Gstreamer not playing videos in weston/wayland

Thu Sep 29 03:46:25 UTC 2016

Abin,

Do you get the issue with this pipeline ?

gst-launch-1.0 filesrc location=sample.bgra !  video/raw, format=BGRx,
 width=352, height=288, framerate=25/1 !  waylandsink ?

Which is your wayland version and the rendering mechanism (pixman, EGL) ?

,
Sudip
