Please help with embedding videos

[greensavage2000]

For the life of me I can't embed vids. I'm using an Android phone. I go to YouTube and in my options I pick " request desktop site". The embed button isn't there when I click "share" if I use the app. I click share and then the "embed" button. I copy the code in the box which is highlighted in blue. I come here and paste it and get know embedded video. Here's an example.

<iframe width="560" height="315" src="https://www.youtube.com/embed/B9FzVhw8_bY?ecver=1" frameborder="0" allowfullscreen></iframe>

I copy the embed code from videos here and it looks like this one with a different video code after where it says "embed/". If any one can help me understand what I'm doing wrong I would greatly appreciate it.
