avidemux3_qt4: xcb_io.c:445: _XReply: Assertion `!dpy->xcb->reply_data' failed.

[karl]

If I just start avidemux 2.6, then close it without ever having opened a video, avidemux crashes at the following position:

Code Select Expand


[cleanup]  Destroying vdp device..
avidemux3_qt4: xcb_io.c:445: _XReply: Assertion `!dpy->xcb->reply_data' failed.

When I do load a video before closing (even without playing/editing it), avidemux does not crash, so I assume some kind of vdpau initialization is not performed when no file is ever loaded, but it assumed to have been done when admVdpau::cleanup() is called.

[mean]

It appeared recently with no change on avidemux side
Maybe a nvidia / x11 incompatibility

[mean]

maybe fixed

[karl]

Yes, this issue is fixed.

(Display using vdpau works fine, decoding the H.264 video using vdpau does not work, though. But I can live with software decoding for now.  )
