I wonder if you mean this:
add_filter( 'oembed_dataparse', function( $return, $data, $url )
{
// Target only 'video' type:
if(
is_object( $data )
&& property_exists( $data, 'type' )
&& 'video' === $data->type
)
{
// do stuff
}
return $return;
}, 10, 3 );
where we target the video
type response from the oEmbed service, before it’s cached in the post meta.
