我有一个问题，我只能创建的本地视频文件的缩略图，但不是远程URL，这里是我的code：

I have a problem, I can only create thumbnails of local video files but not of a remote url, here is my code:

bmThumbnail = ThumbnailUtils.extractThumbnail(ThumbnailUtils.createVideoThumbnail("http://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_320x180.mp4", MediaStore.Video.Thumbnails.MINI_KIND), 50, 50);

我希望你能帮助我，

I hope you can help me,

推荐答案

我想有没有简单的方法来建立缩略图，而无需实际下载本地视频。

I suppose there is no easy way to build the thumbnail without actually downloading the video locally.

所以，如果你的问题是我能得到一个缩略图，而无需下载完整的视频？'，我说...没有。

So if your question is 'Can I get a thumbnail without having to download the full video?', I'd say...no.

否则，一旦你已经下载到本地视频的话，我想你可以完美地通过给下载的文件路径中使用 ThumbnailUtils.createVideoThumbnail（...）。

Otherwise, once you have downloaded the video locally, then I guess you can perfectly use ThumbnailUtils.createVideoThumbnail(...) by giving the path to the downloaded file.
