This is too old.

As said, why do want to change "mov" to "mp4"?

You can remux this stream with -vcodec copy

PCM audio is only supported in mov, not in mp4 (this has
nothing to do with FFmpeg, the limitation is inthe mp4
specification), you have to convert to a supported audio
format, use for example -acodec aac -strict -2 (fdk is a
better encoder, libvo-aac is not).
