Message: <blockquote data-quote="Kevin" data-source="post: 1546531" data-attributes="member: 21">Yeah, it looks like an update to the YT URL parsing over the years may have broken it.  The function [icode]matchCallback[/icode] in /XF/Bbode/Helper/YouTube.php looks for the 'list' parameter and if found saves it as part of the matched media ID (so a URL like [icode]https://www.youtube.com/watch?v=a01QQZyl-_I&list=PLmXxqSJJq-yXrCPGIT2gn8b34JjOrl4Xf&index=10[/icode] gets turned into [icode]a01QQZyl-_I, list: PLmXxqSJJq-yXrCPGIT2gn8b34JjOrl4Xf[/icode] for the matched ID. That seems to work fine everywhere in XF since the video IDs are recognized & parsed as needed to embed the YT code and is why the actual video still plays in XFMG. With XFMG when retrieving the thumbnail the function [icode]getTempThumbnailPath[/icode] in /src/addons/XFMG/EmbedData/YouTube.php seems to be looking for a video ID with a ":" colon in it and, if found, to parse out just the actual video ID [icode]a01QQZyl-_I[/icode] when creating the thumbnail URL.  So the XF devs know that the media ID could have extra data in it and to work around it to get the real ID. But in the example of [icode]a01QQZyl-_I, list: PLmXxqSJJq-yXrCPGIT2gn8b34JjOrl4Xf[/icode] it doesn't get matched in the regex so the URL requested ends up as [icode]https://i.ytimg.com/vi/a01QQZyl-_I, list: PLmXxqSJJq-yXrCPGIT2gn8b34JjOrl4Xf/maxresdefault.jpg[/icode] instead of [icode]https://i.ytimg.com/vi/a01QQZyl-_I/maxresdefault.jpg[/icode] so it of course fails. My guess is that the regex needs to be updated.  Maybe something like [icode](.*)(\,\.*)[/icode] to parse on "," instead of the colon but this is where the XF guys know what they're doing far better than I so I'll wait & see what the patch fix looks like.  <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big grin    :D" loading="lazy" data-shortname=":D" /> </blockquote>
