Some update, I tried to play the movie directly with mplayer (I just found how to launch it from the cli ) mplayer -vo vdpau -vc ffh264vdpau theFileToPlay.mkv

But it does when using smplayer or Gnome mplayer. -- dropped frames using vdpau https://bugs.launchpad.net/bugs/661170 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libvdpau in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
