Tôi đã thiết lập Logitech c920. Với sự giúp đỡ từ một người dùng AskUbfox có kinh nghiệm, tôi đã cài đặt GUVCview, bảng điều khiển linux Video4 và trình kiểm tra tiện ích QT V4L2 tại đây. Tôi có thể thay đổi từ webcam tích hợp của Toshiba sang webcam ngoài bằng GUVCview.
Tuy nhiên, khi tôi bắt đầu một videochat trên Google Hangouts, nó sẽ tự động chọn máy ảnh máy tính xách tay tích hợp của tôi làm mặc định. Tôi muốn thay đổi cài đặt mặc định của mình để luôn sử dụng máy ảnh bên ngoài, nhưng tôi không thể tìm thấy tùy chọn này ở đâu. Tôi đang chạy Windows 7 và Ubuntu 12.04 LTS trên Toshiba Satellite L755
bộ nhớ: 3,8 Gib
bộ xử lý: CPU Intel® Core ™ i5-2410M @ 2.30GHz × 4
đồ họa: Intel® Sandybridge Mobile
Hệ điều hành 64 bit
đĩa: 40,2 GB
EDIT: Tôi đã thử Gstreamer-properties
trong thiết bị đầu cuối và thay đổi đầu vào mặc định trong video thành cam ngoài Logitech. Vẫn không có may mắn. Khi tôi "kiểm tra", tôi không nhận được hình ảnh nào và vẫn nhận được máy tính xách tay khi tôi mở GUVC.
EDIT thứ 2: Sau khi cài đặt Bộ chọn đa phương tiện trong thiết bị đầu cuối, tôi vẫn không thể tìm thấy nó trong Dash. Đây là phần đọc sau khi chạy lệnh:

Nếu tôi chạy Gstreamer-properties
trong thiết bị đầu cuối, tôi nhận được bộ chọn đa phương tiện. Tôi thay đổi đầu vào mặc định thành bên ngoài, đèn xanh lam trên cam bên ngoài sáng lên (khi tôi nhấn "kiểm tra"), nhưng không có hình ảnh. Đây là một ảnh chụp màn hình của các thiết lập
EDIT thứ 3: Sau khi chạy nó với quyền root, sudo gstreamer-properties
tôi đã thay đổi đầu vào mặc định thành webcam HD (cùng cài đặt với ảnh chụp màn hình trước đó) và vẫn còn khi tôi mở GUVC, nó sẽ mở dưới dạng camera của máy tính xách tay. Đây là những gì đã đọc sau khi chạy SUDO

Khi tôi cố gắng đóng Terminal, nó cho biết quá trình vẫn đang được sử dụng.
EDIT 4TH, ngày hôm sau:
Tôi theo liên kết dưới đây để Dumindu

và chạy nó qua thiết bị đầu cuối. Sau vài phút, kịch bản đã được thực hiện và tôi không nhận thấy bất kỳ lỗi hoặc lỗi nào (tôi sẽ đặt bản sao bên dưới). Tuy nhiên, khi tôi chạy, sudo gstreamer-properties
tôi nhận được thông báo "Bỏ qua plugin không có sẵn" như trên ^. Đầu vào mặc định trên bộ chọn hệ thống Đa phương tiện được đặt thành c920 HD cam, nhưng tôi vừa mở GUVC và nó mở camera máy tính xách tay. Đây là phần đọc sau sudo apt get install
