যখন কোনও ফাইলে আরও অডিও ট্র্যাক থাকে, তখন ভিএলসি তাদের নাম - বা শিরোনাম প্রদর্শন করতে পারে, আমি অডিও> অডিও ট্র্যাকের অধীনে মেনুতে পরিভাষা সম্পর্কে নিশ্চিত নই।
আমি যখন ফাইলটি পুনরায় পুনর্নির্মাণ করি
ffmpeg -i input.mp4 -map 0:0 -map 0:1 -map 0:2 -c:v libx264 -preset slow -profile:v high -crf 17 -c:a copy output.mp4
নামগুলি হারিয়ে যায় এবং কেবল জেনেরিক "ট্র্যাক 1" এবং "ট্র্যাক 2" উপস্থিত হয়। আমি কীভাবে এটি রাখব? বা আমি কীভাবে একটি কাস্টম নাম সেট করব।
কমান্ডের আউটপুট এরকম:
ffmpeg -ss 0 -i Shades_of_winter_24FPS_x264_5.1_AC3+R128.mp4 -map 0:0 -map 0:1 -map 0:2 -vf "ass=p.ass" -c:v libx264 -preset slow -profile:v high -crf 17 -c:a copy -metadata:s:a:0:0 -language="ble" -metadata:s:a:1 language="bli" -metadata:s:a:0:2 title="bla" -t 6 a.mp4

আপনি অন্য কোন ধরণের দেখেছেন? যেমন "আশপাশের ট্র্যাক"? অথবা আপনি ভাষা বিকল্পটি উল্লেখ করছেন?

হ্যাঁ, একটি হ'ল "চারপাশে" এবং অন্যটি "আর 128 স্টেরিও"
