Call this method after setDataSource(). This method finds a representative frame at any time position if possible, and returns it as a bitmap. This is useful for generating a thumbnail for an input data source. Call this method if one does not care about where the frame is located; otherwise, please call MediaMetadataRetriever.GetFrameAtTime(long) or MediaMetadataRetriever.GetFrameAtTime(long, Android.Media.Option)
