Purpose:
利用C#架構一個RTSP 影像streaming的環境.包含WebCAM控制, FFMpeg使用 and Emgu.CV的應用
Fundamental:
RTSP
即時串流協定（Real Time Streaming Protocol，RTSP）是一種網路應用協定，專為娛樂和通訊系統的使用，以控制串流媒體伺服器。該協定用於建立和控制終端之間的媒體對談。媒體伺服器的客戶端發布VCR命令，例如播放，錄製和暫停，以便於即時控制從伺服器到客戶端（影片點播）或從客戶端到伺服器（語音錄音）的媒體流。FFmpeg
FFmpeg 是一個開放原始碼的自由軟體，它包含了音訊和視訊多種格式的錄影、轉檔、串流功能，同時也是一個音訊與視訊格式轉換函式庫(Library)，許多開源的工具都是基於 FFmpeg 打造的。Reference:
