Macros | |
#define | APPEND_IF_NONZERO(field, str, name) |
#define | APPEND_IF_NOT_H264_UNSET(field, str, name) |
#define | DETERMINE_JOINT(joint, attr1, attr2, field) (joint->field = (attr1 && attr1->field) ? attr1->field : (attr2 && attr2->field) ? attr2->field : 0) |
#define | H264_ATTR_KEY_UNSET UINT8_MAX |
Value that indicates an attribute is actually unset. | |
#define | H264_MAX_SPS_PPS_SIZE 16 |
Maximum size for SPS / PPS values in sprop-parameter-sets attribute if you change this value then you must change H264_MAX_SPS_PPS_SIZE_SCAN_LIMIT as well. | |
#define | H264_MAX_SPS_PPS_SIZE_SCAN_LIMIT "15" |
This is used when executing sscanf on buffers of H264_MAX_SPS_PPS_SIZE length. It must ALWAYS be a string literal representation of one less than H264_MAX_SPS_PPS_SIZE. | |
