[SOLVED] Video Preview

Hello, I would like to include a video in the module "Video Preview" in the "Musican ,, Theme.
I have already installed and activated the ,, All Videos Plugin ,,
uploaded a video via FTP and copied in the path instead of the existing path, I tried the same with a youtube video:
<div class = "responsive-video">
<iframe width = "560" height = "315" src = "" frameborder = "0" allowfullscreen = "">
</ Div>

However, the video is not displayed, what am I doing wrong?
Thank you for your answer

Hi there,
you dont need a plugin to activate the video.
Just insert the iframe from Youtube and insert the code into your module.

<div class = "responsive-video">
<iframe width = "560" height = "315" src = "

" frameborder = "0" allowfullscreen = "">
</ Div>

Problem solved.
