issue in patch #31

seems that

the commit of b21fc4f on 7.x-3.x

( http://cgit.drupalcode.org/video_filter/tree/editors/ckeditor/plugin.js?... )

caused a missing else statement

in line 124

leading the autoplay to work in chrome even if not checked

check patch #31 (https://www.drupal.org/files/issues/video-filter-modal-autoplay-2335169-...)
it includes what's missing

if (data.autoplay) {
+          str += ' autoplay:' + data.autoplay;
+        }
+        else {
+          str += ' autoplay:0';
+        }
