For all talk about the new AV1 codec or HEVC in HLS, the simplest and fastest way to save bandwidth costs and improve your viewer’s QoE is to deploy video optimization or per-title encoding. I explore why in a column now up on StreamingMedia.com. You can implement a simple form of per-title encoding with FFmpeg…
At NAB 2018 I gave a talk on applying quality metrics to 2D and VR video, and the video has just become available. So here’s the session description, and the video and a link to the handout is below. Choosing the number of streams in an adaptive group and configuring them is usually a subjective,…
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…
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…
Another of my sessions at Streaming Media. Here’s the description, download PDF below. T203. HOW-TO: Comparing Per-Title Encoding Options Wednesday, May 9: 1:45 p.m. – 2:45 p.m. Per-title encoding techniques customize the encoding ladder to match the encoding complexity of the source, saving bandwidth on easy-to compress videos and ensuring the quality of more complex…
One of my three sessions at Streaming Media East. Here’s the description; link to handout below. Note: one issue that came up during the discussion was the ability for systems to handle multiple language and captions. After the presentation, I heard from a representative from Go Easy Live who stated, “As additional informational, I confirm…
My first presentation at Streaming Media East. A complete lesson-based rewrite from previous workshops. Here’s the description, the download link is below. As video resolutions increase and target playback platforms multiply, video producers must leave their H.264/HLS/HDS comfort zone and expand into HEVC, VP9, and MPEG-DASH. This workshop is divided into multiple segments by target…
I know time is short, but I’ve gotten in touch with most vendors that offer this feature and am posting this (and using social media) so the word is out. Anyone who wants to participate, there’s still time. Here’s the description of the session: T203. HOW-TO: Comparing Per-Title Encoding Options Wednesday, May 9: 1:45 p.m.…
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…
From a Streaming Media perspective, NAB 2018 was all about the launch of the AV1 codec from the Alliance for Open Media. While at the show, I spoke with many different people from many different companies about the launch, and about other codec-related announcements at the show. You can read all about that in my…
