আমি একটি এভিআই ফাইলকে এমপি 4 ফাইলে রূপান্তর করার চেষ্টা করছি। ভিডিও স্ট্রিমটি একটি এক্সভিআইডি যেখানে অডিও স্ট্রিমটি এমপি 3।
সমস্যাটি হ'ল ফলস্বরূপ এমপি 4 ফাইলটি ম্যাকের কুইকটাইম প্লেয়ারে খেলতে পারা যায় না। এটি ভিএলসিতে খেলে। যদিও এটি কোনও চুক্তিভঙ্গকারী নয়, আমি জানতে চাই যে এই জাতীয় সমস্যাগুলির ফলাফল কীভাবে করা যায়।
কমান্ড এবং এর আউটপুট নিম্নরূপ:

[mpeg4 @ 0x7fcddb018000] Video uses a non-standard and wasteful way to store B-frames ('packed B-frames'). Consider using a tool like VirtualDub or avidemux to fix it.
