Hi,

 

I am using the yocto Morty release and Linux 4.9 kernel, in that I am trying to play video in fb1 framebuffer using Gstreamer plugin.

 

I can able to play the video in fb1 framebuffer before using "imxv4l2sink", but after using the "imxv4l2sink" gstreamer plugins I can't able to play video in fb1 framebuffers by using "fbdevsink".

 

 

  • Playing video by using imxv4l2sink:
    gst-launch-1.0 filesrc location=/media_files/test_play.mp4 ! decodebin !  imxv4l2sink

  • Playing video in fb1 by using fbdevsink:
    echo 0 > /sys/class/graphics/fb1/blank
    fbset -fb /dev/fb1 -xres 1920 -yres 1080  
    gst-launch-1.0 filesrc location=/media_files/test_play.mp4 ! decodebin ! videoconvert ! fbdevsink device=/dev/fb1

 

Why this Gstreamer behaviour is irregular?

 

Hoping for better guidance .

 

 

Best regards,

Bala
