Issue with thumbnail creation for videos

[dchilkur]

thumbnails are not created for most of the video assets(most of our
video assets are of type wmv), we see the following messsage logged in
error.log " video is not of a video mime type, asset ignored" while it
is a video with proper extension(.wmv)
