[FFmpeg-devel] [PATCH 1/2] avcodec/liblc3: Add encoding/decoding support of LC3 audio codec

> LC3 is like a subset of LC3plus, but also adds 7.5ms frame duration.

> Moreover, LC3 and LC3plus declares both the 10ms frame duration. It's
> impossible to distinguish such a stream as LC3 or LC3plus.
> The main difference between the 2 codecs are licenses:

> profile claiming it.
> - LC3plus can be used anywhere, but is under license fee.

> So it makes sense to me to cover both as LC3.

Thanks for the convincing explanation.
