我们的项目中有很多尺寸（宽度和高度）不同的视频。

尝试以下解决方案

解决方案1 ：裁剪或调整高度

 Expression<Func<TUser, bool>> filter = t => string.IsNullOrWhiteSpace(tenantId) ? t.TenantId != null : t.TenantId == tenantId;

Image with less black border Image with more black border

解决方案2 ：将其用作背景图像，将其居中并更改高度。

         HTML
          <div class="thumb">
            <img src="...">
          </div>
         
         CSS
          
        .thumb {
           overflow: hidden;
         }
        .thumb img {
          margin: -10% 0;
          width: 100%;
         }            

Failing for some sceanrios , because of image black border size is varying for few images.

Screenshot for reference

解决方案3：获取不带有黑色边框的Youtube图像（使用mqdefault.jpg而不是0.jpg）

关注此链接How do I get a YouTube video thumbnail from the YouTube API?

基于以上链接，我们知道mqdefault.jpg图像没有黑色边框

    .youtubePreview {
        background:url('http://img.youtube.com/vi/aOPGepdbfpo/0.jpg') center no-repeat;
        height:204px;
        width:480px;
    }
    
    or
    
     also tried with background-image
     
     <div class="bgimg" style="background-image: url(&quot;https://img.youtube.com/vi/8yxZ-k0xI9s/0.jpg&quot;); height:275px "></div>
    
 Example: 450*275 failing       
     
We have video with different sizes so it works for some width and its failing for other widths.

mqdefault image

许多大小（高度和宽度）不同的视频
预览图像黑色边框长度也有所不同

任何人都可以提出一些想法来实现这一目标吗？

预先感谢

Answer 1

以下是我改编的一些示例（通过检查嵌入视频并查看其CSS样式）：

示例1：

.ytp-cued-thumbnail-overlay-image {
  background-size: cover;
  -moz-background-size: cover;
  -webkit-background-size: cover;
  background-position: center;
  background-repeat: no-repeat;
  width: 100%;
  height: 100%;
  position: absolute;
}

<p>Image 1: </p>
<div class="ytp-cued-thumbnail-overlay-image" style="background-image: url('https://i.ytimg.com/vi/3TJgmUGFHqw/sddefault.jpg');"></div>

示例2：

.ytp-cued-thumbnail-overlay-image {
  background-size: cover;
  -moz-background-size: cover;
  -webkit-background-size: cover;
  background-position: center;
  background-repeat: no-repeat;
  width: 100%;
  height: 100%;
  position: absolute;
}

<p>Image 2: </p>
<div class="ytp-cued-thumbnail-overlay-image" style="background-image: url('https://i.ytimg.com/vi/NNgYId7b4j0/maxresdefault.jpg');"></div>
