Macro Definition Documentation

BLOCK_ALIGN

#define BLOCK_ALIGN   32

Initial memory alignment of data block.

Note

This must be a multiple of sizeof(void*) and a power of two. libavcodec AVX optimizations require at least 32-bytes.

BLOCK_PADDING

#define BLOCK_PADDING   32

Initial reserved header and footer size.
