Your ffmpeg version cannot produce top quality aac using encoder aac instead of libfdk_aac

I guess this is just a non urgent feature request. I am using this container and it is working very well but I keep seeing this error. I thought maybe you would update the deployment to include this libfdk_aac. Thanks.

That would require compiling ffmpeg with fdkaac, which I don't want to do in this image, but I believe the official Dockerfile includes it: https://github.com/sandreas/m4b-tool/blob/master/README.md#docker
