Codecs

MPEG is working on a new coding standard called Versatile Video Coding (VVC). A colleague recently sent me a presentation from Thierry Fautier, VP Video Strategy at Harmonic, which contained some preliminary encoding results to be formally presented at a paper given at IBC. The presentation was from a short talk Thierry gave at the Mile High Video 2018 conference. The presentation …

The launch of FFmpeg 4.0 gave many compressionists their first chance to test the new AV1 codec, which is included in experimental form. For the first time, you had a single encoder that could produce all relevant codecs: H.264 with the x264 codec, HEVC with the x265 codec, VP9 using the Google Libvpx-vp9 codec, and AV1 using the LibAOM codec. …

AV1 has been all consuming from a mindshare perspective for many streaming professionals, but the fact of the matter is that unless you’re distributing stream quantities on par with Netflix, YouTube, Amazon, and Hulu, AV1 won’t be relevant for at least two years, maybe longer. I discuss why in my Streaming Media article, Return of the Codec Wars: A New Hope—a …

A recent report published by Unisphere Research and Streaming Media magazine, and sponsored by Beamr, reveals some interesting data on HEVC adoption. Entitled Real-World HEVC Insights: Adoption, Implications, and Workflows, the report is available for free download on StreamingMedia.com (registration required) and is authored by my colleague Tim Siglin, a Streaming Media contributing editor and founding executive director of the …

A recent article in IPWatchdog analyzed HEVC-related patent ownership and found that “only one-third of relevant patents have been declared in patent pools.” So, even companies that license from all three pools are at substantial risk of challenges from other IP owners. With a new standard coming, MPEG needs to update its licensing policies, not its technology. The article was …

Much has been made about Google’s support for HEVC in Android, including I hate to say, by me. A recent look at the Android spec while preparing for a Streaming Media Workshop, however, seems to indicate that this support is practically irrelevant. Here’s why. If you click over to the Android Supported Media Formats page, you’ll see details regarding the supported codecs. …

This was a pre-conference workshop; here’s the description, download the handout below. Note that there are two sets of handouts, one from Jan, the other from RealEyes. W3. Encoding Live & VOD For HEVC/HLS Monday, May 7: 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. …

One of my sessions at Streaming Media East. Here’s the description; download the handout below. T102. HOW-TO: Comparing AV1, VP9, HEVC, & H.264 Tuesday, May 8: 11:45 a.m. – 12:30 p.m. Many content distributors and aggregators still use H.264 as their primary, if not exclusive, codec, but the bandwidth savings promised by newer, more powerful codecs are alluring. Those considering …

While at NAB, I produced a short video with Beamr CTO Dror Gil and Dirk Griffioen from Unified Streaming, which sells a variety of streaming-related software, including modules for ABR packaging. The primary topic was encoding and packaging with HEVC in HLS. Dror also gave a brief demo of Beamr’s new Transcoder product. During the talk, we covered sub-topics like the suggested encoding …

With streaming video data rates, less is always more, unless of course, lower data rates mean visible artifacts. I just finished a review of the ZPEG Engine for x264, which produced bitrate savings of 21% without blocks, banding, mosquitoes, or other problems that would be noticeable by typical viewers. This was an average saving; the data rate reduction in some …
