Concat MP4 files without transcoding to mpeg

1. Use the h264_mp4toannexb bitstream filter to convert the mp4s (video steam only) into the AnnexB bitstream format

   ffmpeg -i input1.mp4 -vcodec copy -vbsf h264_mp4toannexb -acodec copy part1.ts
   # repeat for up to inputN
   

2. Concat the files using cat
