Gst-nvjpegenc

The Gst-nvjpegenc plugin encodes images on both dGPU and Jetson platforms. It is the preferred method for encoding JPEG images. On the dGPU platform this plugin is based on the libnvjpeg library, part of the CUDA toolkit. On Jetson it uses a platform-specific hardware accelerator. The plugin accepts I420, RGB input on dGPU platform and I420, NV12 input on Jetson platform and produces JPEG encoded bitstream. On Jetson platform nvjpegenc can also accept SW RAW buffers in I420, YV12, GRAY8 formats. This plugin is not available on (ARM + dGPU) platforms like arm-sbsa. Use nvimageenc plugin instead.
