HI,
we are developing the application that get video from a camera and hardcode the image directly. We using the Xavier Nx for our Application.Can gstreamer hardcode the image data collected by our camera, the image data is obtained through the sdk of a special camera, and the format is 8-bit grayscale image

We have

  • JETPACK 4.4 [L4T 32.4.3]
  • CUDA: 10.2.89
  • OpenCV: 3.4.13 compiled CUDA: YES
  • GStreamer 1.14.5

Hi,
A possible solution is to use appsrc plugin to run like:

appsrc ! video/x-raw,format=GRAY8,width=_WIDTH_,height=_HEIGHT_ ! nvvidconv ! video/x-raw(memory:NVMM) ! ...

And implement capturing frame data in appsrc plugin.

the camera image data has been saved in opencv mat and the format is gray8.
How can i use GStreamer hardcode it and send it out by RTP/UDP? I need to use opencv: (videoCapture and videoWriter) to achieve it.how can I write pipeline in detail used for videoCapture?
