मैं ffmpeg और a का उपयोग करके एक वीडियो में एक उपशीर्षक जोड़ने की कोशिश कर रहा हूं .srt फ़ाइल।
कमांड का उपयोग करना:
ffmpeg -i videopath.mp4 -i subtitlefilepath.srt -c:v libx264 -preset ultrafast -ar 44100 -ac 2 -ab 128k -strict -2 videooutput.mp4
.srt फ़ाइल जैसा दिखता है
1
00:00:00,30-->00:00:05,30
Sample sub title for video
उसके बाद 30 क्या है duration?

मैं वीडियो पर कोई उपशीर्षक नहीं देख सकता। समस्या कहां है?
क्या आप अगली बार आउटपुट को ठीक से फ़ॉर्मेट करने का ध्यान रख सकते हैं एक पंक्ति में इसे पढ़ना मुश्किल है। धन्यवाद
