Capture by gstreamer Khadas Camera at Ubuntu

VIM3

Dear Supporter,

Anybody try to run khadas camera(How To Use MIPI Camera | Khadas Documentation) with gstreamer or any capture app?
This camera doesn’t have v4l2 capture capability.

I known that camera works - becouse guvcview works ok.

I tried find workaround by:

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, width=1920, height=1080, format=BGR !     v4l2sink device=/dev/video14Setting pipeline to PAUSED ...
    Pipeline is live and does not need PREROLL ...
    Setting pipeline to PLAYING ...
    New clock: GstSystemClock
    ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Internal data stream error.
    Additional debug info:
    gstbasesrc.c(3072): gst_base_src_loop (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
    streaming stopped, reason not-negotiated (-4)
    Execution ended after 0:00:00.000844832
    Setting pipeline to PAUSED ...
    Setting pipeline to READY ...
    Setting pipeline to NULL ...
    Freeing pipeline ...

I cant find any solution how deal with “Video Capture Multiplanar”

Hello @Benek

Can you check this pipe? It works on my side that capture a rgb24 video.

$ gst-launch-1.0 v4l2src name=vsrc device=/dev/video0 ! video/x-raw,width=1920,height=1080,framerate=60/1,format=RGB ! filesink location=.//test.rgb

Play the rgb video on PC:

$ ffplay -f rawvideo -pixel_format rgb24 -video_size 1920x1080 test.rgb

Thank a lot!

I can now setup motion with khadas camera:

sudo apt-get install v4l2loopback-dkms
sudo modprobe v4l2loopback video_nr=14
gst-launch-1.0 v4l2src name=vsrc device=/dev/video0 ! video/x-raw,width=1920,height=1080,framerate=60/1,format=RGB !  v4l2sink device=/dev/video14

And set motion to use video14 :slight_smile:
