Video Encode Drivers for RTOS and Safety Critical Systems


CoreAVI's EncodeCore™ is a real time and safety critical H.264 video encode driver that enables the hardware video encoder that is built-in modern graphics and system on chip processors. This driver allows applications to encode raw video images with much lower CPU usage and power consumption than would be possible with a software-only encoder. CoreAVI’s video encode drivers are deployed in airborne display systems to encode the graphics/video output enabling a

pplications requiring recoding, low bandwidth transmission and other capabilities were compressed video is required.

The video encode driver operates with CoreAVI’s ArgusCore™ ES/SC2 (CoreAVI’s family of OpenGL graphics libraries) graphics drivers.  The driver architecture and API ensures high efficiency and low latency between the graphics hardware and the video encode hardware.  The resulting compressed video is made available on the host single board computer as raw H.264 data.  The raw H.264 data can then be packaged by the application into a desired format that can be transmitted, recorded and played back on video players supporting the packaged format.
