Is it possible to get the thumbnail image from a video Url? I need to 开发者_StackOverflow中文版thumbnails of videos in a list view.
Yes its possible to get the thumbnail of a video using ThumbnailUtils.
FileOutputStream out;
File land=new File(Environment.getExternalStorageDirectory().getAbsoluteFile()
+"/portland.jpg");// image file use to create image u can give any path.
Bitmap bitmap=ThumbnailUtils.createVideoThumbnail(filePath, MediaStore.Video.Thumbnails.FULL_SCREEN_KIND);//filePath is your video file path.
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] byteArray = stream.toByteArray();
out=new FileOutputStream(land.getPath());
out.write(byteArray);
out.close();
If you are specifically asking about youtube videos then there are automatically 4 generated images by Youtube.

It is working in my case
Uri videoUri = data.getData();
String selectedPathVideo="";
selectedPathVideo = ImageFilePath.getPath(getApplicationContext(), videoUri);
Log.i("Image File Path", ""+selectedPathVideo);
try {
Bitmap thumb = ThumbnailUtils.createVideoThumbnail(selectedPathVideo, MediaStore.Video.Thumbnails.MICRO_KIND);
imgFarmerVideo.setImageBitmap(thumb);
} catch (Exception e) {
e.printStackTrace();
}

Try ThumbnailUtils, to get video bitmap from file path
ThumbnailUtils.createVideoThumbnail(filePath,MediaStore.Video.Thumbnails.MINI_KIND);
It is possible to get thumbnail image of video from video url.
If your video type is Vimeo follow below steps:
1)Suppose your Video Url is: http://player.vimeo.com/video/17314292
2)Get Video Id From Url : eg. 17314292
3)Call WS with Video id and XMl format http://vimeo.com/api/v2/video/17314292.xml
You will get "thumbnail_small","thumbnail_medium","thumbnail_large" in xml format for video thumb from video id
If your video type is YouTube follow below steps:
1)Video Url : http://www.youtube.com/embed/Nl2iMF0yKW8
2)Get Video Id From Url : eg. Nl2iMF0yKW8
3)Replace video id in this url http://i3.ytimg.com/vi/Nl2iMF0yKW8/default.jpg
NOTE:Just replace your id here.
It's very important to identify the components of a problem. I'd actually say you have two separate problems:
Downloading a file from an URL.
Creating a thumbnail image from an incomplete video file.
Look into those two separately, you'll find plenty of information.
To get thumbnail from the URL, i only got one solution till now, You have to use This library
It Supports file, http, https, mms, mmsh and rtmp protocols
and
It Supports aac, acc+, avi, flac, mp2, mp3, mp4, ogg, 3gp and more! formats (audio and video):
It is possible to get a thumbnail from a video file or url using FFMPEG.
FFMPEG must be built using the NDK (or you can find some Android built FFMPEG binaries). Here is a GitHub project to build FFMPEG:
https://github.com/guardianproject/android-ffmpeg
You can then include the FFMPEG binaries with your app and execute FFMPEG from code in your app to generate an image from the video (local or URL) using a command like:
ffmpeg -i videosite.com/video.flv -ss 00:00:15.000 -vframes 1 thumbnail_out.png
One thing to consider is at what seek time (option -ss) you grab the thumbnail for it to be a meaningful image that represents the video.
