Gst-nvimagedec#

The Gst-nvimagedec plugin decodes images on dGPU and (ARM + dGPU) platforms like arm-sbsa. This plugin is based on the libnvjpeg library which part of the CUDA toolkit. The plugin accepts a JPEG encoded bitstream and produces RGB output. jpegparse plugin should be used to parse the encoded frame before nvimagedec, since it does not have an internal bitstream parser.
