#32714 closed defect (bug) (fixed)

oEmbed of m.youtube.com links don't render

Reported by: undergroundnetwork Owned by: wonderboymusic
Milestone: 4.3 Priority: normal
Severity: normal Version: 3.9
Component: Embeds Keywords: good-first-bug has-patch

When a user is using a mobile phone to post to Wordpress, and they copy and paste a YouTube URL, YouTube changes the URLs of it's videos when accessed on a mobile phone by adding an m. before the URL, like: https://m.youtube.com/watch?v=yfUflij74P4

This results in Wordpress not recognizing that it is a YouTube URL and oEmbed does not render as a result.

This causes problems when using Press This as Press This grabs the URL which has an m. in it. This is a problem when a user has copied a YouTube URL on their phone (via the URL address bar, or the share menu on most phones) and they try to paste it into an article, because, again, YouTube puts that m. in the URL.

In order to make this work, perhaps a filter that removes the m. from YouTube URLs would help and the URLs could then render.

I have attached a patch for wp-includes/class-oembed.php. It should now handle both www. and m..
I have found that code for PressThis in wp-admin/includes/class-wp-press-this.php already handles both www. and m. YouTube site.

  • Resolution fixed deleted

This fix seems to no longer work, the mobile YouTube links no longer rendering again. This link does not render for example:


Perhaps YouTube changed the format of their links?

Replying to undergroundnetwork:

This fix seems to no longer work, the mobile YouTube links no longer rendering again. This link does not render for example:


Which version are you testing? Your link seems to work for me:

var_dump( esc_html( wp_oembed_get( 'https://m.youtube.com/watch?feature=youtu.be&v=peVH0k0Hisc' ) ) );
// string(189) "<iframe width="660" height="371" src="https://www.youtube.com/embed/peVH0k0Hisc?feature=oembed" frameborder="0" allowfullscreen></iframe>"

I'm running 4.2.4, the first test was on an iPad using Press This.

Oh wait! Is this not supposed to work until 4.3?? Did I just screw up?

If it is supposed to work, here is another example, I just took this YouTube link:


Pasted it into my new post and again it doesn't render.

I just ran it on a clean site, twenty12 theme, no plugins, but this link will render:


Again, if this is not supposed to work until 4.3 I apologize for reopening this again.

In 41712:

Embeds: Remove the external oEmbed tests for YouTube.

These tests no longer test anything that WordPress core has control over. YouTube now serves everything
over HTTPS by default, so the tests for #23149 will always pass, and the tests for #32714 aren't testing
anything that core has control over.

Tests for the responses from oEmbed providers has been attempted and reverted in #32360.

See #42076, #32714, #23149
