hi
I have not tested this either but as I have no programming skills I cheat and use package binutils ...command strings
strings GoogleTalkPlugin | grep dev
gnu_dev_major
gnu_dev_minor

and video capture device index,

Inference.....pay attention to your video4linux setup
and pa_stream_get_device_index made me think that maybe pulseaudio is needed?
strings GoogleTalkPlugin | grep pulseaudio

good luck
