guvcview não funciona com a webcam logitech c270

Question

Eu comprei recentemente uma webcam c270 da logitech e funciona com queijo; no entanto, não funciona com o guvcview. Eu purgou completamente o queijo do computador. Então eu removi e reinstalei guvcview, mas ainda não está funcionando. Eu até tentei iniciar a partir da linha de comando. mas sem sorte. Qualquer ajuda apreciada. obrigado de qualquer maneira aqui estão os logs. para qualquer um corajoso o suficiente ... Eu acho que pode estar faltando driver e / ou codecs (vídeo)
