MakeMKV (libmmbd) for VLC, HandBrake and Kodi - Windows 32/64 bit - bluray playback
No longer useful
In MakeMKV, in "View", "Preferences" and Integration you can enable builtin system dll integration.
If apps are not listed, just enable System32 (and SysWOW64 for 32bit app on 64bit system) it work.

VP9 Encode Guide (ffmpeg, libvpx-vp9, vpxenc)
WIP
VP9 encode is very very slow ?
Yes and no. Unlike x265 use all core to speed up encode time, the low threaded libvpx-vp9 use for me 4 core of my Ryzen 3900X. Encode 4 video in the same time -> x4 "boost".
Force dynamic bitrate with b:v 0
Set quality level with -crf <quality level> is a integer (0 to 63)
libvpx use -deadline and ffmpeg -quality need to be set to good.
SVT-AV1 is the fastest multithreaded AV1 encoder
You can download up to date BtbN ffmpeg build with latest STV-AV1 code.
Aom-av1 is the official av1 decoder/encoder but it's the slowest and lacks of a real massive multithreading.
Rav1e is a xiph encoder project. It's also very slow but you can use multithreading with tiles.
Dav1d is a veryfast AV1 VLC decoder project.
Svt-av1 is an heavy multithreading intel decoder and encoder. It produce good quality but bigger file size.
It can produce 8 and 10 bit video with CRF (default), CQP, VBR and CBR (test).
Two pass are also available with standalone SvtAv1EncApp but not in ffmpeg.
