जब किसी फ़ाइल में अधिक ऑडियो ट्रैक होते हैं, तो VLC उनके नाम - या शीर्षक दिखा सकता है, मुझे ऑडियो> ऑडियो ट्रैक के तहत मेनू के बारे में निश्चित नहीं है।
जब मैं फ़ाइल को फिर से बताता हूं
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
नाम खो जाते हैं और केवल सामान्य "ट्रैक 1" और "ट्रैक 2" दिखाई देते हैं। मैं इसे कैसे रखूँ? या मैं एक कस्टम नाम कैसे सेट करूं।
कमांड का आउटपुट इस प्रकार है:
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

क्या आपने किसी और तरह का देखा है? उदाहरण के लिए "सराउंड ट्रैक"? या आप भाषा के विकल्प की बात कर रहे हैं?

हाँ, एक "चारों ओर" है और दूसरा "R128 स्टीरियो" है
