I am unsure if this is good enough...
The service mooma.sh gave me the following result: Craig Riley - Hangin' Out (alongside another useless result).
Craig Riley - Hangin' Out sounds very similar to the song on the video. I had to listen multiple times to make sure I was not listening to the same song.
I believe in Craig Riley - Hangin' Out the melody uses strings instrument (mandolin or guitar) while the melody on video sounds more like piano. In addition, the melody does not match, but it has similar structure (see notes) and the same tempo. The percussion sound identical.
Listening to the music in the other videos on the channel you can notice that you never hear the song properly die, it just fades off at the end of the video, regardless of the lenght of the video. I conjecture they are looping a section of the song. Although I have not done a proper analysis of this, which is off-topic on this site anyway.
I speculate that the songs could be reinterpretation of the same original, or perhaps they are improvisations to a generic percussion track or samples. However, that's just my opinion.
