cms01> callbridge restart
4. 从CMS SSH命令行和CMS日志验证Callbridge状态以确认AV1 Video Codec is enabled。
以下是CMS SSH命令行状态的示例:
cms01> callbridge Listening interfaces : a Preferred interface : none Key file : cms.key Certificate file : cms.cer Address : none CA Bundle file : root.cer C2W trusted certs : cms.cer Callbridge cluster trusted certs : cms.cer Callbridge trust branding certs : none UCM trusted certs : cucmtomcat.cer UCM verification mode : enabled IMPS trusted certs : impcup.cer IMPS verification mode : enabled WC3 JWT Expiry in hours : 24
AV1 Video Codec : enabled
以下是在CMS日志上启用AV1编解码器状态的示例:
2024-03-06T09:35:42.003 user.info cms01 host:server: INFO :
AV1 Video Codec Enabled for Content: 1
注意:必须在CMS集群中的所有Callbridge服务器上启用AV1编解码器。
验证
1. 内容演示者的媒体运行状况统计数据显示,在Chrome浏览器上,内容协商编解码器为AV1。
演示者内容编解码器为Chrome上的AV1
2. 内容接收器的媒体运行状况统计信息显示,从CMS服务器接收内容时,Chrome浏览器上的内容协商编解码器为AV1。
接收方内容编解码器为Chrome上的AV1
3. 如果CMS上启用了AV1,但浏览器不支持AV1,则CMS和浏览器之间的内容传输将选取浏览器支持的编解码器。
此示例显示CMS和Firefox浏览器内容协商编解码器为H.264。
接收方内容编解码器是Firefox上的H.264
故障排除
1. 从CMS日志中可以看到主讲者开始共享内容:
2024-03-06 12:36:05.737 Info call 49: new video presentation request from user "guest3577572234" 2024-03-06 12:36:05.737 Info call 49: becoming floor
2. 通过Chrome浏览器上的演示者webrtc日志,您可以看到CMS支持会话描述协议(SDP)消息中的AV1编解码器,并且内容共享编解码器为AV1。
您可以通过Chrome浏览器的chrome://webrtc-internals/收集webrtc日志。
这是webrtc日志中CMS SDP消息的示例。

注意:思科不保证试用版功能将来会过渡到完全受支持的功能。试用版功能可能会根据反馈而改变,将来可能会更改或删除这些功能。
注意:
- SIP终端不支持此功能。
- AV1传输仅在Chrome浏览器上经过测试和认证。
- 如果在会议服务器中启用了AV1,但浏览器不支持它,则内容传输将采用浏览器支持的编解码器。
- 启用主板管理处理器(MMP)命令后,重新启动Callbridge以确保更改已应用。
