New issue by BlitDev on void-packages repository

https://github.com/void-linux/void-packages/issues/46823

Description:
Hi, I tried to use rav1e in ffmpeg, but it said "Unknown encoder 'librav1e'". Also there is no librav1e in ffmpeg encoders list (-encoders).

```ffmpeg -encoders | rg av1``` output:
```
V..... libaom-av1           libaom AV1 (codec av1)
V..... libsvtav1            SVT-AV1(Scalable Video Technology for AV1) encoder (codec av1)
```
