আমি 9 ক্যামেরা ব্যবহার করে একটি সঙ্গীত পারফরম্যান্স রেকর্ড করতে এবং প্রতিটি ক্যামেরা থেকে সংগীতের অংশটি সঠিকভাবে কাটাতে ফ্রেম ব্যবহার করি। যখন আমি ffmpeg এর সাথে 3x3 ফর্ম্যাটে তাদের খুঁজে বের করার চেষ্টা করি, তখন ভিডিওগুলির জন্য সময়টি একে অপরের থেকে এক সেকেন্ড পর্যন্ত বন্ধ হতে পারে। GUI বাণিজ্যিক পণ্য দিয়ে তাদের একত্রিত করা ঠিক আছে তবে আমি ffmpeg এর সাথে একটি কমান্ড লাইন পদ্ধতি ব্যবহার করতে চাই। আমি ব্যবহার করছি কমান্ড এখানে:

9 টি ভিডিওকে একে অপরের সাথে সিঙ্ক করার জন্য আমি কীভাবে ভিন্নভাবে কাজ করব? ধন্যবাদ।
আমি শুধু 9 অভিন্ন ভিডিও দিয়ে এটি করার চেষ্টা করেছি। উপরের বাম (প্রথম) ভিডিও বাকি সমস্ত সাথে সিঙ্ক আউট হয়। 2 throught 9 visually একে অপরের সাথে সিঙ্ক হয়। অডিও শুধুমাত্র প্রথম সঙ্গে সিঙ্ক হয়।
