আমি যখন FFmpeg এবং x264 কোডেক ব্যবহার করে একটি এক্সআর অনুক্রমটিকে কুইকটাইম এমওভি ফাইলে রূপান্তর করি, তখন এটি ভিডিওটি কোড করে - তবে কুইকটাইম প্লেয়ার এবং উইন্ডোজ মিডিয়া প্লেয়ারে এটি কেবল কালো!
তবে আমি যখন ভিএলসি দিয়ে এটি খুলি তখন আমি চিত্রটি দেখতে পারি এবং এটি দেখতে ভালই লাগে। আমি যখন EXR এর পরিবর্তে JPG সিকোয়েন্স সহ একই জিনিসটি চেষ্টা করি তখন এটি পুরোপুরি কার্যকর হয়! কারও কি ধারণা থাকতে পারে যে তা কী হতে পারে?
আমার FFmpeg কোডটি এখানে:
ffmpeg -y -i C:/seq_v001.%04d.exr -c:v libx264 -preset slow -crf 17 C:/out.mov
