Add a buffer to v4l2src


I am new to GStreamer and am currently working on a project where I want to
include IMU(camera orientation) data to each frame (this will include 4
floats per frame). I am using a e-CAM30_HEXCUTX2 running on a Nvidia TX 2
board. I have recompiled gst_launch.c to gst_myCustomLaunch and am running
this command for local testing: gst_myCustomLaunch v4l2src
device=/dev/video0 !
"video/x-raw,format=(string)UYVY,width=(int)2304,height=(int)1296" !
nvvidconv !
! nvoverlaysink overlay-w=1920 overlay-h=1080 sync=false

I think GstMeta should serve my need but I did not find a way to insert
buffer to the v4l2src. It seems that I could add data to a GstAppSrc but I
am not sure if it is valid to embed/parallel a v4l2src to appsrc and how.

Could someone points me a way to do this? Thanks!
