Bug ID: 744839
Summary: gl: Flickering when libav direct rendering doing
Version: git master
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: nicolas.dufresne at collabora.co.uk

GNOME version: ---
When playing inside playbin, we often get flickering when libav direct
rendering. This often starts when seeking, and is always visible on OSX.
gst-launch-1.0 playbin uri=... video-sink="glimagesink"
One thing to notice is that forcing 1 more buffer in the pipeline fixes the
gst-launch-1.0 playbin uri=... video-sink="queue min-threshold-buffer=1 !
This is a regression from previous version where direct rendering
(VideoAlignement) was not supported. Even though, not doing direct rendering is
equivalent to this extra buffer case.
