[pkg-nvidia-devel] Bug#592204: nvidia-vdpau-driver: Segfault on VDPAU using apps that call XCloseDisplay

[Andres Mejia]

Package: nvidia-vdpau-driver
Version: 195.36.24-4
Severity: important

Not sure whether this is a problem with NVIDIA's VDPAU driver or with libvdpau,
but I'm fairly certain this is in relation to the driver.

For apps such as xbmc or mplayer that use vdpau for video output, calling
XCloseDisplay results in a segfault. Simple test would be to run

$ mplayer -vo vdpau some_video.mp4

Fortunately, XCloseDisplay is called upon exiting these apps, so there isn't a
major problem with this bug.
