◆ xvmc_id
| 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.
- application - set during initialization
- libavcodec - unchanged
Definition at line 54 of file xvmc.h.
◆ data_blocks
| 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.
- application - set the pointer during initialization
- libavcodec - fills coefficients/pixel data into the array
Definition at line 63 of file xvmc.h.
◆ mv_blocks
| XvMCMacroBlock* xvmc_pix_fmt::mv_blocks |
Pointer to the macroblock description array allocated by XvMCCreateMacroBlocks() and freed by XvMCDestroyMacroBlocks().
- application - set the pointer during initialization
- libavcodec - fills description data into the array
Definition at line 70 of file xvmc.h.
◆ allocated_mv_blocks
| int xvmc_pix_fmt::allocated_mv_blocks |
Number of macroblock descriptions that can be stored in the mv_blocks array.
- application - set during initialization
- libavcodec - unchanged
Definition at line 77 of file xvmc.h.
◆ allocated_data_blocks
| int xvmc_pix_fmt::allocated_data_blocks |
Number of blocks that can be stored at once in the data_blocks array.
- application - set during initialization
- libavcodec - unchanged
Definition at line 83 of file xvmc.h.
◆ idct
Indicate that the hardware would interpret data_blocks as IDCT coefficients and perform IDCT on them.
- application - set during initialization
- libavcodec - unchanged
Definition at line 90 of file xvmc.h.
◆ unsigned_intra
| int xvmc_pix_fmt::unsigned_intra |
In MoCo mode it indicates that intra macroblocks are assumed to be in unsigned format; same as the XVMC_INTRA_UNSIGNED flag.
- application - set during initialization
- libavcodec - unchanged
Definition at line 97 of file xvmc.h.
◆ p_surface
| XvMCSurface* xvmc_pix_fmt::p_surface |
Pointer to the surface allocated by XvMCCreateSurface().
It has to be freed by XvMCDestroySurface() on application exit. It identifies the frame and its state on the video hardware.
- application - set during initialization
- libavcodec - unchanged
Definition at line 105 of file xvmc.h.
◆ p_past_surface
| XvMCSurface* xvmc_pix_fmt::p_past_surface |
Set by the decoder before calling ff_draw_horiz_band(), needed by the XvMCRenderSurface function.
Pointer to the surface used as past reference
- application - unchanged
- libavcodec - set
Definition at line 114 of file xvmc.h.
◆ p_future_surface
| XvMCSurface* xvmc_pix_fmt::p_future_surface |
Pointer to the surface used as future reference.
- application - unchanged
- libavcodec - set
Definition at line 120 of file xvmc.h.
◆ picture_structure
| unsigned int xvmc_pix_fmt::picture_structure |
top/bottom field or frame
- application - unchanged
- libavcodec - set
Definition at line 126 of file xvmc.h.
◆ flags
| unsigned int xvmc_pix_fmt::flags |
XVMC_SECOND_FIELD - 1st or 2nd field in the sequence.
- application - unchanged
- libavcodec - set
Definition at line 132 of file xvmc.h.
◆ start_mv_blocks_num
| int xvmc_pix_fmt::start_mv_blocks_num |
Number of macroblock descriptions in the mv_blocks array that have already been passed to the hardware.
Definition at line 142 of file xvmc.h.
◆ filled_mv_blocks_num
| int xvmc_pix_fmt::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.
Definition at line 151 of file xvmc.h.
◆ next_free_data_block_num
| int xvmc_pix_fmt::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.
All blocks before this one have already been claimed by placing their position into the corresponding block description structure field, that are part of the mv_blocks array.
- application - zeroes it on get_buffer(). A successful ff_draw_horiz_band() may zero it together with start_mb_blocks_num.
- libavcodec - each decoded macroblock increases it by the number of coded blocks it contains.
