The reproduction method is as follows:
When I start streaming and play the FLV file, then close one of the origin processes, the FLV file can no longer be played.

After you close the process, did the stream stop? Can you continue playing by refreshing the page after restarting the stream?

Thank you for your reply! After I closed the process, the stream still continued to push because I have two origins. The other one should still have the stream as it is set in the edge to have the stream from those two origins. When one process is closed, it should go to the other one that is still running. Also, even after refreshing the page, I still cannot play it.
