在linux下的實(shí)時(shí)語(yǔ)音聊天程序，使用了adpcm編碼，同時(shí)還使用了RTP實(shí)時(shí)傳輸協(xié)議，是一個(gè)很好的學(xué)習(xí)實(shí)時(shí)傳輸協(xié)議的程序。- chats the procedure under the linux real-time pronunciation, has used the adpcm code, meanwhile has used the RTP real-time transmission agreement, is a very good study real-time transmission agreement procedure.
