Comment (by amc1804):

 I wish I could do the reverse: copy aac to aac_latm without recoding.
 Why?  Because my !TiVo can pull H.264 video and AAC audio from my PC, but
 only when they're wrapped in mpegts and latm.  My camera produces them as
 an mp4.  The conversion could in principle be done with no recoding, but
 currently with ffmpeg I have no choice but to recode the audio (to ac3 for
 example), because ffmpeg cannot produce latm.
