Before starting doing any changes I recommend to import project into IDE and then perform any changes from there.
To successfully run application locally you have to change first line in stream method inside Streamer object
and change value of path variable. I have added small .mp4 file to repository, so you can use it as test video.
Example
val path = "path/to/file" => val path = "/path/to/project/test-video.mp4"
