Hi ****,
please can you help the ***?
with this commandline I put an audio track to a mp4 that don't have any audio:
ffmpeg.exe -y -i source.mp4 -i audiotrack.wav -vcodec copy -c:a ac3 -b:a 256k -aspect 16:9 output.mp4
Now I wonder: and for audio replacement?
and IF the source.mp4 have jet any audio track (or audio tracks) can I modify the commandline so that the only audio that videoANDaudio.mp4 become to have, is audiotrack.wav? FFMpeg have to delete all audio track inside source.mp4 (if it have any audio track) and add the only audiotrack.wav
is it possible?
thanks

you need to use -map
Code:ffmpeg.exe -i source.mp4 -i audiotrack.wav -map 0:0 -map 1:0 -c:v copy -c:a ac3 -b:a 256k -aspect 16:9 output.mp4
