Mam skonfigurowanego Logitech c920. Z pomocą doświadczonego użytkownika AskUbuntu zainstalowałem tutaj GUVCview, panel sterowania Video4 linux i tester narzędzi QT V4L2. Jestem w stanie przejść z wbudowanej kamery internetowej Toshiba na zewnętrzną kamerę internetową za pomocą GUVCview.
Kiedy jednak uruchamiam wideochat w Google Hangouts, automatycznie wybiera on mój wbudowany aparat do laptopa jako domyślny. Chciałbym zmienić moje ustawienia domyślne, aby zawsze używać kamery zewnętrznej, ale nie mogę znaleźć, gdzie jest ta opcja. Używam Windows 7 i Ubuntu 12.04 LTS na Toshiba Satellite L755
pamięć: 3,8 Gib
procesor: procesor Intel® Core ™ i5-2410M @ 2,30 GHz × 4
grafika: Intel® Sandybridge Mobile
System operacyjny 64-bitowy
dysk: 40,2 GB
EDYCJA: Próbowałem Gstreamer-properties
w terminalu i zmieniłem domyślne wejście pod wideo na zewnętrzną kamerę Logitech. Wciąż nie ma szczęścia. Kiedy „testuję”, nie widzę obrazu, a po otwarciu GUVC wciąż mam kamerę do laptopa.
2. EDYCJA: Po zainstalowaniu selektora multimediów w terminalu nadal nie byłem w stanie go znaleźć w Dash. Oto odczyt po uruchomieniu polecenia:

Jeśli uruchomię Gstreamer-properties
terminal, dostaję selektor multimediów. Zmieniam domyślne wejście na zewnętrzne, niebieskie światło na zewnętrznej kamerze świeci (po naciśnięciu „test”), ale nie ma obrazu. Oto zrzut ekranu ustawień
3. EDYCJA: Po uruchomieniu go jako root przy sudo gstreamer-properties
zmianie domyślnego wejścia na kamerę internetową HD (takie same ustawienia jak na poprzednim zrzucie ekranu) i po otwarciu GUVC otwiera się jako kamera laptopa. Oto, co odczyt był po uruchomieniu SUDO

4. EDYCJA, następnego dnia:
Podążyłem za linkiem poniżej do Dumindu

i poprowadziłem to przez terminal. Po kilku minutach skrypt został ukończony i nie zauważyłem żadnych awarii ani błędów (poniżej zamieszczę kopię). Jednak kiedy uruchomiłem sudo gstreamer-properties
, otrzymałem takie same komunikaty „Pomijanie niedostępnej wtyczki” jak powyżej ^. Domyślne wejście w selektorze systemów multimedialnych jest ustawione na kamerę HD C920, ale właśnie otworzyłem GUVC i otwiera kamerę laptopa. Oto odczyt po sudo apt get install

Najpierw musisz zainstalować aplikację Multimedia Systems Selector
Następnie otwórz go, aw jego

sekcji możesz zmienić domyślną kamerę internetową.** Tę aplikację można otworzyć za pomocą terminalu, uruchamiając:

Ten rodzaj padł martwy w wodzie. Nie wiem czy powinienem opublikować kolejny wątek czy co. Po prostu próbuję ustawić moją zewnętrzną kamerę internetową jako domyślną kamerę internetową. Mam zainstalowany Gstreamer (na zdjęciu) Mam zainstalowany selektor systemów multimedialnych. Mam domyślne ustawienia w selektorze systemów multimedialnych do ustawienia w kamerze internetowej c920, a jednak po otwarciu czatu wideo lub GUVC otwiera się kamera laptopa. Mam w tym trochę pomocy i przeszedłem. Ale nadal nie mogę sprawić, żeby zadziałało. Czy ktoś ma jakieś pomysły, czy powinienem publikować gdzie indziej? Dzięki

Myślę, że mam rozwiązanie. Nie wiem, czy możesz sprawić, by własny aparat laptopa znów działał, ale przynajmniej mogłem zrobić domyślnie USB.
Zrobiłem tak:
sudo rm /dev/video0
Po tym nie mogłem w ogóle uruchomić Camorama Webcam Viewer.
sudo chmod -R 777 /dev
To daje ci możliwość zmiany nazw plików
mv /dev/video1 /dev/video0
Spowoduje to zmianę nazwy kamery USB na dev0
Potem mogłem automatycznie zobaczyć moją kamerę USB, kiedy otworzyłem Camorama Webcam Viewer. Mam nadzieję, że to pomoże.
