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 recieves a bayer 10 image from a camera sensor, applies a shifting with value 5 and outputs a bayer 8 image.
