Play a youtube video bu using shockwave flash object and youtube api

I built a software in winforms and I want to insert to my software 1 video guide. After a few tests I managed to run videos from YouTube with shockwave flash object and youtube api. My questions are:

1. Is there a difference between the two if I want to run only 1 public video (Without user authentication)?


2. Is it permitted under Google's ads (youtube ads) policies?
