| int xvmc_pix_fmt::xvmc_id |
The field contains the special constant value AV_XVMC_ID.
It is used as a test that the application correctly uses the API, and that there is no corruption caused by pixel routines.

| short* xvmc_pix_fmt::data_blocks |
Pointer to the block array allocated by XvMCCreateBlocks().
The array has to be freed by XvMCDestroyBlocks(). Each group of 64 values represents one data block of differential pixel information (in MoCo mode) or coefficients for IDCT.
