Hi, I'm a Delphi developer with more than 30 years of experience (yes, since the times of Borland's Turbo Pascal). The past 20 years I was full-time employed by two international organizations (IATTC, in San Diego, CA, USA, and the United Nations, in Victoria, Seychelles). I'm currently retired, but like to stay busy taking projects I find interested as a freelancer.
To be honest, I don't have direct experience with the Open-CV wrappers to ffmpeg, but I have used the FFVCL wrapper. I don't think using the Open-CV wrapper would be much more complicated, although it will involve some reading/learning/trial-error on my part. If you don't find anyone with the required expertise, I'm sure I can be of help.
If you are interested in my services, please contact me through a PM. We can discuss options regarding what wrapper to use, and I can provide a copy of my CV for you to check references/experience.
Best regards,
Marco García
