Boa tarde,,, Eu usava o Antergos mas, como descontinuaram o projeto acabei migrando de vez para o Arch.
Tudo estava funcionando perfeitamente até que minha filha precisou usar a Webcam integrada ao meu Laptop ASUS A53S. Foi nesse momento que percebi que ela não estava funcionando mas, funcionava perfeitamente no Antergos e funciona no Windows 10.
Acontece o seguinte: se eu abro o v4l2 a luz da Webcam acende (fica verde) mas não aparece imagem. A mesma coisa acontece no hangouts com videoconferência.

usando o comando $dmesg | tail com v4l2 aberto tenho esse resultado:

$ dmesg | tail

Tentei seguir as instruções => https://wiki.archlinux.org/index.php/Webcam_setup
Resultados:
. a câmera não inicializa...
. xawtv não carrega...

Alguma ideia???

poderia ser falta de algum codec como o ffmpeg ou o gstreamer?

Bom dia, obrigado pela ajuda.
Então, chequei e eles estavam instalados mas mesmo assim rodei um pacman -S para reinstalá-los.
Mas, o problema ainda continua.

novo dmesg | tail sem abrir o v4l2:

Bom dia.
Se achar que vale, experimenta testar/instalar este aplicativo aqui e verifica o comportamento do vídeo da tua Webcam (OBS) https://www.archlinux.org/packages/community/x86_64/obs-studio/
