using opencv for this might not work at all
usually, embedded videos on web pages do not point to a stream directly, but load some player software, which does the job under the hood. if you want to jump around there, it has to preload the resp. parts (and some in front of it) for decoding (you cannot just grab a single frame).
as long as ffmpeg can't do it, VideoCapture can't do it either.
opencv, being a computer-vision library, will also strip any audio.
