You can use XML format instead of JSON (and, if you need of JSON format for any reason, re-convert it):

$url = 'https://www.youtube.com/oembed?format=xml&url=https://www.youtube.com/watch?v=EeVIPLzui7M';
$xml = simplexml_load_file( $url );

echo $xml->author_name . PHP_EOL;
echo $xml->width . PHP_EOL;
echo $xml->thumbnail_url . PHP_EOL;
echo $xml->thumbnail_width . PHP_EOL;
echo $xml->provider_url . PHP_EOL;
echo $xml->type . PHP_EOL;
echo $xml->height . PHP_EOL;
echo $xml->author_url . PHP_EOL;
echo $xml->version . PHP_EOL;
echo $xml->provider_name . PHP_EOL;
echo $xml->thumbnail_height . PHP_EOL;
echo $xml->title . PHP_EOL;
echo htmlentities( $xml->html ) . PHP_EOL;

will output:

If you desire data in JSON format, use this:

$xml  = simplexml_load_file( $url );
$json = json_encode( $xml );

Output (prettified):

    "html": "<iframe width=\"480\" height=\"270\" src=\"https:\/\/www.youtube.com\/embed\/EeVIPLzui7M?feature=oembed\" frameborder=\"0\" allowfullscreen><\/iframe>",

Always use functions for debugging

json_last_error();
json_last_error_msg();

In your case the output is:

int(4)
string(12) "Syntax error"

That's why printing 'null' gives you nothing.

For more details you can use online validators like a http://jsonlint.com

THE FIX:

Change every unicode char from the response with uppercase 'U' into the lower case 'u'

For example: '\U0001f60e' => '\u0001f60e'

Just opening https://www.youtube.com/oembed?format=json&url=https://www.youtube.com/watch?v=EeVIPLzui7M# in my browser displays a JSON syntax error (since I have a browser extension to render JSON).

json_decode is returning NULL because what you are passing into it is not JSON. Presumably this is due to a bug on YouTube's part.
