This release includes support for the XVideo Motion Compensation (XvMC) version 1.0 API on the GeForce 5 series, the GeForce 6 series and the GeForce 7 series. There is a static library "libXvMCNVIDIA.a" and a dynamic one "libXvMCNVIDIA_dynamic.so" 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.
