Hello, Motitz

 See the output of the command:

 root at darkstar:~# ffmpeg -codecs | grep libvpx
ffmpeg version 3.2.4 Copyright (c) 2000-2017 the FFmpeg developers
  built with gcc 5.5.0 (GCC)

libvpx )
 DEV.L. vp9                  Google VP9 (decoders: vp9 libvpx-vp9 )
(encoders: libvpx-vp9 )

 However, when trying to record on the simplescreenrecorder the error
appears:

[VideoEncoder::PrepareStream] Usando formato de pixel yuv420.
[libvpx @ 0x129dd00] v1.5.0
[libvpx @ 0x129dd00] Failed to initialize encoder: ABI version mismatch
[BaseEncoder::Init] Erro: Não foi possível abrir o o codec!
[PageRecord::StartOutput] Erro: Ocorreu um erro durante a inicialização.

Thanks
