How can i download this video, which is splitted in "corrupt" m4s-files?

Hi,
i tried to download Videos from this site, here is an example;

https://www.pietsmiet.de/videos/52768-rimworld-uncut?playlist=2899-rimworld

You dont need to register/pay to see the Videos, there is no authentication. I think there isnt even a sessiontoken

The videos are splitted in short m4s-files. The links seem to be generated clientside.
I cant even (batch)download the single segments to later join them together, because all files are corrupt.
Also, there is sometimes randomly a request for a "mp4"-segment instead of a "m4s"-stream-segment.
The website is custom-made with the Laravel-Framework

Here is an example of an segment-url. Im not sure if the part between the "," is the "base-url" for the stream-segments, but that part doesnt change if i play the same Video in different tabs.

What i tried:
youtube-dl/ffmpeg
Network-Streams from VLC-Player
JDownloader
Different extensions ( i.E. VideoDownloadHelper, just gives me corrupt files and doesnt even pick up all segments )
Network-Sniffer to see if there are any other requests i cant see in developer-console
Some stream-sniffer-programs that also analyze all traffic and try to get the streamfiles

Is there a way to download Videos from this site? If it isnt possible to download the complete video, why are the downloaded stream-segments always corrupt and cant be merged to a single file?
