由于 libLLVM-13.so，AMDGPU VA-API 在 Firefox 上失败

我使用的是 Ubuntu 20.04 LTS x11，内核版本是 5.13.0-39-generic #44~20.04.1-Ubuntu。我安装了 Firefox 并打开了 VA-API，但我注意到错误输出如下

libva info: VA-API version 1.8.0
libva info: Trying to open /opt/amdgpu/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so
libva error: dlopen of /opt/amdgpu/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so failed: libLLVM-13.so: cannot open shared object file: No such file or directory
libva info: va_openDriver() returns -1

每当我尝试播放视频时。

vainfo 似乎有一个很好的输出

我也尝试了 snap 和 flatpak 上的 firefox，但都返回了完全相同的错误。我发现访问 VAAPI 的唯一方法是 flatpak 版本的 vlc，它使用 VA-API 版本 1.12.0。这是问题所在吗？

设置中的版本信息

我从apt.llvm.org对于 Firefox 中的 ubuntu focal 和 vaapi 现在似乎可以使用 MOZ_DISABLE_RDD_SANDBOX=1 环境变量正常工作。

libva info: VA-API version 1.8.0
