ffmpeg - merge mp3 and mp4 (duration difference)
8 décembre 2017, par dfionovI’m trying to merge mp4 and mp3 files with ffmpeg.
mp4 duration - 9.800 sec, mp3 - 58.540 sec. So i using -shortest key.
Code :ffmpeg -i video.mp4 -i audio.mp3 -c:v libx264 -c:a aac -strict experimental -shortest output.mp4After that i got output.mp4 with duration 9.846. Where is my error ? Why output video longer than source ? (9.846 sec and 9.800 sec).
