Key Features and Enhancements#

  • Removed NVIMGCODEC_EXT_API_VER. From now on, extensions versioning is base on NVIMGCODEC_VER instead

  • Added support for nvJpeg2000 v0.9.0:

    • Enabled HT jpeg2000 encoding

    • Enabled int16 encoding

    • Enabled new quality types: Q-Factor (can be used via NVIMGCODEC_QUALITY_TYPE_QUALITY) and Quantization step

  • Added support for nvTiff v0.5.1:

    • Enabled CUDA tiff encoder

  • Added support for CUDA 12.9

  • Upgraded OpenJpeg to v2.5.3

  • Added support for multi-image decoding.

  • Added nvimgcodecCodeStreamInfo_t and nvimgcodecCodeStreamView_t types to C API.

  • Moved region field from nvimgcodecImageInfo_t to nvimgcodecCodeStreamView_t.

  • Removed DecodeSource from Python API. Use CodeStream.getSubCodeStream instead.

  • Changed quality steering mechanism and added new quality types:

    • use quality_type and quality_value to specify quality

    • quality and target_psnr were removed

  • Allow encoding images with padded rows in Python.

  • Added support for BigTiff decoding

  • Added support for metadata extraction from tiff files (Currently only nvTiff is supported)

    • GeoTiff metadata extraction

    • Medical - Philips metadata extraction

    • Medical - Aperio metadata extraction

Fixed Issues#

  • Fixed race condition on CPU decoders with GPU memory outputs

  • Use ZLIB_FOUND, JPEG_FOUND CMake variables to determine if ZLIB and JPEG are available

  • Fixed Python encode and write freeze when no valid images were passed

  • Fixed Python decode and read abort when passing only None

  • Fixed Python decode and read segfault when passing None as element of a batch

Deprecated features#

  • Support for CUDA 11 will end in the next release.

  • Support for Python 3.8 will end in the next release

  • Support for Maxwell, Volta, Pascal GPUs will end in the upcoming releases.
