SME-2019 – FFmpeg Hardware VES101. Benchmarking FFmpeg’s Hardware Codecs Tuesday, May 7: 10:30 a.m. – 11:30 a.m. Hardware codecs in FFmpeg like those from Intel and NVIDIA deliver significant performance gains over x264/x265, but have a reputation for lower quality and use a completely different command set.

I was preparing for the codec discussion of my preconference sessions next week at Streaming Media East and visited www.caniuse.com to report codec availability. While I expected H.264 (96.96%) and VP9 (80.78%) to easily win, and they did, I was surprised to find AV1 availability at 32.46%, well ahead of HEVC at 16.71%. Digging into the numbers, I noticed that …

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 and produced one video interview …

Just a brief note to let you know that I’ve signed on as a consultant for Sisvel regarding their launch of the AV1 and VP9 patent pools. What?

A couple of additional data points on AV1 encoding as follow-ups to my Streaming Media article here. First, a colleague asked about 4K encoding times on Twitter. Second, a reader recommended using the row-mt switch for VP9. So, I encoded a ten-second 4K test file on the same single-CPU ZBook as the Streaming Media article. I used the same basic …

When I first tested AV1 encoding back in August 2018 encoding times were glacial and seriously detracted from the potential usability of the codec. Table 1 from that story tells the tale. Unless otherwise indicated, all encoding times are on my HP ZBook notebook powered by a single 2.8 GHz Intel Xeon E3-1505M v5 CPU. In addition, LibVPx is the …

In this January 2019 article in Streaming Media Magazine, I reported that two patent holders in the MPEG-LA patent portfolio group had sued Huawei and ZTE in Germany for patent infringement and had won.
