关于 ubuntu 下浏览器的硬件加速问题

发一下
dpkg -l | grep xserver-xorg-video-
dpkg -l | grep libva
dpkg -l | grep vdpau
glxinfo | grep OpenGL
vainfo
vdpauinfo

“吃大量 CPU ” 是吃多少 CPU ？

安装一个 radeontop，然后看看放视频的时候 GPU 的使用率。

另外还有

抱歉，经过我的搜索后我发现 chrome 和 firefox 都不支持在 Linux 上加速视频解码。但是可以对渲染进行硬件加速。

chromium 存在一个非官方的补丁以启用视频解码加速，如果有需要可以自行编译打过补丁的 chromium。

所以，不用担心，[[chrome，chromium 和 firefox 都会使用 GPU 来加速渲染，不会影响你的网页浏览体验，只有播放视频的解码部分才会不使用硬件加速。]] 但是你用浏览器看视频的时间应该不会很多吧？如果需要看网络上的视频时，运行 mpv 或者 vlc 打开网络串流即可，它们有很好的视频解码硬件加速支持。

@iwtbauh radeontop 结果：
首先 CPU 是双核。
本地用 mplayer 播放 h.264 视频，1.2kbps 1080P@23.976fps，CPU 占 20%，Graphic Pipe 占用 30%。
本地用 mplayer 播放 h.264 视频，4.2kbps 1080P@23.976fps，CPU 占 60%，Graphic Pipe 占用 30%。
B 站视频，6.0kbps 1080P@30fps，CPU 占 100%，Graphic Pipe 大于等于 55%。
