Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

SVT-AV1 HDR Encoding (libsvtav1 with ffmpeg)
How about use the parameter "HighDynamicRangeInput" with command line "--enable-hdr 1"? It's from the official page: https://github.com/AOMediaCodec/SVT-AV1/blob/master/Docs/Parameters.md
I used the settings from the official page: https://github.com/AOMediaCodec/SVT-AV1/blob/master/Docs/svt-av1_encoder_user_guide.md

AV1 Video Codec
I think a more relevant front page link/summary would be that the open-source AV-1 codec has reached the v1.0.0 milestone (18 days ago).
You can see nVidia's hardware support here: https://developer.nvidia.com/video-encode-and-decode-gpu-sup...
The take-away is that nVidia only has hardware support for AV1 on the RTX 3000 Ampere series cards.
Intel supported AV-1 decoding in its Xe-LP GPUs in 2020.
Intel also reached v1.0.0 of its open-source codec 2 weeks age, here: https://github.com/AOMediaCodec/SVT-AV1
I am not aware of any other CPU or GPU that has an AV-1 codec built in.
- Seems like the SVT-AV1 documentation issue #1753 about missing presets explanation is fixed now. And it seems like the preset 0, 1 and 2 are the same thing. Plus tons of other useful encoding guidelines (like how to tune for animation etc.).

Ask HN: How can I learn about video encoding, h.264, ffmpeg, etc.
A good high-level breakdown of H.264: https://sidbala.com/h-264-is-magic/
