So it is.

Sounds good.

I've done a quick and dirty solution at packman now. I've splitted out 
the libs into a mjpegtools-lib package and readded mjpegtools 1.9.0 as 
mjpegtools19. Both library packages (mjpegtools-lib and mjpegtools19-
lib) can be installed without conflicts. Packagis having problems to 
build against mjpegtools 2.0.0 can use BuildRequires: mjpegtools19-devel

Thanks for your engagemnet.

Sorry I can't do much on this topic. My skills in c programming are not 
so great and I've to big projects @work, so my sparetime is extremely
