Nit: should be nb_channels (more meaningful, consistent with
nb_samples) or channels (consistent with AVCodecContext)?

I'm not still sure it is a good idea to propagate the info to lavfi
(since we may require that the channel layout is always set inside the
filtergraph), but this patch seems useful on its own and shouldn't
hurt anyway.
