视频嵌入的海报图像

Question

在我的主页上，我有4个嵌入式视频。为了减少加载时间，我想要生成缩略图，链接到另一个页面与真正的嵌入式视频。

如何生成这些缩略图？

注意到：

• 嵌入式视频来自几个视频粉碎网站(每日运动，youtube，vimeo或例如：这段视频 .)
• 视频每天都由网站管理员添加，他无法为每个视频制作缩略图。

如果您需要本地视频的海报/缩略图，可以使用试试这个链接和这也能帮上忙来描述如何在php中使用ff-mpeg获取海报图像、大小、长度、标题。

function captureVideoPosterImg($movie_file = '')
{
    extension_loaded('ffmpeg');
    $movie_file = 'E:\wamp new\www\projects\indiemade_live\developer\uploads\comments\11\14\video\04072011094613_24062011234404_s Sporting Goods- Teams Come Alive.flv';
    // Instantiates the class ffmpeg_movie so we can get the information you want the video  
    $movie = new ffmpeg_movie($movie_file);  
    // Get The duration of the video in seconds  
    echo $Duration = round($movie->getDuration(), 0);  
    // Get the number of frames of the video  
    $TotalFrames = $movie->getFrameCount();  
    // Get the height in pixels Video  
    $height = $movie->getFrameHeight();  
    // Get the width of the video in pixels  
    $width = $movie->getFrameWidth();  
    //Receiving the frame from the video and saving 
    // Need to create a GD image ffmpeg-php to work on it  
    $image = imagecreatetruecolor($width, $height);  
    // Create an instance of the frame with the class ffmpeg_frame  
    $Frame = new ffmpeg_frame($image);  
    // Choose the frame you want to save as jpeg  
    $thumbnailOf = (int) round($movie->getFrameCount() / 2.5);  
    // Receives the frame  
    $frame = $movie->GetFrame($thumbnailOf);  
    // Convert to a GD image  
    $image = $frame->toGDImage();  
    // Save to disk.  
    //echo $movie_file.'.jpg';
    imagejpeg($image, $movie_file.'.jpg', 100);

    return $movie_file.'.jpg';
}
