Hi.
I have experience in working with ffmpeg and using h264 codec (x264). I have done muxing/demuxing, custom IO contexts, decoding and encoding works.
Also I have worked with OpenCV libraries and have a good understanding of OpenCVs internal data structures.
Have you decided any UI frameworks to use in this POC. I would suggest to look at Qt as I have successfuly used it with ffmpeg and OpenCV libraries.
Hope we can work together on this on.
Thanks.
