您好，第二份日志显示该用户还没有进入房间，另外通话图像质量低是指哪方面？

kinghong · 发表于 2015-8-4 10:03:28

是画面清晰度不够，用的是高清摄像机

admin · 发表于 2015-8-4 10:07:08

Apply video parameter:1920x1080, bitrate:1500000, quality:3, gop:30, fps:30, preset:3, codec:0

您好，建议使用质量模式（建议在网络带宽有保障的条件下使用该模式），即bitrate=0，画面清晰度将会显著提升，参考：如何设置AnyChat视频质量？

另外在码率模式下，您还可以提高quality、preset的值来提高视频的清晰度。默认两者均为默认值“3”，属于中等质量。

kinghong · 发表于 2015-8-4 15:41:17

请问在码率模式下参数如何设置可提高视频画面质量

在带宽有保证的情况下，正确输入相对应的分辨率、码率和帧率，可提高音视频质量。

请问quality和preset这两个值要设置成多少可以提高画面质量？

admin · 发表于 2015-8-5 09:44:11

您试试都设置为5，看是否有改善。

详细信息可参考：如何设置AnyChat视频质量？

另外从日志看您所使用的SDK版本较旧（Load BRAnyChatCore.dll success!(V5.2 Build Time:Feb 10 2015 14:09:19)），建议您升级到最新版本，点击打开下载页面。

设置为5与设置为3相比带宽要求有变化吗
