The JPEG processing block is responsible for JPEG compression, decompression, image scaling, decoding (YUV420, YUV422H/V, YUV444, YUV400), and color space conversion (RGB to YUV).

Features

  • JPEG codec (8/12 bits per channel)
  • JPEG2000 codec (8-16 bits per channel)

Input (encode) format:

  • Subsample format: YUV420
  • Resolution (up to): 16K x 16K
  • Pixel pack format
    • Semi-planar/Planar for 420

Output (decode) formats:

  • Resolution (up to): 16K x 16K
  • Pixel pack format
    • Semi-planar/Planar for YUV420
    • YUY2/Planar for 422H/422V
    • Planar for YUV444/YUV

nvjpegenc JPEG encoder element
nvjpegdec JPEG decoder element

Multimedia API

The Multimedia API provides the NvJpegEncoder and the NvJpegDecoder helper classes. The examples located in ~/tegra_multimedia_api/samples/05_jpeg_encode and ~/tegra_multimedia_api/samples/06_jpeg_decode provide more information on how to use this API.
