                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_HEIGHTCTRL, 480);
               
                // 设置本地视频编码的帧率

                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_APPLYPARAM, 1);//修改参数

                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_WIDTHCTRL, 640);
...

您好，
1、画面模糊，码率设置的太低了，

1. AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_BITRATECTRL,60000);

复制代码

2、视频卡，帧率可以设置高一些，用640x480分辨率用15fps试下.如果帧率用15fps,关键帧间隔用45

admin

是的，画面模糊通常是分辨率与码率参数设置不匹配，从上面的log来看，分辩率设置为640x480，而码率才60kbps，肯定会模糊了，建议码率设置为400kbps。

您好
码率调高是可以增加画面清晰度
但是画面太卡了，延迟2秒以上

现在用的什么参数呢，把日志发过来看下

wx88933120

您好，补充下摄像头参数
最高只有25fps的帧率
那关键帧间隔还能用45吗？

wx88933120

                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_WIDTHCTRL, 640);
                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_HEIGHTCTRL, 480);
               
                // 设置本地视频编码的帧率
                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_FPSCTRL,15);
                // 设置本地视频编码的关键帧间隔
                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_GOPCTRL,45);
                // 设置本地视频编码的预设参数
                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_PRESETCTRL,3);
                // 设置本地视频编码的码率
                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_BITRATECTRL,300000);
                // 设置本地视频编码的质量因子
                AnyChatCoreSDK.SetSDKOptionInt(AnyChatDefine.BRAC_SO_LOCALVIDEO_QUALITYCTRL,3);

这样画面清晰了，但是太卡了，延迟2秒以上

可能是您的硬件性能不够造成的，建议将分辩率改为：320x240，再看看效果如何？

硬件是全志的芯片A20
摄像头支持500万最高分辨率的
网速也很好的
