Cause you tell it to do so:

--merge-output-format mp4

Correct command is -x --audio-format aac to download audio. --audio-format is only used for extracting audio - you can't just convert audio alone and mux with bestvideo.

Maybe it would help to read the report before answering and closing it.

youtube-dl should generate an mp4 file with avc video and aac audio, as usual.

it does not do that because it downloads opus and does not convert it.

You did not tell it to convert (-x) that's why it followed default flow to download bestvideo+bestaudio. At the same time you've specified --merge-output-format mp4 that forces mux container to mp4 that is incompatible as merge targed for mp4+webm.

@dstftw commented on GitHub (May 18, 2016): You **did not** tell it to convert (`-x`) that's why it followed default flow to download bestvideo+bestaudio. At the same time you've specified `--merge-output-format mp4` that forces mux container to mp4 that is incompatible as merge targed for mp4+webm.

The closest thing you can do in order to achieve

video with AVC video codec, AAC audio codec, and both packed into mp4

(you had to mention this in the OP post in the first place since it's not possible to decipher whether your intention was actually to download audio, convert it, download video and mux them or just download audio and convert it or whatever else, needless to say you did not even follow new issue template and provide all information we require for a report).

~~is to download formats separately (-f bestvideo[ext=mp4] and -f bestaudio -x --audio-format aac) and mux them by hand~~
aac is actually available as original format without conversion so plain -f bestvideo[ext=mp4]+bestaudio[ext=m4a] should do what you want.
