আমি কয়েক মিনিটের ছোট ক্লিপে 20 মিনিটের দীর্ঘ ভিডিও ভাগ করছি। কমান্ড মত
ffmpeg\\ffmpeg -i nx_1.avi -ss 399.37 -t 1 ka1_2.avi
Ffmpeg একটি subfolder হয়।
এটি আমার বেশিরভাগ ভিডিও ফাইলগুলির জন্য খুব ভাল কাজ করে। সমস্যাটি একটি ফাইল, যে ফাইলের জন্য, কিছু সেগমেন্টযুক্ত ক্লিপটিতে শুধুমাত্র অডিও থাকে, প্রাসঙ্গিক ভিডিও ক্লিপে স্পষ্টভাবে লেখা হয়নি। (নীচের লগ ফাইল সংযুক্ত।)। কিন্তু অন্য অংশে segmented ক্লিপ ভিডিও ভাল। অডিও এবং ভিডিও উভয় ঠিক আছে। আমি আসল ভিডিওটির সমস্যাযুক্ত অংশকে ঘিরে রাখার জন্য এবং এটি পুনরায় চালানোর জন্য একটি দীর্ঘ ক্লিপ ভাগ করার চেষ্টা করেছি। ক্লিপ সমস্যাযুক্ত অংশ পর্যন্ত জরিমানা নাটক, এটি সমস্যাযুক্ত অংশ শুরুতে froz।
আমি avi অনুসন্ধান করতে ffprobe ব্যবহার করি, এটি বলে যে ওডিএমএল সূচকটি অবৈধ। আমি অনুমান এই সমস্যা।
কিভাবে আমি এই সমস্যার সমাধান করতে পারে?

আমি নিজেকে দ্বারা কারণ খুঁজে পাওয়া যায় নি। ভিডিও 4 জি চেয়ে বড়। আমি 64bit FFmpeg ডাউনলোড। তারপর সবকিছু ঠিক আছে মনে হচ্ছে। ODML সূচী অবৈধ বার্তাটি বিভ্রান্তিকর।
