What I see (happens to be in English) is: "Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory"
This is on Firefox 11.10, Kubuntu 11.10, with an ATI Radeon card (not an NVidia). Flash works fine within the browser. Strace'ing and grep'ing around in binaries, not in source,, I'd guess (could be wrong) that the error comes from /usr/lib/libvdpau.so.1 trying to find "%slibvdpau_%s.so%s", where the second "%s" is "nvidia", where I have no such libvdpau_nvidia.so file. One possible interacting detail -- my $HOME/.macromedia/Flash_Player/macromedia.com/support/flashplayer/sys/settings.sol file, in fact the entire $HOME/.macromedia/Flash_Player sub-directory tree, has been repeatedly removed and rebuilt in whatever way it is automatically rebuilt when Firefox is restarted and that sub-directory tree is missing. I do this removal automatically on a routine basis, as part of my effort to improve macromedia flash security. I notice from the strace that the above settings.sol file is referenced just before the failed efforts to find an instance of libvdpau_nvidia.so are attempted. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/808254 Title: Failed to open VDPAU backend libvdpau_nvidia.so Status in “firefox” package in Ubuntu: Confirmed Bug description: If I open firefox from a terminal ( $ firefox & ) after some hours I see dozens of errors like this: Failed to open VDPAU backend libvdpau_nvidia.so: no se puede abrir el fichero del objeto compartido: No existe el fichero o el directorio Failed to open VDPAU backend libvdpau_nvidia.so: no se puede abrir el fichero del objeto compartido: No existe el fichero o el directorio In my case, the Flash videos are executed properly, with sound.
