In the quest to deliver video at higher quality and lower latency, the streaming media industry is home to an ever-changing array of video formats, codecs, and delivery protocols. Look here for the latest news and trends in HEVC, AV1, VVC, CMAF, WebRTC, MPEG standards, royalties, just-in-time packaging, and more.

Practical Approaches to Sustainable Streaming

In this article I'll expand on prior sustainability approaches, detail reasons to consider additional areas of power-consumption optimisation, and invite diverse stakeholders across streaming workflows to engage with Streaming Media magazine, GoS, and like-minded stakeholders in a mid- to late-2023 initiative around the LESS Accord, with an overall goal of readers recommending measurable best practices for consideration by September 2023.

The State of Video Codecs 2023

Welcome to your codec update for 2023. I'm here to help you decide whether it's time to go all in on AV1, VVC, LCEVC, or EVC or whether it's better to stick with H.264, VP9, and HEVC. Along the way, I'll include 2022-2023 updates to identify significant changes that have occurred since last year.

How to Script for FFmpeg Using PowerShell and BASH

FFmpeg was designed as a cross-platform solution for video and audio recording, conversion, and streaming using simple static command lines. Using variables and "for loops" in a command string simplifies the reuse of existing scripts and helps automate their operation. While you can't use these scripts in the Windows Command window, you can use Microsoft PowerShell in Windows and Bash on Linux and the Mac. In this tutorial, you'll learn how to create and run such scripts with PowerShell and Bash.

Google Chrome Plays HEVC: What Does it Mean?

In late September, Google quietly let slip the news that it now offers playback support for HEVC in Chrome when it's already available in the underlying platform. This is bigger news than Google is letting on, but its immediate impact remains to be seen. We surveyed a number of experts and analysts to gauge its meaning for increased HEVC usage and more, and how it affects DRM and HDR.

In per-title encoding, an encoding service creates a unique encoding ladder for each video file. While available for live streaming, per-title encoding is most often utilized with video on demand.

The Algorithm Series: QUIC Ways to Stream

Will 2022 be the year UDP finally shows its streaming mettle? The Quick UDP Internet Connections (QUIC) protocol might make the difference. First, though, OTT platforms need to make technical decisions about HTTP/3 that could further fragment the market.

The Past, Present, and Future of Per-Title Encoding

Video encoding began as a one-dimensional data rate adjustment that reflected the simple reality that all videos encode differently is now a complex analysis that incorporates frame rate, resolution, color gamut, and dynamic ranges, as well as delivery network and device-related data, along with video quality metrics.

Buyers' Guide to VOD Encoders

What's the best solution for your video on-demand encoding needs? That depends, but this guide will help you figure out which questions to ask.

How Does VVC Measure Up Right Now?

VVC today can be both useful and usable; let's hope that VVC IP owners can formulate a royalty policy that delivers the same.
