Hello, This is Hillary.
I have experience in FFMPEG. I had built an video player application with ffmpeg, in which I experieced to cut video with timestamps and add watermarking, etc. And I can provide some image processings.
Also I have skills in c/c++, qt and python and others too. In the future, If you allow me, I can provide the beautiful UI implementations.
I am very interested in your project and I want to discuss more details about your project.
Regards.
