<div dir="ltr">Hi Mohammad,<div> from the gstreamer pipeline you are using IMX6 processor. One solution would be to use the overlay frame buffer /dev/fb1 of IMX6 for the text part and /dev/fb0 for the video part. you can modify the imxipuvideosink framebuffer=/dev/fb1 and check. Please unblank and set the size of the overlay frame-buffer before you run the command. Also adjust the alpha value for transparency.</div><div>to unblank : echo 0 > /sys/class/graphics/fb1/blank</div><div>to set resolution : fbset -xres <> -yres <> -fb /dev/fb1</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Feb 15, 2018 at 11:23 AM, Mohammad, Jamal M <span dir="ltr"><<a href="mailto:MohammadJamal.Mohiuddin@ncr.com" target="_blank">MohammadJamal.Mohiuddin@ncr.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>Hi Guys,</div>
<div> </div>
<div>We had an application using DirectFB which divides the screen into four panels. Attached Image. Big panel (Left side ) is updated every second with text, the other three panels ( Right Side ) has static images.</div>
<div> </div>
<div><img src="cid:FB4C5E87847E504AB93A71EDD65727D0@namprd15.prod.outlook.com"> </div>
<div>We are planning to play video on the panels where images are displayed.. Idea is used to gstreamer-imx plugins.</div>
<div> </div>
<div>gst-launch-1.0 playbin uri=file:///Images/hash.mp4 video-sink="imxipuvideosink window-height=240 window-width=360 window-y-coord=0 window-x-coord=684" flags=0x57</div>
<div> </div>
<div>When we play the video using the above command, we are facing problem : the text panel in the big panel will be updated every second which is flickering the video. I believe this is due to fact that DirectFB is updating framebuffer while trying to write
text. Is there any way to avoid this flickering and allow both DirectFB and gstreamer to work in parallel.</div>
<div> </div>
<div>Thanks for all your help.</div>
