Alternately, in the case of ``ROCJPEG_OUTPUT_YUV_PLANAR``, the data is written to the corresponding channels of the ``RocJpegImage`` destination structure.
The destination buffers should be large enough to be able to store output of specified format. These buffers should be

Using the rocJPEG API, you can decode compressed JPEG streams while keeping the resulting YUV
