Description: Generic library support script
This is GNU libtool, a generic library support script. Libtool hides the complexity of generating special library types (such as shared libraries) behind a consistent interface. To use libtool, add the new generic library building commands to your Makefile,, or See the documentation for details. Libtool supports building static libraries on all platforms.

Description: Video Acceleration (VA) API for Linux — development files
Video Acceleration API (VA API) is a library (“libVA”) and API specification which enables and provides access to graphics hardware (GPU) acceleration for video processing on Linux and UNIX based operating systems. Accelerated processing includes video decoding, video encoding, subpicture blending and rendering. The specification was originally designed by Intel for its GMA (Graphics Media Accelerator) series of GPU hardware, the API is however not limited to GPUs or Intel specific hardware, as other hardware and manufacturers can also freely use this API for hardware accelerated video decoding.

Description: Video Decode and Presentation API for Unix (development files)
VDPAU (Video Decode and Presentation API for Unix) is an open source library (libvdpau) and API designed by NVIDIA originally for its GeForce 8 series and later GPU hardware, targeted at the X Window System on Unix operating-systems (including Linux, FreeBSD, and Solaris). This VDPAU API allows video programs to offload portions of the video decoding process and video post-processing to the GPU video-hardware.
