embedded/2024/9/25 13:19:53/

接着在上次编译的基础上增加h265支持
编译支持视频播放的cef控件（h264）

测试页面，直接使用cef_enhancement,里边带着的那个html即可，h265视频去这个网站下载elecard,我修改的这个版本参考了里边的修改方式，不过我的这个版本改完之后，直接video.canPlayType()函数，返回的信息也是提示支持h265播放

CefClient支持播放

测试的edge浏览器不支持播放

需要修改的文件以及内容如下

media/media_options.gni

  enable_platform_hevc =proprietary_codecs && (is_chromecast || enable_hevc_parser_and_hw_decoder)enable_platform_hevc = trueenable_hevc_demuxing = true

media/base/supported_types.cc

    case VideoCodec::kHEVC:// return IsHevcProfileSupported(type);return true;
