ADDITIONAL INFORMATION
Comment 1 caulier.gilles 2022-12-06 04:10:24 UTC 
Did you use ffmpeg 5 API. If yes, only next digiKam 8.0.0 will be compatible with ffmpeg 5. digiKam 7.9.0 only support ffmpeg < 5.

Hi!  Yes, I did.

I installed replaced the development package for FFmpeg5 with ffmpeg4 per your comment, and it now compiles and runs!

Thanks!
