Hi all,

I am working on a project which is based on i.MX6Q board . It has a camera module which is on MIPI CSI2 interface .

When i stream a video using gstreamer command the last frame is freezing when i use CTRL+C to terminate the streaming.

when i use mfw_vl4sink with device=/dev/video17 it's working fine but when i change it to video16 or video18 or video19 it freezes.


gst-launch mfw_v4lsrc device=/dev/video1 capture-mode=4  ! mfw_v4lsink device=/dev/video17


And also we want to display a video on LCD and HDMI both using a single source using gstreamer command.In that case also it not clearing the last frame of buffer.

Some where in source code of vl4_sink it's given to clear it using system("cat /dev/zero > /dev/fb2\n"); but still not able to get it done.


Command for multi display(LCD+HDMI)

gst-launch mfw_v4lsrc device=/dev/video1 capture-mode=4 ! tee name=splitter ! queue ! mfw_v4lsink device=/dev/video17 splitter. ! queue ! mfw_v4lsink device=/dev/video18
