How to record stream from this site?

[godlydevils]

So I bought this Game Leap's account, and I want to save their vids,

so for sake of example

https://www.game-leap.com/courses/do...les-of-winning

Here, I can download all vids by grabbing the m3u8 link and pasting to vcatcher

Except the third one named "Approach to the game"

Now the thing is they are Basically free vids, but the whole website has stream like that of 3rd vid

for eg
If I try to download the second vid

Link to m3u8:
https://videos.game-leap.com/HJk5Ag_...00k_1080p.m3u8

I can download for sure

But the third vid

https://videos.game-leap.com/ryetFbO...00k_1080p.m3u8

Just cannot download, in vcatcher, window shows some error and goes away in blink of an eye

if someone can teach me how to get vids like that downloaded, I'd appreciate that,

P.S. I'm formerly ffmpeg user, so I won't have problem understanding that.
