Finding the Equivalent x264 Commands for FFmpeg
Most of the x264 commands that I use in FFmeg are simple and well documented. Today, I had to duplicate a Handbrake preset that included some obscure x264-specific configuration options like the following: cabac=0:aq-mode=3:slices=24:direct=auto:subme=8:trellis=1:deblock=-2,-1:me=umh Cabac, I got, but most of the rest I use the default setting for the selected preset. Since Handbrake was displaying x264 commands which are different …

Figure 1. BD-rate savings from AV1 as published by Facebook. When Facebook compared the AV1 codec to VP9 and two flavors of H264, their researcher precisely stated, “In terms of PSNR, the average BD-rate savings of AV1 relative to x264 main, x264 high and libvpx-vp9 were 51.0%, 47.0% and 29.9%, respectively.” This means that AV1 delivered the same quality as …

As recently as June, HEVC seemed to have more momentum than the Golden State Warriors and New England Patriots combined, courtesy of Apple’s adding HEVC to HLS.

According to Moscow State University (MSU), AV1 is the highest quality codec available, besting both HEVC and VP9—when considering quality only, and not encoding speed,. More interesting is that in normal operating modes, VP9 produced higher quality than HEVC. These are just two of several compelling findings from the recently completed MSU 2017 Codec Comparison Report. As you’ll read below, …

For many, this announcement raised more questions than answers, which we hope to address in this article.

It’s easy to imagine the deployment of HEVC as a case study in business and technology schools about how not to launch a technology. Not only do you have a launch cycle that clearly limited adaption, you also have classic illustrations of two of the major problems related to standard-essential patents, patent holdup, and royalty stacking. Patent holdup refers to the practice …
