Here’s the description; download handout below. T101. HOW-TO: Fine-Tuning Your Adaptive Encoding Groups With Objective Quality Metrics Tuesday, November 13: 10:30 a.m. – 11:15 a.m. Choosing the number of streams in an adaptive group and configuring them is usually a subjective, touchy-feely exercise, with no way to really gauge the effectiveness and efficiency of the…
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…
W4. Encoding Live & VOD For HEVC/HLS Monday, November 12: 1:30 p.m. – 4:30 p.m. Apple’s support for HEVC in HLS is a groundbreaking event that opens up hundreds of millions of HEVC capable players. If supporting this spec is on your short-term development schedule, check out this workshop. The workshop starts by reviewing the…
I have a confession to make. Though I’ve attended dozens of Streaming Media conferences, I’ve never attended a kickoff session. Not, of course, because the content wasn’t information and insightful, but because I’m always scurrying about trying to finish my own presentations. This dubious accomplishment ends at Streaming Media West next month, when Roger Pantos,…
I’ve been pondering what drives codec adoption since I joined compression company Iterated Systems back in 1993. Tonight, I have the opportunity to explore the subject in detail at a meetup sponsored by Bitmovin as an adjunct to the Demuxed conference here in San Francisco. Entitled The Battle of the Codecs: AV1 vs VVC, the…
I recently wrote an article for Streaming Media where I tested AV1 playback from YouTube in Chrome. I mentioned that I couldn’t make Firefox Nightly work, though it also should play the YouTube content. Some folks from Mozilla got in touch and detailed the steps to make it work. 1. Download Firefox Nightly here. 2. Go to…
A recent consulting project involved computing the VMAF, SSIM, and PSNR scores of 30 fps 480p video encoded from a 60 fps 1080p source file. I’ve not performed measurements like this in the past and assumed that simply converting the 60 fps sources file to 30 fps via the “-r” option would convert from 60…
I’m not going to IBC, but if you are, please check out AV1 hardware encoding acceleration from Socionext. Here’s the blurb from the press release. There will be a demonstration of the world’s first hardware-based implementation of an AV1 encoding system. AV1 is a new, advanced video data compression standard established by theAlliance for Open Media,…
My first look of the AV1 codec is up on Streaming Media Magazine. Here’s the pithy summary. “These tests revealed glimpses of very alluring quality as compared to existing codecs, but at a current encoding cost that’s far beyond what the vast majority of video publishers can afford to pay. How many devices will play…
Number of hours of streaming required to recoup 60-minute encoding cost. Author’s note: The author would like to acknowledge the shocking fact that he is not perfect and that this lack of perfection often reveals itself, quite embarrassingly, in spreadsheet-intensive articles. I did the best I could and checked every number and assumption multiple times, but…
