Wordpress and automatic embedding of Youtube videos

Question

YouTube

Good afternoon, I have the following task:
Before the YouTube video player, insert the title of this video directly.
The video is inserted automatically using the tools of Wordpress itself. I searched through all the class-oembed.php code and the rest, but I did not find the place where the line is formed that displays the player itself.
Please help.

Answer 1

I didn’t quite understand what the title was, but maybe this filter will help: “embed_oembed_html”. Located in /wp-includes/class-wp-embed.php Embedding a
video using the "[embed]" shortcode?

Answer 2

You can read goo.gl/cgX78h (You can deal with the YouTube API)
But in general, I would look in the direction of plugins then. Or you can write your own.
