使用imageio.mimwrite将numpy数组保存到io.BytesIO对象时，出现“ OSError：[Errno 32]管道损坏”

如何解决使用imageio.mimwrite将numpy数组保存到io.BytesIO对象时，出现“ OSError：[Errno 32]管道损坏”

我正在尝试使用imageio.mimwrite将一个numpy数组（帧数组）另存为视频。

这样的操作效果很好-

imageio.mimwrite('./temp4.mp4',frames,fps=fps,format='.mp4')

但是，当我尝试这样的事情时-

fo = io.BytesIO()
imageio.mimwrite(fo,format='.mp4')

OR

writer = imageio.get_writer(fo,format='.mp4')

for im in frames:
    writer.append_data(imageio.imread(im))
writer.close()

我收到以下错误-

During handling of the above exception,another exception occurred:

FFMPEG STDERR OUTPUT:

使用anaconda ffmpeg和非anaconda ffmpeg会出现相同的错误。

是否可以解决此错误？

还有没有更好的方法将帧列表转换为.mp4或对其进行序列化以通过API发送？

谢谢！
