ffmpeg – What causes ‘Error number -10054’ while listening to an RTMP stream using PyAV in Python?

When I use PyAV to listen a rtmp stream

import av,cv2
container = av.open('rtmp://localhost:1935/stream/live',options={'listen': '1'})
for frame in container.decode(video=0):
    frame = frame.to_ndarray(format="bgr24")
    cv2.imshow('live',frame)
    cv2.waitKey(1)

I use this ffmpeg command to push stream:

ffmpeg -re -i "live.flv" -c copy -f flv "rtmp://localhost:1935/stream/live"

ffmpeg exited with this error:

and python exited without any error.

I tried OBS to push the stream,but I got the same result

This may be a problem with PyAV
