when broadcast is turned off, FFMPEG does not terminate

Description

When I turn off the broadcast, only a client watching with the local ip remains. In my opinion, when the OBS broadcast is turned off, FFMPEG does not terminate and remains as a local viewer.

Replay

Step 1: I'm streaming using Ffmpeg on SRS. This screenshot is while broadcasting

Step 2: When I turn off the broadcast, only a client watching with the local ip remains. In my opinion, when the OBS broadcast is turned off, FFMPEG does not terminate and remains as a local viewer.

Expect

Once the broadcast is closed, all FFMPEG broadcasts related to the broadcast must also be terminated.
