That is just what I said: in lavfi, the channel layout is mandatory.

If the channel layout is set and valid, it works.

If the channel layout is not set but there are <=8 channels, then ffmpeg
"guesses" a channel layout, and it works (more or less).

If the channel layout is not set and there are >8 channels, then the channel
layout stays not set, and lavfi fails.

And lavfi is now mandatory for ffmpeg when transcoding, even if the filter
graph has no filters.

Does this answer your question, or did I misunderstand it?
