WebRTC MCU( Multipoint Conferencing Unit)服務器調研

接觸過的有licode、kurento.

licode的缺陷：文檔支持有限，licode的app client庫只有js的

kurento的優點：文檔齊全，Demo俱備，封裝API比較齊全。它的主要特性：

 

• Networked streaming protocols, including HTTP, RTP and WebRTC.
• Group communications (MCUs( Multipoint Conferencing Unit) and SFUs(Selective Forwarding Unit.) functionality) supporting both media mixing and media routing/dispatching.
• Generic support for computational vision and augmented reality filters.
• Media storage supporting writing operations for WebM and MP4 and playing in all formats supported by GStreamer.
• Automatic media transcodification between any of the codecs supported by GStreamer including VP8, H.264, H.263, AMR, OPUS, Speex, G.711, etc.

除了以上特性，kurento對於咱們要作的WebRTC MCU服務，有專用的Room API，方便實現此類功能。其豐富的視頻處理功能也是選用這個解決方案的重要緣由之一。也能夠基於kurento作Peer2Peer的信令服務。
