With that, ffmpeg output a movie, and the channel layout was correct - it plays. I added SDL and made ffplay, and huh, yup, plays it.

My best lead now is probably the note ffmpeg made:

> Seems stream 0 codec frame rate differs from container frame rate: 30000.00 (30000/1) -> 29.97 (30000/1001)

It may well be timing related, and it seems sure it's in my app. I guess that channel layout is emitted but doesn't prevent anything.
