=====================================================

本文記錄基於libVLC的最簡單的推流器。該推流器可以將本地的視訊檔案轉碼後推送至目標流媒體伺服器（也可以是一個組播地址）。

最簡單的基於libVLC的推流器

該推流器的程式碼十分簡單，只用到了幾個函式：

libvlc_new()：建立libvlc_instance_t。
libvlc_vlm_add_broadcast()：增加一個廣播（broadcast）。
libvlc_vlm_play_media()：播放指定名稱的廣播（broadcast）。
libvlc_vlm_stop_media()：停止指定名稱的廣播（broadcast）。
libvlc_vlm_release()：釋放ibvlc_instance_t。

• 輸入視訊轉碼為H.264
• 音訊轉碼為mp2
• 封裝格式設定為MPEG-TS
• 以UDP的形式傳送至組播地址“udp://233.233.233.233:6666”
