Summary of the bug:
Ffmpeg code does not encode 48000 kbit or 56000 kbit and it does not
decode those properly, even though it says it should
https://www.ffmpeg.org/doxygen/0.11/g722_8c.html
It is not gapless, at least on decoder side, and even more funny reference
ITU code does not decode it properly. https://github.com/openitu/STL
Oh and you need to force 16000 Hz before encoding G722 in ffmpeg, another
bug. See e.g.
How to reproduce:
Complile https://github.com/openitu/STL/tree/dev/src/g722 and compare.
Also see
https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/2277 it
dropped ffmpeg implementation.
Patches should be submitted to the ffmpeg-devel mailing list and not this
bug tracker.
