Help me modify code for videos in homepage posts

Hi,

I would be very grateful to the WP community if someone can help me modify some code I found this forum that enables videos to be displayed on my homepage.

I have a basic blog style site with recent posts listed on the homepage. The problem I was having is videos would not show up on the homepage because you can’t assign a video as a featured image. I did not want to use thumbnail images for videos. I want users to be able to play videos without clicking through to a post.

So I found some code on this forum that has done an amazing job of doing just that. If a video is embed in a post it will automatically post the video where the featured image would usually be.

But now I have ran into 2 problems with the code…

1) If I have more than 1 video embed it will not show any videos and only show the post title on my homepage.

2) If I try to add a featured image as a thumbnail of the video for my rent post sidebar widget, the code will show the featured image AND the video below it.

I need to be able to assign a featured image in the post that will show as post thumbnail only on sidebar if possible. I don’t want the thumbnail to show above the video on the homepage or within the post.

Then secondly I need the code to allow more than one video in a post and make it select the first video in the post as the video that gets displayed on the homepage.

Here is the code from my features.php.

/** Add Video Homepage */
    function catch_video() {
      global $post, $posts;
      $first_vid = '';
      ob_start();
      ob_end_clean();
      $output = preg_match_all('/<iframe.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
      $first_vid = $matches [1] [0];

      if ($output == '1') {
      echo '<iframe width="630" height="350" src="';
      echo $first_vid;
      echo '" frameborder="0" allowfullscreen></iframe>';
      }
    }
