the sound start is cut and audio is ahead even more with your command line.
ffmpeg -i mjpeg.avi -qscale 2 -strict -2 -vcodec mpeg4 -acodec aac out.mp4

Hello,
I am trying to convert Canon MJPEG to MP4 (h264/AAC) but after conversion, the
start of the audio is cut and sound is not synchronized.
ffmpeg -i mjpeg.avi -c:v libx264 -preset slow -crf 13 -pix_fmt yuvj420p -c:a
libfdk_aac -b:a 192k output.mp4
or
ffmpeg -async 1 -i mjpeg.avi
