C # implements FFmpeg video transcoding, playback

recently the company project required to achieve a panoramic camera video interception, but the interception of video demand transcoding upload. After studying the use of FFmpeg transcoding, a detailed introduction to the blog :

The simplest ffmpeg-based transcoding program

The main is the operation process of transcoding, can realize the MP4 converted from the camera to the normal player MP4 format;
