Monthly Video Meetup

If you haven't been to the Demuxed website recently, you should go check it out! We'll start making public announcements next week, but there's a slew of speakers that may have made their way onto the website already. Spoiler alert: there's a ton of really great content.

This month is in the more-than-capable hands of the venerable Nick Chadwick, so if you have any questions ahead of the event, ping him on Twitter (@chadnickbok) or message here on Meetup.

Without further ado, our 2 top notch speakers/talks this month!

Yueshi Shen (Twitch) - VP9 Transcoding for Live eSports Broadcast

To reduce the operational cost, Twitch is building a VP9 live-encoding solution that can deliver broadcast-level video quality with 25+% bitrate savings. Based on our feasibility study, FPGA is the only available solution in the market right now. On the other hand, future high-density solutions can be based on ASIC if there emerge more cost effective encoder SoC products.

Yueshi will explain the thought process of selecting VP9 as Twitch's next-gen video codec format, particularly will elaborate 1) legal risk, 2) decoder support, 3) compression gain.

Zhi Li (Netflix) - VMAF: the Journey Continues

VMAF started as a research project to address the need to automate quality assessment of Netflix's vast video catalog. In June 2016, we open sourced VMAF on Github, and since then it has gone through some substantial updates. In this talk, I will focus on its latest improvements and enrichment, including speed optimization, more accurate models to predict mobile and 4KTV viewing conditions, and adding a confidence interval to quantify the level of confidence in the prediction. Lastly, I will give a sneak peek on what is coming up next in VMAF.
