FFmpeg Remap Filter on GPU
In a standard FFmpeg we see several filters for video remap: v360 (11.213) and remap (11.164). These Remap Filters on CPU from FFmpeg are very slow. Nevertheless, remap filter could be performed much faster on GPU. We've implemented that filter on NVIDIA GPU with Fastvideo SDK and it's working very fast even on laptop GPUs. On professional GPUs we can decode, remap and encode multiple video streams with high performance and minimum latency.

JPEG Optimizer Library on CPU and GPU
The idea about image optimization is very popular and it really makes sense. As soon as JPEG is so widespread at web, we need to optimize JPEG images for web as well. By decreasing image size, we can save space for image storage, minimize traffic, improve latency, etc.
Fast RAW Compression
Recording performance for RAW data acquisition task is essential issue for 3D/4D, VR and Digital Cinema applications. Quite often we need to do realtime recordings to portable SSD and here we face questions about throughput, compression ratio, image quality, recording duration, etc. As soon as we need to store RAW data from a camera, the general approach for raw image encoding is not exactly the same as for color. Here we review several methods to solve that matter.
