def img2video(src_path, outputname="video.avi"):

for filename in file_list:

左右拼接图像转视频
如果要左右拼接图像，并转为视频，可以使用如下代码片段
from PIL import Image
a_img = Image.open(filename)
b_img = Image.open(dstfile)
dst = Image.new('RGB', (a_img.width * 2, a_img.height))
dst.paste(a_img, (0, 0))
dst.paste(b_img, (a_img.width, 0))
videoWriter.write(cv2.cvtColor(np.array(dst), cv2.COLOR_RGB2BGR))
