I’ve been asked for an update on the Sisvel AV1/VP9 pool situation; here’s what we know. Before beginning, as I wrote about here, I am working as a consultant with Sisvel during the launch. To recap, Sisvel announced their pool late March: Before signing on as a consultant, I wrote two articles for Streaming Media…
Embedded below is a free lesson from my course, Produce Videos with FFmpeg: The Beginner’s Course (http://bit.ly/learn_ffmpeg). The previous lesson in the course describes when you can use the -s command to set resolution; this lesson details your options when you can’t. This typically occurs when the display aspect ratio of your output is different from…
I’m launching a new course entitled Encoding and Packaging for Multiple Screen Delivery. It’s an advanced course detailing how to create and configure encoding ladders using objective quality metrics like VMAF, packaging for DASH/HLS (both static and dynamic), CMAF, per-title encoding, and more. The course is designed for professionals who need to get up to…
In this video, I interviewed Sisvel CEO Mattia Fogliacco about the new VP9 and AV1 patent pools. Our discussion covered: Background on Sisvel Due diligence performed before Sisvel formulated the pool to confirm the validity of their patents Details about the royalty structure and what’s covered by the license (and what’s not covered) The image…
Luxembourg-based Sisvel International SA announced patent pools for VP9 and AV1 yesterday targeted at consumer display devices (smartphones, TVs, etc) and consumer non-display devices (set-top boxes and OTT devices). Here’s what we know from this article on Streaming Media) and this Q&A. The standard rate for VP9 is € 0.24 for display devices and €…
Just a quick note to let you know that I’m launching a video course entitled, Produce Videos with FFmpeg: The Beginner’s Course. The course costs $29.95 and includes 32 video lessons totaling about 3 hours of video with downloadable PDFs of the content covered. Students will learn basics like how to configure video resolution and…
Sorry for the visual but couldn’t resist. Just got the following email from Unified Patents. All the normal caveats apply; I haven’t reviewed the filings (and won’t) and Unified may not succeed though they’ve had some recent successes. Why the hate on Velos? In contrast to the transparency with which MPEG LA and HEVC Advanced…
I frequently use the VMAF quality metric to analyze encoding parameters and compare codecs. In my experience, VMAF scores tend to match my own subjective quality observations and the fact that Netflix uses it gives the metric great credibility. Originally, there was only one VMAF version, but Netflix has added both a 4K model and…
According to the last published statistics, in June 2017, Whatsapp users sent over 1 billion video messages a day. This obviously represents only a fraction of the market and daily traffic has certainly has grown since then. At the same time, 4K cameras have become standard and mobile screen resolutions have increased in size and…
I just finished a project that involved encoding lots of downloaded YUV test files, which is something I never tried before. The problem is that there’s no resolution or frame rate information in the file header, so you have to detail all this in the command string. My first crack at the problem evolved into this…
