Chapter 42. Multimedia Libraries and Drivers

libvdpau-va-gl-0.4.2

Introduction to libvdpau-va-gl

The libvdpau-va-gl package contains a library which implements the VDPAU library. Libvdpau_va_gl uses OpenGL under the hood to accelerate drawing and scaling and the VA-API (if available) to accelerate video decoding. For now VA-API is available on some Intel chips, and on some AMD video adapters with the help of the libvdpau driver.

This package is known to build and work properly using an LFS 12.1 platform.
