I have 3 consecutive FFmpeg commands that will customize the volume of an audio, customize the volume of a video, and amerge
audio and video to a final output.
First command, edit volume level of a mp3 File
ffmpeg -i music.mp3 -vol 100 music2.mp3
Second command, edit volume level of a mp4 file
ffmpeg -i video.mp4 -vol 200 video2.mp4
Third command,merge music2.mp3
andvideo2.mp4
ffmpeg -i music2.mp3 -i ruby.mp4 -filter_complex \
"[0:a][1:a]amerge,pan=stereo:c0<c0+c2:c1<c1+c3[out]" \
-map 1:v -map "[out]" -c:v copy -c:a libfdk_aac -shortest video2.mp4
Is there an easy way to simplify and breakdown processes into just one process/command?
I've tried this one, but not working:
ffmpeg -i music.mp3 -vol 100 -i video.mp4 -vol 200 -filter_complex \
"[0:a][1:a]amerge,pan=stereo:c0<c0+c2:c1<c1+c3[out]" \
-map 1:v -map "[out]" -c:v copy -c:a libfdk_aac -shortest output.mp4
