String command =
'-y -i "$inputVideoPath" -i "$bgMusicPath" '
'-filter_complex
"[0:a]volume=1.5[a0];[1:a]volume=0.1[a1];[a0][a1]amix=inputs=2:duration=first[aout]"
'
'-map 0:v -map "[aout]" -c:v copy -c:a aac -b:a 256k -shortest
"$outputPath”';
I want the background music to be clear but not overpowering, and the user’s
voice to remain clean and prominentin the final output.
Can you please guide me on how to improve this? Any suggestions would be
greatly appreciated.
