[FFmpeg-user] Write audio frames without decoding/encoding

I'm using FFmpeg programmatically in C. I currently take a .mp4 file, get
the video frames, alter them, and save them to a new .mp4 file. I would like
to add the audio from the original .mp4 into the new one, unmodified. 

Is it possible to read an audio packet and then just place that packet into
a new file without having to decode/re-encode it?

Can I just take the raw data from the AVPacket (the samples?) and write them
to my new file?

I'm having difficulties getting this to work, so I was wondering if it is
possible. Any help is much appreciated, thanks.
