Improve ffmpeg command for MKV to MP4 for iPad?

Question

I have many MKVs made from DVDs and BRs by MakeMKV that I converting to MP4 so I can play/stream on my iPad Air. I now use this command for converting my MKVs to MP4:

    ffmpeg -i input.mkv -strict experimental -map 0:0 -map 0:1 -map 0:2 -map 0:3 -c:v copy -c:a aac -b:a 384k -c:s copy output.mp4

I have video, 2 soundtracks and 1 subtitle. I want as little loss as possible, both in picture and sound. I also need all the subtiteles and soundtracks in the MKV (usually 2 soundtracks and 1 subtitle).

I have downloaded the 32-bit static ffmpeg build from zeranoe. I'm new to ffmpeg, so I don't know how to get libfdk_aac, which I don't believe is in the zeranoe build? I have read that libfdk_aac is the highest quality.

I'm also going to stream this to the iPad Air, so keep that in mind. It has worked good so far :)

Any ideas to make this better?

How is this question different than [ffmpeg: Converting MKV to MP4 lossless](http://superuser.com/q/758080/110524)? Also, you should always provide the complete console output that results from your `ffmpeg` command. — llogan, May 25 '14 at 22:36
@LordNeckbeard The diffrence is that the last question was about getting a command the works. I have found a command that works, but there is probably improvements to be made in my command :) Sorry, but I don't know what complete console output means, and how I get it. — Striky, May 26 '14 at 07:59
When you run your ffmpeg command it will output a bunch of text in your console. That's what I'm looking for. — llogan, May 26 '14 at 16:48
@LordNeckbeard Posted the output in a new answer down on the page. Don't know how to make it look good, just copied and pasted it. — Striky, May 26 '14 at 18:20

If you use copy mode for audio and video codecs (-c:v/-c:a copy) there will be no quality loss, so you cant improve it, it will be the same. Also you can't use other codecs like aac if input is not aac (it's all about copy mode).

I can't copy audio, as Apple does not support DTS. – Striky May 25 '14 at 21:44
I know if I just copy and chang container, there will be no loss. However, I need to change the container to mp4, and soundtracks from DTS because Apple don't work with those containers and codecs. And as I say, i'm not looking for lossless (since I need to decode the soundtracks), but I want as little loss as possible :) With ffmpeg I converted ac-3 (MKV) to acc (MP4). – Striky May 26 '14 at 09:23
