我有一个python脚本,应使用以下功能运行ffmpeg命令:
def transcode(in_path, out_path):
cmd = ["ffmpeg", "-y", "-i", in_path, '-vf smartblur=lr=1']
cmd += ["-an", out_path]
print("Running:", " ".join(cmd))
subprocess.run(cmd, stdout=cmdout, stderr=cmdout)
当我运行python脚本时,它失败并出现以下ffmpeg错误:
Running: ffmpeg -y -i raid/orig/scenes/train/5786088.mp4 -vf smartblur=lr=1 -an raid/4K/scenes/train/5786088.mp4

Error splitting the argument list: Option not found
您可以在第一行中看到它尝试执行的命令,当我在命令行中运行它时,它可以正常运行。当我在外壳中运行命令时,它会输出与上面的错误相同的ffmpeg版本和参数。
我觉得我错过了一些简单而又至关重要的事情,任何人都可以指出我正确的方向吗?

您可能必须像这样拆分“ -vf smartblur”选项:
cmd = ["ffmpeg", "-y", "-i", in_path, '-vf', 'smartblur=lr=1']
