There is a Google Chrome extension called "Video DdownloadHelper (VDH)" with which I can download the video but only in two separate files - one video file and one audio file - that I have then to combine using another software called Avidemux; VDH in the Detail section for the video shows me the mediaManifest, in the case of the above video URL the link of the mediaManifest is:

 https://vas-v4.p7s1video.net/4.0/playlist.m3u8?x=01&y=myhBHrDNNfEQB1qjyId2ubWMGxs3o6y_fQyvoJddsUT--1095iJS-vy2OxX7LvhgskRikJYrMbB6MCgqY94EChbt1WVRHlJIdsJa3Rqd5zbHQdZWcJDcM6i9-KMPs4c2-JyIZWO_K_h9mXuk_jR8i3-MK2sJkXofsMbslQEXBsHlPG_tnTw4JiIeokqwB2ctieCRV6Up2NzkdqHpNMuWl0S16RTkdW_wm55-vuSROx2h-QlJZkJDaszCm8eE-hspS6jm--yxuc7mGKunMchw6mLAtdZELYFn5Vo2OwZ_PRZlQx0htHiOv6KFt6fPSziHhLM4Tcy0sOznM8tNlHHZAse6zsCb5q8zosAUlAPAAL3QpgqbfIsXOnd9VDVAMnzGnNczE0Dcp-HZ5M0hhFMR-Q

If I copy this link and enter it in a new tab, a file called "playlist.m3u8" is being downloaded which contains all segments of the video; each segment is 6 seconds long; when I double-click on "playlist.m3u8", the video is being automatically opened and played on VLC - but still without audio; of course it would be very comfortable if it was possible to download the video "ready to watch" including the audio with one simple klick!
