X-Video Motion Compensation - Current Limitations

Current Limitations

Besides not matching all of the features and function of DxVA (which is the Microsoft equivalent API for Windows), and lacking support for other video formats than MPEG-2 in Linux device drivers from Intel and NVIDIA, the XvMC API specification version 1.0 currently also has these other limitations:

  • BOB and onefield are the only deinterlacing methods that work with XvMC.
  • Picture in Picture (PiP) does not work with XvMC.
  • Stepping through the video frame by frame can cause artifacts with XvMC.
  • Editing a video is difficult to impossible with XvMC activated.
  • Lacking network transparency in the XvMC API
  • Lacking the ability for the client application to be completely independent of which client side library needs to be used (i.e. a unified wrapper library).

A project called VA API is underway to develop a more modern video acceleration API which will support the video acceleration features of modern GPUs.

Famous quotes containing the words current and/or limitations:

    Liberty, as it is conceived by current opinion, has nothing inherent about it; it is a sort of gift or trust bestowed on the individual by the state pending good behavior.
    Mary McCarthy (1912–1989)

    ... art transcends its limitations only by staying within them.
    Flannery O’Connor (1925–1964)
