Added a youtube video in a blog entry:

text before video ...
[embed=videolink]{"video":"https://www.youtube.com/watch?v=AAAAAAAA";,"width":"400","height":"300"}[/embed]
Text after video ...

Calling the blog entry in the browser (Chrome 38) displays the text before and after, but not the video. There is a white blank field in between the text before and text after.
Video link works fine if I copy & paste the URL.

Using Joomla 2.5.x with pagespeed.

Apache logs do not show any errors.

Hint / advise: welcome!
