get comments on…
