libxvmc-dev 2:1.0.12-2 (amd64 binary) in ubuntu impish

 libXvMC provides an X Window System client interface to the
 XVideo-MotionCompensation extension to the X protocol.
 .
 The XVideo-MotionCompensation extension allows for further accelerated drawing
 of videos. Video data may be sent at earlier stages of the decoding pipeline
 than raw YUV data. At the moment, driver support for XvMC is poor to
 non-existent.
 .
 This package contains the development headers for the library found in
 libxvmc1. Non-developers likely have little use for this package.
