Re: FFmpeg (5.0) since the "Lorentz"<https://ffmpeg.org/download.html#release_5.0> release...

Unfortunately I can't run any tests at the moment so perhaps you can advise.
The release information states that the old encode/decode APIs were replaced with an N:M-based API. Does this affect production of Frame MD5  - would FrameMD5s generated by releases from Lorentz onwards produce different values from older versions of FFMPEG when run against the same AV files?

Many thanks,
Ian Henderson
