i have been searching for a while but no luck. you should search one by one.
becuase many containers support variety of codecs, but unfortunately, ffmpeg dose not support that perfectly. even if you can transcode, you can't playback it.
following link is which containers support what codecs. remind that this lists are not matched with ffmpeg perfectly.

following lists are my tested results in ffmpeg 2.2, which containers support h264/mp3 codecs. perhaps this is what you want :)
H264(libx264) available containers : mp4, flv, ts, mkv, mts, mov, 3gp, 3g2
mp3(libmp3lame) available containers : mp4, wmv, flv, avi, mkv, mpg, mts, mov
