·问题原因
用UE4的WebBrowser浏览检测网站,可以发现如图Video部分的H.264是不支持的,原因是UE4的WebBrowser自带的cef3为3071版本,默认不支持H.264等直播流,导致web里的直播流无法播放。
测试浏览器对H5标准支持网站:HTML5test - How well does your browser support HTML5?

·解决方案
重新编译cef3源码,改成支持H.264,然后在UE4安装目录下替换相关文件。
网友编译好的cef3下载地址:

替换路径如下:
\Epic Games\UE_4.26\Engine\Binaries\ThirdParty\CEF3\Win64,替换所有文件
\UE_4.26\Engine\Source\ThirdParty\CEF3\cef_binary_3.3071.1611.g4a19305_windows64\Release,只替换libcef.lib
解决后的如下图可见,Video部分支持H.264。

·UE4里如何查web的console?
点击web里的任意元素,按键盘 Shift + Ctrl + I即可弹出console窗口
