JPEG decode sample

The jpeg decode sample illustrates decoding a JPEG images using rocJPEG library to get the individual decoded images in one of the supported output format (i.e., native, yuv, y, rgb, rgb_planar). This sample can be configured with a device ID and optionally able to dump the output to a file.

Prerequisites:

Build

mkdir jpeg_decode_sample && cd jpeg_decode_sample
cmake ../
make -j

Run

./jpegdecode -i     <[input path] - input path to a single JPEG image or a directory containing JPEG images - [required]>
             -be    <[backend] - select rocJPEG backend (0 for hardware-accelerated JPEG decoding using VCN,
                                                         1 for hybrid JPEG decoding using CPU and GPU HIP kernels (currently not supported)) [optional - default: 0]>
             -fmt   <[output format] - select rocJPEG output format for decoding, one of the [native, yuv, y, rgb, rgb_planar] [optional - default: native]>
             -o     <[output path] - path to an output file or a path to a directory - write decoded images to a file or directory based on selected output format [optional]>
             -d     <[device id] - specify the GPU device id for the desired device (use 0 for the first device, 1 for the second device, and so on); [optional - default: 0]>
