General

CUDA ISP provides three different GStreamer elements to apply the different algorithms to raw image data coming from a camera sensor. The 3 elements are:

  • cudashift
  • cudadebayer
  • awb

In the following sections you can see examples on how to use this elements.

cudashift

  • Input:
    • Bayer 10/12/14/16
  • Output
    • Bayer 8
  • Property
    • shift: number of bits to shift right per pixel.
GST_DEBUG=WARNING,*shift*:LOG gst-launch-1.0 -ve v4l2src io-mode=userptr ! 'video/x-bayer, bpp=10, format=rggb' ! cudashift shift=5 ! 'video/x-bayer, bpp=8, format=rggb' ! cudadebayer ! 'video/x-raw, format=RGBA' ! fakesink

The following pipeline receives a bayer 10 image with 4k resolution from a camera sensor, applies a shifting with a value of 5 and outputs a bayer 8 image.

gst-launch-1.0 -ve v4l2src io-mode=userptr ! 'video/x-bayer, bpp=10, format=rggb' ! cudashift shift=5 ! fakesink

cudadebayer

  • Input
    • Bayer 10/12/14/16
  • Output
    • RGB or I420
  • Property
    • shift: number of bits to shift right per pixel.
