You certainly *can* remux h.264 video and AAC audio into a transport

ffmpeg -i 01.mp4 -c copy -bsf:v h264_mp4toannexb 01.ts
ffmpeg -i 02.mp4 -c copy -bsf:v h264_mp4toannexb 02.ts
ffmpeg -i "concat:01.ts|02.ts" -c copy -bsf:a aac_adtstoasc output.mp4

creating those intermediate files. Really, with recent ffmpeg you should
only use the concat protocol if your input files are already in one of the
formats that supports file-level concatenation (like mpeg, vob, or ts
