Data Fields | |
| int | xvmc_id |
| The field contains the special constant value AV_XVMC_ID. | |
| short * | data_blocks |
| Pointer to the block array allocated by XvMCCreateBlocks(). | |
| XvMCMacroBlock * | mv_blocks |
| Pointer to the macroblock description array allocated by XvMCCreateMacroBlocks() and freed by XvMCDestroyMacroBlocks(). | |
| int | allocated_mv_blocks |
| Number of macroblock descriptions that can be stored in the mv_blocks array. | |
| int | allocated_data_blocks |
| Number of blocks that can be stored at once in the data_blocks array. | |
| int | idct |
| Indicate that the hardware would interpret data_blocks as IDCT coefficients and perform IDCT on them. | |
| int | unsigned_intra |
| In MoCo mode it indicates that intra macroblocks are assumed to be in unsigned format; same as the XVMC_INTRA_UNSIGNED flag. | |
| XvMCSurface * | p_surface |
| Pointer to the surface allocated by XvMCCreateSurface(). | |
| XvMCSurface * | p_past_surface |
| Set by the decoder before calling ff_draw_horiz_band(), needed by the XvMCRenderSurface function. | |
| XvMCSurface * | p_future_surface |
| Pointer to the surface used as future reference. | |
| unsigned int | picture_structure |
| top/bottom field or frame | |
| unsigned int | flags |
| XVMC_SECOND_FIELD - 1st or 2nd field in the sequence. | |
| int | start_mv_blocks_num |
| Number of macroblock descriptions in the mv_blocks array that have already been passed to the hardware. | |
| int | filled_mv_blocks_num |
| Number of new macroblock descriptions in the mv_blocks array (after start_mv_blocks_num) that are filled by libavcodec and have to be passed to the hardware. | |
| int | next_free_data_block_num |
| Number of the next free data block; one data block consists of 64 short values in the data_blocks array. | |
| 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.
