bef_effect_ai_chroma_keying.h
CV480 针对bef_ai_chroma_keying_uniform_type 新增3个参数：BEF_AI_CHROMA_KEYING_UNIFORM_CONTRAST、BEF_AI_CHROMA_KEYING_UNIFORM_BRIGHTNESS 和 BEF_AI_CHROMA_KEYING_UNIFORM_OPACITY
typedef enum{
BEF_AI_CHROMA_KEYING_UNIFORM_COLOR = 0, // COLOR：[0,360]，算法会自动调色，可以手动更改微调绿幕主色
BEF_AI_CHROMA_KEYING_UNIFORM_INTENSITY = 1, // INTENSITY：[0,1]，抠图强度，以COLOR为中心，影响抠除色域的范围
BEF_AI_CHROMA_KEYING_UNIFORM_SPILL = 2, // SPILL：[0,1]，去溢色能力，对于绿幕，会把前景里泛绿的颜色矫正
BEF_AI_CHROMA_KEYING_UNIFORM_EDGE_SMOOTH = 3, // EDGE_SMOOTH：[0,1]，边缘平滑能力，适当的值可以去锯齿，值过大可能会导致前景模糊
BEF_AI_CHROMA_KEYING_UNIFORM_DETAIL = 4, // DETAIL：[0,1]，细节增强能力，0为通用方案，1为精细方案，之间进行效果加权
BEF_AI_CHROMA_KEYING_UNIFORM_SHADOW = 5, // SHADOW：[0,1]，阴影增强能力，可用于保留阴影

bef_effect_ai_facefitting.h
CV480更新最大支持人脸数，BEF_FITTING_MAX_FACE 从6更新为10

CV480之前的版本：
#define BEF_FITTING_MAX_FACE 6 //最大支持的人脸数
bef_effect_ai_hairparser.h
CV480新增bef_effect_ai_hairparser_get_output_shape_with_input
/*

bef_effect_ai_online_license.h
CV480新增bef_effect_ai_free_online_license_auth_msg 和 bef_effect_ai_free_device_id
//释放auth_msg内存，如果调用过 bef_effect_ai_get_online_license_authmsg，在鉴权后调用该接口
BEF_SDK_API int bef_effect_ai_free_online_license_auth_msg(char* auth_msg);
