I can do this for avi in seconds, but not mp4. I can't even find a frontend that will do this (just re-muxing in the audio over the old audio in the mp4). I've tried changing the syntax a little each time, but it always returns the same stream (so -map 1:a:0 = -map 1:a = -map 1, etc.).Ĭl string: "ffmpeg -i video-01.mp4 -i audio-01.m4a -map 0:v -vcodec copy -map 1:a -acodec copy newvideo-01.mp4"Īm I missing or overlooking something in the ffmpeg help? or doing something blatantly stupid?Īll of the audio was recorded at different distances (and therefore, levels), so the normalization is absolutely necessary.
