关于设备选择函数的问题

风逝 · 发表于 2014-3-10 15:27:12

问题：
我按照sdk中的EnumAudioPlayback方法获取了本地的摄像头、音频设备等；
再调用Select选择设备的方法，但是结果不生效！请问需要怎样处理才能让该操作生效了？

您好，请上传相关的log，谢谢。

另外请注意一下Select方法的返回值是多少。

返回值是0，

请问一下，您通过“BRAC_EnumAudioPlayback”可以枚举几个设备出来呢，如果只能枚举出来一个设备，则选择该设备不会有任何效果。

风逝 · 发表于 2014-3-10 15:50:39

枚举了2个设备出来：
1-扬声器 (Realtek High Definition
2-话筒 (Polycom CX100)

admin · 发表于 2014-3-10 15:52:28

您好，您可以用我们标准的Demo程序：SDK包：\bin\demo\BRAnyChatMeeting.exe试一下，看是否可以正常切换？

风逝 · 发表于 2014-3-10 15:53:06

可以加QQ私聊否？
还有反映一个情况，本地视频显示会有2，3秒的延迟，远程倒是感觉正常！这是什么原因造成的了！

admin · 发表于 2014-3-10 15:54:53

本地视频显示会有2，3秒的延迟，远程倒是感觉正常

建议您换一个摄像头，或是换一台计算机做一下对比测试看看，可能与硬件有关。

请问下这个程序有没有c#版本的 anychatmeetingroom 这里面能正确设置！刚才在我的程序里面测试的时候发现，视频设置没得问题可以正常切换，但是放音设备、录音设备每次都不能设置成功！
设置了值后返回0，马上调用又是原来默认的值去了！
还有就是和标准的程序比：我枚举出来的这个播放设备，感觉没有显示完全： 1-扬声器 (Realtek High Definition

admin · 发表于 2014-3-10 16:14:28

您调用选择API之后的返回值为0吗？
