I have been looking for a non plugin solution where a user can upload a video, say, something from a site like http://www.coverr.co/.

When the user adds the video via the featured image link in the post/page editor, a static image will be generated and used as the featured image, but when the post is viewed, the title of the post is displayed on top of the actual video being played.

Hope that made sense. So far I haven't found anything. Ideas?

  • I can clearly see the link, but here it is again [coverr.co] (coverr.co) a site like that.

  • No, it was not the problem with the URL, but I thought there are other distinct sites like this one from where you are doing things...

  • The biggest problem with this is that you're asking WordPress to take a picture of the first frame of whatever video it's pulling. Sites like youtube already have these images set where you can pull them from video ID like this and set them in WordPress like this. This is probably too hefty for a simple code snippet and better suited as a Plugin. An answer may not be feasible and the question ends up as too broad.

  • @Howdy_McGee An answer is always feasible amigo, some how, some way. The question still remains simple: When the user adds the video via the featured image link in the post/page editor, a static image will be generated and used as the featured image, but when the post is viewed, the title of the post is displayed on top of the actual video being played. Thanks for the info though, its greatly appreciated

You can work around if you have time.
- Install http://ffmpeg-php.sourceforge.net/
- Create a custom meta field (upload field - you can use a plugin)
- In your template or loop, get retrieve the uploaded video URL and assign it to a variable
- Use the following function to generate an image from the retrieved video (I am not entirely sure if it will work and if it will not slow down your website)

$frame = 10;
$movie = 'test.mp4';   // this could be the variable from the vid url
$thumbnail = 'thumbnail.png';

$mov = new ffmpeg_movie($movie);  
$frame = $mov->getFrame($frame);
if ($frame) {
    $gd_image = $frame->toGDImage();
    if ($gd_image) {
       imagepng($gd_image, $thumbnail);
       imagedestroy($gd_image);
       echo '<img src="'.$thumbnail.'">';
    }
}
