This type of bug needs to be created on the specific media service, and we need to stop using moblin-media to host all bugs for media related things.

Current the gstreamer depends on seeking operation to get a video frame for thumbnail. These asfs are abnormal. They have no correct index information,so can't seek. So can't get the thumbnail by seek. I tried to play a video to get a none black frame. This method occupies CPU and For some videos, the time is too long, will cause dbus exception.

This is too low a priority to de-focus our efforts on show stopper bugs. Marking as 'fix-later'
