Answer 1

Se você tiver sorte, seu dispositivo de captura será reconhecido assim que você conectá-lo e estará pronto para uso. Se você fizer ls /dev/video* , deverá ver o dispositivo. Assumindo que é o único plugado, será / dev / video ou / dev / video0.

Se você não vir o dispositivo, talvez seja necessário procurar o driver apropriado. Este post sugere que é realmente um Geniaech EZ Grabber que foi renomeado, e usa o driver do uvcvideo.

Para testar o dispositivo, você pode usar o mplayer: mplayer /dev/video deve fazer isso.

Eu gosto do VLC para a maioria das coisas, e ele pode fazer streaming de vídeo a partir de um dispositivo de captura. Você pode instalar o VLC a partir do Synaptic. O VLC é muito fácil de usar, mas esta entrada do VLC Documentation Wiki deve ajudar você a começar.
