Ask for help to take the first steps

Dear All,
I have just come across the Alcinoe library which contains some very exciting features. After the installations I was able to launch the demos on Android without any further difficulty, so I consider the installation to be successful and complete.
I wanted to create a completely new project that includes Alcinoe FMX controls, but not by cleaning up the existing demo, but by starting from a new project.
Unfortunately, however, this is beyond my knowledge. For example, I tried to add a simple video player to a blank form. So for Android, I searched out the file com.google.android.exoplayer-exoplayer-core-2.19.1.jar which I added to the Libraries and added an AlVideoPlayerSurface control to the form. In Project Options, I set the search paths and then I turned it on. The translation was successful, however I got a Segmentation Fault after the app started.
I'm sure I missed quite a few important steps, but unfortunately I can only find descriptions in the descriptions and source files that are not completely clear to me, I would probably need more knowledge.

I would be very grateful if someone could help me with a description of exactly what steps are needed to build a working project using Alcinoe's FMX controls (or at least the video player) from a new project.

I am currently working on Athens 12.

Thanks in advance for any help!
