Thanks sudip
I tried with
Gst-launch1-0 videotestsrc ! Video/x-raw, format =BGRA,
width=352,height=288,framerate=25/1 ! Waylandsink
I get currect the output.
But when tried to play using
Gst-launch-1.0 filesrc location=sample.bgra ! Video/x-raw, format =BGRX,
width=352,height =288,framerate =25/1 ! videoconvert ! Waylandsink.
I get a black window that i am attaching with this mail. I am already
specified my gstreamer version and weston version. I dont know why video
not showing on this window.
Regards
Abin
