Two Orioles


Big Apple Video Conference 2019 — High-performance AV1 coding with Eve and dav1d

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.
