You just need to add an extra thumbnailinto the link.
您只需要thumbnail在链接中添加一个额外内容。
Video URL

Using the Dailymotion API
使用 Dailymotion API
https://api.dailymotion.com/video/VIDEO_ID?fields=field1,field2,...
https://api.dailymotion.com/video/VIDEO_ID?fields=field1,field2,...
Replace field1,field2 with
将 field1,field2 替换为
thumbnail_large_url (320px by 240px)
thumbnail_medium_url (160px by 120px)
thumbnail_small_url (80px by 60px)
This API request does not require any Access Tokens.
此 API 请求不需要任何访问令牌。
Example : https://api.dailymotion.com/video/xjfn0s?fields=thumbnail_small_url
示例：https: //api.dailymotion.com/video/xjfn0s?fields=thumbnail_small_url
This HTTP request returns a JSON data with the image link of the video. For processing JSON data check PHP Manual - JSON Decode
此 HTTP 请求返回带有视频图像链接的 JSON 数据。用于处理 JSON 数据检查PHP 手册 - JSON 解码
EDITAs suggested by Ravi using
http://www.dailymotion.com/thumbnail/video/video_idis pretty straight forward. But different resolution images use the API
编辑正如 Ravi 所建议的那样，使用
http://www.dailymotion.com/thumbnail/video/video_id非常简单。但是不同分辨率的图片使用API

$id='xwxadz'; // ID DAILYMOTION EXAMPLE
$thumbnail_medium_url='https://api.dailymotion.com/video/'.$id.'?fields=thumbnail_medium_url';
$json_thumbnail = file_get_contents($thumbnail_medium_url);
$get_thumbnail = json_decode($json_thumbnail, TRUE);
$thumb=$get_thumbnail['thumbnail_medium_url'];
echo $thumb; // Output Example : http://s2.dmcdn.net/BJL4o/160x120-mzR.jpg

Just a simpler way for above objective. Suppose following is the url that I want to download thumbnail
只是实现上述目标的一种更简单的方法。假设以下是我要下载缩略图的网址
http://www.dailymotion.com/video/x17pcar_hadoop-tutorial-how-to-index-and-search-data-with-solr_tech
http://www.dailymotion.com/video/x17pcar_hadoop-tutorial-how-to-index-and-search-data-with-solr_tech
From this url get last string and Extract string id
从这个 url 获取最后一个字符串和提取字符串 id
x17pcar_hadoop-tutorial-how-to-index-and-search-data-with-solr_tech
Now split above string on underscorebasis (_). First one is video id i.e. x17pcar
现在在下划线 (_) 上拆分字符串。第一个是视频 ID，即x17pcar
Now run following url using id to get thumbnail
现在使用 id 运行以下 url 以获取缩略图
