Smart encoding improvements for embedded vision solutions
Intel® Media SDK provides a cross-platform API for developing media applications on Windows* and Embedded Linux*. And the new release, Intel Media SDK 2017 R2 for Embedded Linux*, delivers great improvements to help developers build embedded vision solutions with smart encoding capabilities.
New Features
Among the key features this release enables is the Region of Interest (ROI) for HEVC encoder in constant and variable bitrate modes. Developers can now control the compression rate of specific rectangular regions in input stream while keeping the bitrate target. This makes it possible, for example, to reduce compression of the areas where the viewer needs to see more details (e.g. faces or number plates), or to inrease it for the background with complicated texture that otherwise would consume majority of the bandwidth. ROI can also be used to put a privacy mask on certain regions that have to be blurred (e.g. logos or faces).

This release also brings video wall compositing enhancments including improved performance and support for non-uniform tiles (available in updated Intel Media SDK API 1.24).
Video Wall
Both enhancements provide more control and flexibility to smart cameras and network video recorders (NVRs) developers targeting Intel platforms.
