1. 问题
使用如下脚本，将.HEIC文件转化成.jpg文件时，报错： `python from PIL import Image import whatimage
import pyheif
import glob import time import os import cv2
heic_img_path = './IMG_6915.HEIC' save_path = heic_img_path[:-5] + ".jpg" print('111') with open(heic_img_path, 'rb') as f: heic_img = f.read() print('222')
确认图片真实格式
img_format = whatimage.identify_image(heic_img) print('img_format = ', img_format) if img_format in ['heic']: # 读取文件内容 img = pyheif.read(heic_img) print('img:', img) # 重新写入文件并保存 pi = Image.frombytes(mode=img.mode, size=img.size, data=img.data) pi.save(save_path, format="jpeg") print('save_path:', save_path) `
报错为： ` import pyheif File "/Users/lib/python3.7/site-packages/pyheif/init.py", line 4, in import _libheif_cffi import _libheif_cffi ImportError: dlopen(/Users/lib/python3.7/site-packages/_libheif_cffi.abi3.so, 2): Symbol not found: _heif_brand_to_fourcc Referenced from: /Users/lib/python3.7/site-packages/_libheif_cffi.abi3.so Expected in: flat namespace in /Users/lib/python3.7/site-packages/_libheif_cffi.abi3.so
Process finished with exit code 1
`
2. 问题原因
python调用pyheif时，缺少C++的可执行文件
