Question

我正在尝试使用FreeSWITCH和pjsip库进行视频通话。音频通话正常进行。为了启用视频，我进行了以下更改：

1. I followed all the steps mentioned here.
PJSIP video user guide (https://trac.pjsip.org/repos/wiki/Video_Users_Guide)


2. FreeSWITCH                
a. Updated /usr/local/freeswitch/conf/vars.xml with h264 codec.
   <XPREPROCESScmd="set"data="global_codec_prefs=H264,OPUS,G722,PCMU,PCMA"/>

b. However, h264 is not showing in the codecs list (show codecs)            

c. when I make a video, call... FreeSWITCH is converting it to an audio call. When I initiate a call Video port was opened but later it was closed.

从pjsip到FreeSwitch（第一段）是视频通话...但是第二段是audo通话。

v = 0

o = FreeSWITCH 1540768194 1540768195输入IP4 192.168.100.41

s = FreeSWITCH

c = IN IP4 192.168.100.41

t = 0 0

m =音频26506 RTP / AVP 0 96

a = rtpmap：0 PCMU / 8000

a = rtpmap：96电话事件/ 8000

a = fmtp：96 0-16

a = ptime：20

a = rtcp：26507 IP 4 192.168.100.41

m =视频0 RTP / AVP 19

请让我知道如何继续进行操作。

Answer 1

请检查以下fs_cli中的命令是否返回true或false。

module_exists mod_h26x

如果返回true，则加载h264编解码器，否则未加载。用于加载模块执行以下命令

load mod_h26x

如果在加载模块时发现任何错误，则需要从freeswitch源代码编译mod_h26x，该模块将出现在mod / codec目录中。只需在模块源代码目录中进行make和make install，然后通过上述命令加载模块即可。

FreeWITCH：显示编解码器不显示H264编解码器吗？
