You'll need to first convert cv::Mat to AVFrame, some code like
http://stackoverflow.com/questions/35907094/converting-cvmat-image-from-bgr-to-yuv-using-ffmpeg
Then encode the frames using codec libvpx and mux using format webm (take a
look at https://www.ffmpeg.org/doxygen/3.2/muxing_8c-example.html which is
kind of old though.)
