How to make Dash 'behave' like Youtube?

[yoann2lose]

Hello to all people reading this, I'll try to do long story short but can't promise anything to you.
So a part of my project was to study the behavior ( through emulation of Youtube on VMs ) of Youtube's algorithm. Thus I got some results I would like to modify/improve the latest Dash's version in order to be able to use it between two VM on an internal network in order not to have to use Youtube which has unpredictable behaviors such as the congestion of Youtube's network, my company's network etc.

The goal is to use an apache server on one of my VM and the other one plays the role of a client asking for a video and by tickling with source code I want to see the kind of behavior I saw on Youtube's. I already identified some of the lines ( mainly defaults arguments or so ) to modify hoping for it to behave like Youtube but not is the problem :

I already have what I call a job, using 2.4.X version of Dash with 20 lines addition in order to get the data I am interested in and it goes to one of my VM and I can analyse it then.
BUT

Now that there are 4.X versions, and I guess the compatibility between them isn't obvious, I first tried a wget command on my VM which gave me some of the package I guess are important and I replaced them whenever I could on the 2.4.X version.
The results is of course it doesn't work but I am totally not confident about my way of doing and surely how to start with all this.
Putting hands on a close to 10 years dev application like Dash is very disturbing for me.

I am totally at your disposal for further information, I tried to be clear and yet not exhaustive ( would have taken me 10 pages I guess ).

Thanks for your future help,

Cheers from France,

Yoann
