So it will happen only after the release 5 of FFMpeg right ?

Not sure. There were people who wanted the merge the channel layout api before the release.


Is it possible to merge it, and we can rework it after the new API is
released ?
Patches are related to IMF (new format) patches, and if FFmpeg can
accept
IMF without MCA support it will generate a lot of errors in audio
mapping.
So even if it's not performant for now, is it possible to imagine to
merge
patches and rework after ?

I suspect this might create problems for the people writing the
reordering API

It is not matter of performance, we should not introduce a hack such as reordering PCM channels in a demuxer if there is a better solution on the horizon.

If this is urgent, we could merge it without reordering support.

Marton
