Estou executando este comando:

ffmpeg -init_hw_device qsv=hw -filter_hw_device -f rawvideo -pix_fmt yuv420p -s:v 2560x1440 -i normal-desktop-use-1440p.mkv -c:v h264_qsv - b:v 5M output.mp4

Estou tendo o erro a seguir:

Eu esperava que o ffmpeg codificasse meu vídeo usando um codificador h264 acelerado por hw via Intel QuickSync.

Se eu fizer ffmpeg -encoders | grep qsvisso, recebo o seguinte:
