Solution 1:

You could open a socket and stream a few seconds from each video, saving the file locally on your Android device.

Once you have it there, so long as it is a recognisable video format, you should be able to create a thumbnail in the usual way (http://developer.android.com/reference/android/provider/MediaStore.Video.Thumbnails.html).

You would need to be careful to make sure that your app actually did not try to play these truncated videos, and went instead to the proper stream URL if someone wanted to view them. You could actually deleted the file after creating the thumbnail if you wanted to be sure.

Doing this may take a little time initially if your camera has a lot of videos, but you should be able to set it up to only create thumbnails for new videos once it has run once which should speed things up.

It is also possible to create thumbnails from streams directly using ffmpeg or VLC (e.g. https://superuser.com/q/592160) but I think you may find the above approach is simpler for your needs and it avoids you having to integrate ffmpeg etc with your app.
