DirectFB and Gstreamer at same time

DirectFB and Gstreamer at same time
 
|
Hi Guys,
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.
 We are planning to play video on the panels where images are displayed.. Idea is used to gstreamer-imx plugins.
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
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.
Thanks for all your help.

Hi Mohammad, 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. to unblank : echo 0 > /sys/class/graphics/fb1/blank to set resolution : fbset -xres <> -yres <> -fb /dev/fb1 On Thu, Feb 15, 2018 at 11:23 AM, Mohammad, Jamal M <[hidden email]> wrote:

Problem is we are using fb1 for scrolling messages at the bottom.. So, we already have fb0 for directFb. Is there any other solution… From: gstreamer-devel [mailto:[hidden email]]

When I typed the following command, there was nothing displayed on the screen. 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 framebuffer=/dev/fb1"
flags=0x57 The gstreamer logs shows that video played..But not displayed on the screen. I have already executed: echo 0 > /sys/class/graphics/fb1/blank From: gstreamer-devel [mailto:[hidden email]]

A mechanism that allow gstreamer to take control of the FB (preventing the app from rendering text), and when done, give that control back to the app. Short story, design for framebuffer sharing.
