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

| Plugin | Description |
|---|---|
| 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.
