Dynamic Youtube VideoBar

I have a blog with many subjects (music, cinema ,…)
I installed the plugin Dynamic Youtube VideoBar and working properly but it can only show the videos that are looking for the Search Keyword.My intention is that the videos are changing as the theme for the post. If I talk about movies appearing on video films, if I talk about music appearing videos of songs …
Something similar to what the advertising that Google Adsense depending on the topic puts some ads or others.

Can anyone help me or tell me another plugin that makes what I’m looking for?
