Hi Cosmin,
This happened many years ago. See the discussion here:
https://patchwork.ffmpeg.org/project/ffmpeg/patch/20201221060710.12230-6-nuomi2021@gmail.com/#60589
Now that we have an internal vvc decoder, we can focus on improving it.
As for the encoder, it is far more complex than the decoder. Reasonable to
wrapper other libraries just like libx264 and libx265...
