--- Comment #2 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
77        g_return_val_if_fail (info->width <= meta->width, FALSE);
(gdb) print info->width
$1 = 896
(gdb) print meta->width
$2 = 512


And the resolution changed from 512 to 896. direct-rendering=false on
avdec_h264 makes it work.


I suspect something wrong with the buffer pool code in this commit:

    aviddec: Re-enable direct rendering

    This is achieved by using a tempory internal pool. We can then switch to a
    downstream pool if the downstream pool buffer have matching strides.
