哪几个网站做acm题目,游戏网站怎么做seo,jsp网站开发过程,十大医疗器械公司排名查了下rtp.c的源码#xff0c;远端端口为0就意味着recvonly#xff0c;但其实不然#xff0c;调用switch_rtp_new会马上返回失败
经过反复测试#xff0c;增加下面几行代码之后终于变成了recvonly: tech_pvt-mode RTP_RECVONLY; rtp_flags[SWITCH_RTP_FLAG_AUTOADJ];…查了下rtp.c的源码远端端口为0就意味着recvonly但其实不然调用switch_rtp_new会马上返回失败
经过反复测试增加下面几行代码之后终于变成了recvonly: tech_pvt-mode RTP_RECVONLY; rtp_flags[SWITCH_RTP_FLAG_AUTOADJ]; switch_channel_set_variable(channel, rtp_auto_adjust_threshold, 1); 有什么用
用处大了可以做录音呀监听呀什么的接收别人的rtp流下面是一个lua例子 function debug(s) freeswitch.consoleLog(ERR, s or ) end local api freeswitch.API() local uuid api:executeString(create_uuid) debug(uuid .. uuid .. \n) local local_addr api:executeString(global_getvar local_ip_v4) local local_port 2000 local remote_addr local_addr -- 必须给远端地址和远端端口赋值尽管实际不发送rtp流 local remote_port 3000 -- local ptime 20 local codec PCMA local pt 8 local rate 8000 local cmd bgapi originate cmd cmd .. [origination_uuid .. uuid .. ] cmd cmd .. string.format([local_addr%s,local_port%d,remote_addr%s,remote_port%d,ptime%d,codec%s,pt%d,rate%d], local_addr, local_port, remote_addr, remote_port, ptime, codec, pt, rate) cmd cmd .. rtp cmd cmd .. lua(asr.lua) debug(cmd) local reply api:executeString(cmd) debug(reply .. reply) stream:write(reply) 呼叫成功后就执行lua asr.lua至于asr.lua要怎么写得您自己脑补了
