Gpu Jpeg Encoder

Parallel computing could be applied to all stages both of jpeg encoder and jpeg decoder.

Gpu jpeg encoder. The most difficult part of jpeg algorithm is entropy codec and we ve accomplished that task on gpu as well. The nvjpeg2000 library is for decoding jpeg 2000 format images. The jpeg gpu project aims to solve both these problems by shifting the decode computation as early as possible to the gpu. To create high performance jpeg encoder for high speed video applications we have also done algorithm optimization for gpu calculations.

Next generation software solutions for live video encoding and transcoding. Applications that rely on nvjpeg or nvjpeg2000 for decoding deliver higher throughput and lower latency compared to cpu only decoding. Lossy jpeg compression algorithm meets all criteria for parallel computations on the gpu. This is full performance oriented implementation of baseline jpeg.

These are the latest performance benchmarks for encoding of 2k and 4k images 24 bit jpeg compression on gpu without deviceio latency single image mode no batch no streaming on nvidia geforce gtx 1080 ti and quadro p6000. Martin srom cesnet z s p o description. Image partitioning to a big amount of 8 8 or 16 16 blocks is a key feature to speedup jpeg codec on gpu. Partially decoded jpeg data is uploaded as soon as the entropy coded symbols are read and a set of pre defined shaders complete the rest of the decode into a gpu texture.

That encoding time corresponds to jpeg compression performance around 60 gb s.
