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.
