j2k to h264

JPEG2000 Transcoding to H.264 on GPU

We have implemented fast transcoding software to transform JPEG2000 streams on the fly to h264. This is fully parallel and performance-oriented implementation of JPEG2000 algorithm. We got fast JPEG2000 compression and decompression on NVIDIA GPU due to parallel implementation and thorough optimization of JPEG 2000. Our JPEG2000 video codec on CUDA is definitely one of the fastest J2K codecs on the market.
