Ronald Bultje

Founder, Two Orioles


Ronald was born in Groningen, in the north of the Netherlands. He got his college degree at the University of Utrecht and then a PhD in developmental neuroscience at Cornell University in New York. After that, he worked in Google's video algorithms team and was part of the team that designed and released VP9. He also gave the Google I/O talk in 2013 when VP9 was originally introduced to the world. After leaving Google, Ronald founded Two Orioles, where he and his team do research and development of video coding algorithms, decoders and encoders. In his free time, he's also an enthusiastic FFmpeg contributor. Ronald has been married for 10 years, has 2 kids and lives in New York City.

Conference Talk

High-performance AV1 coding with dav1d and Eve

In this talk, we will discuss dav1d and Eve. dav1d is Videolan's opensource AV1 decoder, and Two Orioles is one of the principal contributors to this project. We will discuss performance characteristics, such as CPU usage, memory usage and multi-threading scalability, compared to libaom and commonly-used decoders for other popular video codecs. After that, we will discuss Eve, Two Orioles' commercial video encoder. Eve targets the high-end VoD market. We will discuss Eve in terms of its performance characteristics, such as quality-per-bit, CPU usage, multi-threading scalability, visual quality, and use that to compare it to several publicly available and opensource encoders for popular video codecs. As we will demonstrate, although the Alliance for Open Media has shown considerable gains with AV1 compared to previous-generation video codecs, Two Orioles has been able to go well beyond the bounds of the reference software with the dav1d decoder and Eve encoder, setting a new standard in fast and high-quality AV1.
