JPEG Codec

    JPEG Encoder and Decoder:

JPEG encoder and decoder are separate libraries.
    The main features of JPEG decoder features:
  1. Support both baseline and progressive scan mode;
  2. It can decode JPEG file in all sampling formats:
    • YUV 400 format (grey scale image)
    • YUV 420 format (color image)
    • YUV 411 format (color image)
    • YUV 422 format (color image)
    • YUV 444 format (color image)
  3. The output of the decoder will always be YUV 444 format.
  4. Only one single API function is needed to decode an image.
  The main features of JPEG encoder features:
  1. The input raw image will be uncompressed YUV or RGB images;
  2. The encoder accepts following 13 input formats:
    • IMAGE_FORMAT_YUV_400 = 1, (grey scale image)
    • IMAGE_FORMAT_PACKED_YUV_420 = 2,
    • IMAGE_FORMAT_PACKED_YUV_411 = 3,
    • IMAGE_FORMAT_PACKED_YUV_422 = 4,
    • IMAGE_FORMAT_PACKED_YUV_444 = 5,
    • IMAGE_FORMAT_PACKED_RGB_444 = 6,
    • IMAGE_FORMAT_PACKED_BGR_444 = 7,
    • IMAGE_FORMAT_PLANAR_YUV_420 = 8,
    • IMAGE_FORMAT_PLANAR_YUV_422 = 9,
    • IMAGE_FORMAT_PLANAR_YUV_444 = 10,
    • IMAGE_FORMAT_PLANAR_RGB_444 = 11,
    • IMAGE_FORMAT_PLANAR_BGR_444 = 12
  3. The image quality can be set to level 1 to 100 (100 is the best quality).
  4. Only one single API function is needed to encode an image.
