The mobile 3G/4G networks application promotes the development of multimedia technology and some products on mobile terminals. Professional real-time meteorological stream media service is ushering in new opportunities and challenges. Therefore, this work designed a solution of mobile terminal meteorological stream media service. The solution expanded FFMPEG to support encoding and file formats, improved Web services of meteorological streaming media, and provided efficiently diverse meteorological forecasts. In addition, this work also expands a new idea for mobile terminal meteorological applications.
