[FFmpeg-user] Adding Audio to a video without re-encoding?

[Meino.Cramer at gmx.de]

Hi,

I have an video file (h264), which is without audio. I want to add
music to it and have an audio file of the correct length.

Is it possible to add that audio file to the video file without
re-encoding one or both files?
And if yes, how can I accieve this?

Best regards,
mcc
