在 Ubuntu 16.04.3 Server 上,当我尝试在基于 Qt Quick 的图形应用程序(eglfs
后端(EGL 全屏))中启动视频时,视频开始抽搐(变得断断续续、生涩,不知道该如何形容)。在之前的安装中,视频播放流畅。我*.so
对新旧安装的视频播放过程中加载的树进行了比较。没有区别。我猜想问题可能出在硬件加速上。
安装gstreamer1.0-vaapi
数据包并重新启动应用程序后,如果我按“播放”按钮,它就会挂起。日志包含以下消息:

然后我输入:

mesa-va-drivers: /usr/lib/x86_64-linux-gnu/dri/gallium_drv_video.so
# apt install mesa-va-drivers
# ls /usr/lib/x86_64-linux-gnu/dri/gallium_drv_video.so
ls: cannot access '/usr/lib/x86_64-linux-gnu/dri/gallium_drv_video.so': No such file or directory
这怎么可能?有证据表明,该软件包mesa-va-drivers
应该包含该*.so
文件。其他软件包都没有。我应该自己构建 mesa va 驱动程序吗?

答案1
我实际上也遇到了同样的问题。是的,@RobertRiedl 评论说哪里是gallium_drv_video.so
正确的。但是,它没有被列出,因为它只是指向另一个文件的链接。
为了修复它我做了以下事情:
cd /usr/lib/x86_64-linux-gnu/dri/
sudo rm gallium_drv_video.so
sudo apt install mesa_va_drivers
sudo ln -s radeonsi_drv_video.so gallium_drv_video.so
运行上述操作后,检查 vainfo 是否运行正常:
要纠正无法连接到 X 服务器,请运行:
export DISPLAY=:0
xhost +
运行vainfo
以确保其正常工作:
:~$ vainfo

libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/r600_drv_video.so
