摘要

With the popularity of the Internet, User Generated Content increasingly attracts more attention, which proposed the new requirements of the educational video-on-demand, providing the function of video upload for educators and educated. However, there is now a greater variety of video, and the video data which has being digitized is very large. So how to effectively compress video data & audio data, and stores it into the appropriate format to become a serious problem of the Server. FFmpeg and MEncoder, the two kinds of open-source & cross-platform command line program for video compression and processing, has become the most popular core of video compression and processing software. In this paper, the difference between FFmpeg and MEncoder has been tested, based on a combination of both advantages and video coding information. We design the video trans coding module of Server, providing a unified server-side video file format Technology solutions for developers.
