Appendix G. XvMC Support

This release includes support for the XVideo Motion Compensation (XvMC) version 1.0 API on GeForce 6 series and GeForce 7 series add-in cards, as well as motherboard chipsets with integrated graphics that have PureVideo support based on these GPUs. There is a static library, "libXvMCNVIDIA.a", and a dynamic one, "", which is suitable for dlopening. XvMC's "IDCT" and "motion-compensation" levels of acceleration, AI44 and IA44 subpictures, and 4:2:0 Surfaces up to 2032x2032 are supported.

libXvMCNVIDIA observes the XVMC_DEBUG environment variable and will provide some debug output to stderr when set to an appropriate integer value. '0' disables debug output. '1' enables debug output for failure conditions. '2' or higher enables output of warning messages.
