আমার লগিটেক সি 920 সেট আপ আছে। অভিজ্ঞ এসকিউবুন্টু ব্যবহারকারীর সহায়তায় আমি এখানে জিইউভিউভিউ, ভিডিও 4 লিনাক্স নিয়ন্ত্রণ প্যানেল এবং কিউটি ভি 4 এল 2 ইউটিলিটি পরীক্ষক ইনস্টল করেছি। আমি আমার তোশিবার তৈরি ওয়েবক্যাম থেকে জিইউভিউ ভিউ ব্যবহার করে আমার বাহ্যিক ওয়েবক্যামে পরিবর্তন করতে সক্ষম।
তবে, আমি যখন গুগল হ্যাঙ্গআউটে একটি ভিডিওচ্যাট শুরু করি, এটি স্বয়ংক্রিয়ভাবে আমার বিল্ট ইন ল্যাপটপ ক্যামেরাটি ডিফল্ট হিসাবে নির্বাচন করে। আমি সর্বদা বাহ্যিক ক্যামেরা ব্যবহার করতে আমার ডিফল্ট সেটিংস পরিবর্তন করতে চাই তবে এই বিকল্পটি কোথায় তা আমি খুঁজে পাচ্ছি না। আমি তোশিবা স্যাটেলাইট L755 এ উইন্ডোজ 7 এবং উবুন্টু 12.04 এলটিএস চালাচ্ছি

সম্পাদনা: আমি Gstreamer-propertiesটার্মিনালে চেষ্টা করেছি এবং ভিডিওর অধীনে ডিফল্ট ইনপুটটি লজিটেক বহিরাগত ক্যামে পরিবর্তন করেছি। এখনও ভাগ্য নেই। আমি যখন "পরীক্ষা" করি তখন আমি কোনও ছবি পাই না এবং আমি জিইউভিসি খুললে ল্যাপটপ ক্যাম পাই।
২ য় সম্পাদনা: টার্মিনালে একাধিক মিডিয়া নির্বাচক ইনস্টল করার পরেও আমি ড্যাশটিতে এটি খুঁজে পাচ্ছিলাম না। কমান্ড চালানোর পরে রিডআউটটি এখানে:

আমি Gstreamer-propertiesযদি টার্মিনালে চালাই তবে আমি মাল্টিমিডিয়া নির্বাচক পাই। আমি বাহ্যিকতে ডিফল্ট ইনপুট পরিবর্তন করি, বহিরাগত ক্যাম লাইটগুলিতে নীল আলো (যখন আমি "পরীক্ষা" টিপবো) তবে কোনও চিত্র নেই। সেটিংগুলির একটি স্ক্রিনশট এখানে

আমি ডুমিন্ডুর নীচের লিঙ্কটি অনুসরণ করেছি
