(app-p) APPENDIX P: XVMC SUPPORT
__________________________________________________________________________

This release includes a libXvMCNVIDIA.a which exports the XvMC
(X-Video Motion Compensation) version 1.0 API.  This library allows
applications using XvMC to accelerate MPEG2 video at either XvMC's
"motion-compensation" or "IDCT" levels.  AI44 and IA44 subpicture
support is provided.  4:2:0 Surfaces up to 2032x2032 are supported.
This is only supported for NV17 products (GeForce4 MX).

libXvMCNVIDIA.a 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.
