imx6q ipu camera output

shlomiperlman — Sun, 17 Jan 2016 16:22:45 GMT

Hi,

Im using a camera sensor and the driver is configured to RGB565, when using gstremer im getting video from the device

but the images are all blurry in weird colors. this is my command:

gst-launch-1.0 imxv4l2videosrc device=/dev/video0 ! imxeglvivsink

is there a need to give the pipeline a video format parameter?

so far it wont accept "video/x-raw,format=RGB16 width=480 height=640" to any pipeline im giving it.

(also tried YUYV with no success)..

any help appreciated for getting a syntax that works,

thanks!

Hi,

this is my output:

# gst-launch-1.0 imxv4l2videosrc device=/dev/video0 ! 'video/x-raw,format=(string)YUYY,width=640,height=480,framerate=(fraction)30/1' ! imxeglvivsink

gst-launch-1.0 imxv4l2videosrc device=/dev/video0 ! 'video/x-raw,format=(string)UVYV,width=640,height=480,framerate=(fraction)30/1' ! imxeglvivsink

WARNING: erroneous pipeline: could not link imxv4l2videosrc0 to imxeglvivsink0

It also doesn't recognizes "imxv4l2sink" or "imxv4l2src".

my board is from boundary devices.

thanks for helping,

Try gst-inspect to check what devices are actually present in the system. Also, what exactly Boundary Devices board and what BSP by which vendor do you use?

Have a great day,
