<p class="MsoNormal">Hi Mohammad,<o:p></o:p></p>
<div>
<p class="MsoNormal"> 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.<o:p></o:p></p>

<p class="MsoNormal">to unblank : echo 0 > /sys/class/graphics/fb1/blank<o:p></o:p></p>

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.<o:p></o:p></span></p>
