远程视频质量

[liuming1989]

使用过程中，远程视频的质量被压缩了，预览画面很清晰，但是对方看到的画面就像是被压缩了，查看依赖库，更改视频尺寸和fps没什么效果，请问有什么方式提高视频的质量嘛？目前看到所有的qq群都已经满了，能多开一个嘛

有个设置最大码率的参数

[liuming1989]

哦，能告诉我一下吗？我知道rtc-chat这里面有地方能设置视频的 分辨率 默认我看是 640X480，还有一个fps ,是这个地方吗？

请问一下是什么参数设置视频质量呀？实在是没找到

所以，你找到设置视频质量的方法了么？ 能否分享下

大佬您好，我是用的是"branch_nodejs"分支代码，请问您这些配置是加在PeerConnectionHelper类里面吗？

感谢大佬，比之前清晰了。能否加您个联系方式呢，我Q2920501612

在最新版中，找不到这个PeerConnectionHelper了，然后复制setStartBitrate方法放到RTCPeer中，好多报错；要怎样解决？大佬

大佬，新版本怎么调高远程视频质量呀？
