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

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.
