Unable to play video in fb1 framebuffer using gstreamer plugin in L4.9.11 release

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

why do you need to use v4l2sink first then use fbdevsink? how about use

gst-launch-1.0 filesrc location=/media_files/test_play.mp4 ! decodebin ! imxv4l2sink device=/dev/fb1

HI Joan,

I'm using customized camera application for local streaming, it can only able to stream camera in video17(fb1 framebuffer) node.

In that case if I run the imxv4l2videsink Gstreamer plugins then I can't able to run the camera application.

And I also have some issue while streaming 3.5MP(2304x1536) resolution in imxv4l2sink plugins.

Best Regards,

Bala
