https://bugs.freedesktop.org/show_bug.cgi?id=68792 --- Comment #5 from Grigori Goronzy --- You have to enable VDPAU output as well. If you don't do that, in case the readback method is used, it won't work because the necessary format conversions have not been implemented yet (I'm working on it). -- You are receiving this mail because: You are the assignee for the bug.
