Norpix Windows CODEC
NorPix Windows codec are based on Microsoft DirectX Media Object, allowing for excellent integration to all Windows application that works with AVI.
NorPix currently provides 6 different codecs:
CODEC name | Description |
---|---|
NorPix Motion JPEG codec | CPU based. DirectShow compatible codec allowing real time compression to AVI file with Motion JPEG compression. |
NorPix H.264 codec | CPU/GPU based. DirectShow compatible codec allowing real time compression to AVI file with H.264/AVC compression. H.264/AVC codec can take advantage of Intel Quick Sync compatible processors for image resolution up to 4096x2304 pixels. |
NorPix CUDA H.264/AVC codec | GPU based. DirectShow compatible codec allowing real time compression using NVIDIA GPU to perform H.264/AVC compression. Requires an NVIDIA GPU with Maxwell or newer chipset. |
NorPix CUDA Motion JPEG codec | GPU based. DirectShow compatible codec allowing real time compression using NVIDIA GPU to perform real time JPEG compression. Up to 2.5 billion pixels monochrome or 1.5 million pixels color can be compressed real time. |
NorPix CUDA H.265/HEVC codec | GPU based. DirectShow compatible codec allowing real time compression using NVIDIA GPU to perform H.265/HEVC compression. Requires an NVIDIA GPU with Maxwell 2 or newer chipset. |
NorPix AMD H.264/AVC codec | GPU based. DirectShow compatible codec allowing real time compression using AMD GPU to perform H.264/AVC compression. Requires an AMD GPU with AMD Video Coding Engine (VCE). |
All codecs include settings to allow pattern selection for Bayer interpolation, various color balancing, automatic CPU core load balancing.
MJPEG quality factor (1 to 100% quality).
GOP size and bit rate settings for H.264/H.265 encoding.
Codecs support most image formats and sizes, the most natively as possible, reducing transcoding or image format conversion.
Native supported image formats:
BYR1: | 8bit RAW format. |
BYR2: | 12bit RAW format. |
Y8: | 8bit Gray format. |
Y16: | 12bit Gray format. |
UIVY: | UVY422 format. |
Y422: | YUV422 format. |
UVY411: | YUV411 format. |
YUV444: | YUV444 format. |
RGB555: | RGB555 format. |
RGB565: | RGB565 format. |
RGB: | RGB24 format. |
RGB32: | RGB with Alpha channel format. |
Codecs support concurrent instances, so that when using multiple cameras, all streams can be compressed in parallel.
Codecs provide FourCC selection, with default MJPEG and H.264 FourCC code (MJPG, H264). However, proprietary FourCC codes are also available to force decoders to use our codec for rendering (NPXJ, NPXH).
Codecs are not supported under Windows XP.
Performance wise, codecs run identically with or without a license code. Non-licensed versions will watermark encoded images.
