I’m getting all videos using the function below and it’s working fine. Now I want to get the videos Poster Image (Thumbnail Image) from that video. How can I get the video Image as thumbnail? I’ve also tried to get thumbnail by this function but It’s not working 

    $page_id = 659; 
    $page_data = get_page( $page_id ); 

    if (has_post_thumbnail( $page_data->ID ) ){ ?>
    <?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $page_data->ID ), 'single-post-thumbnail' ); ?>
    <img src="<?php echo $image[0]; ?>" width="200" height="212" />
    <?php }?>

  1. Your video does not appear to be “attached” to the page, hence the 0 as post_parent. And your query arguments do not restrict the results to any particular page.

    You won’t be able to use the normal thumbnail functions. You will have to use something like wp_get_attachment_image to get the thumbnail, if you have a thumbnail at all for the video. I just ran a test and did not have a thumbnail generated for the video.

    If you are not already generating thumbnails, that is your first project. If you are generating them, explain how.
