image - 如何使用 2 个图像 ffmpeg 创建图像

Question

我想用 2 个或更多图像创建一个独特的图像，它结合了我作为参数传递的所有图像。我开始用 2 个参数证明。

    firstpart = "/home/princebot/mazos/cartas/CannonCard.png"
    secondpart = "/home/princebot/mazos/cartas/FireballCard.png"
    a = subprocess.Popen(["ffmpeg","-i", firstpart, "-filter_complex", "scale=120:-1,","-i", secondpart, "-filter_complex","hstack" , "output.png"],stdout=subprocess.PIPE)
    a.communicate()[0].decode('utf-8')

并且组合图像不创建。

假设您的规模将输出适当的尺寸使用:

a = subprocess.Popen(["ffmpeg","-i", firstpart, "-i", secondpart, "-filter_complex","[0]scale=120:-1[s];[s][1]hstack" , "output.png"],stdout=subprocess.PIPE)
