I was paranoid that this would only be the case for AVX-enabled CPUs, but even on my AVX-less Haswell Pentium G3258 I was seeing ~50% faster performance than what I would get via MPC-HC v1.8.4 with its built-in LAVfilters.

I also just tried a very recent nightly build of LAVfilters as well (0.73.1-30 built on 2019-03-08), and unfortunately the resulting performance indicates that it's likely still using the AOM decoder.
Reminder that even the newest Pentiums lack AVX. Heck in terms of actual IPC and performance-per-clock, my own Pentium is only two generations old, and one of those generations were practically skipped-over for the desktop.

LAV will be switching to dav1d 0.2.1 soon, which was released only minutes ago. I wanted to use 0.2.0 already but knowing that a small improvement was coming up shortly, it made sense to wait.

The VLC Dev and 3.0 branches now use dav1d 0.2.1.
Here are new Nightly builds for:Chimera (8-bit 1080p) now plays most scenes fluently on my Galaxy S7 (Exynos 8890 with 4x Mongoose 1, 4x Cortex-A53 and 4GB LPDDR4). Summer in Tomsk 1080p (from Elecard) plays fluently, while Summer Nature 1080p still has a stutter here and there (bitrate is a lot higher). 720p videos are now decoded without a hitch. |

Android Q introduces support for the open source video codec AV1. This allows media providers to stream high quality video content to Android devices using less bandwidth. In addition, Android Q supports audio encoding using Opus - a codec optimized for speech and music streaming, and HDR10+ for high dynamic range video on devices that support it.
The MediaCodecInfo API introduces an easier way to determine the video rendering capabilities of an Android device. For any given codec, you can obtain a list of supported sizes and frame rates using VideoCodecCapabilities.getSupportedPerformancePoints(). This allows you to pick the best quality video content to render on any given device. |

And Google REALLY likes objective metrics. They trust a number from a computer more than their own eyes. It's one of those "looking where the light is" kinds of problems. |

Geez, no wonder people like Elon Musk are so concerned about certain tech companies going all-in on deep A.I.

It would seems that LAVFilters v0.74.1 and therefore also MPC-HC v1.8.6 are now using dav1d, resulting in similar performance gains that were seen in MPC-BE beta builds (which I previously measured as being ~50% faster than MPC-HC v1.8.4 and its included LAVFilters v0.73).
