如何修复损坏的 VDPAU?

如何修复损坏的 VDPAU?

症状:

  • 当全屏 VLC ( cvlc) 时,它会报告

    vdpau_display vout 显示错误:输出表面创建失败:VDP_STATUS_INVALID_SIZE

    反复多次,屏幕变黑。

  • 全屏显示时mplayer会报告

    调用 vdp_output_surface_create 时出错:VDP_STATUS_INVALID_SIZE

    并且不能正确全屏显示。

当我试图摆脱屏幕撕裂时,发生了这种情况,并且我无法将其恢复到之前的“工作”(但撕裂)状态。

mpv似乎是唯一仍然可以播放全屏视频的应用程序。

我尝试遵循硬件视频加速指南,因此 libvdpau-va-gl、libva-intel-driver 和 mesa 已安装。我export LIBVA_DRIVER_NAME=i965 VDPAU_DRIVER=va_gl之前尝试过跑步,cvlc但没有成功。我已经重启好多次了

如果我消除libvdpau-va-gl 两个播放器都可以全屏播放视频,相当无撕裂,但至少 VLC 报告

无法打开 VDPAU 后端 libvdpau_va_gl.so:无法打开共享对象文件:没有这样的文件或目录
