> including right click to save This only works for video tags that load a single webm/mp4 file. If it's using more complex chunked/streaming/mediasource delivery mode then you can't save the whole video because it's driven by javascript that might only keep a tiny slice of it loaded at any given time and not a single downloadable file. It also auto-negotiate quality and serve you a reduced version, which is probably not what you would want if you're downloading it. Then you need browser addons or tools like youtube-dl to get the whole thing.
