streamlit-webrtc: Problem with RECVONLY reconnections

Hi, when I stop and start video files/streams, using RECVONLY, it doesn’t work. It starts the video correctly, but when I stop and start again, it shows only a gray screen.

The log is:

2021-05-17 12:27:14.093 ICE connection state is closed

How can I solve it?
