ffmpeg exits after video is played

[streamingsystems]

Describe the bug Hi,

I think I found another issue where ffmpeg is crashing when the video is completed similar to this issue:

https://github.com/ossrs/srs/issues/3803

After a video is played ffmpeg exists with this:

av_interleaved_write_frame(): Broken pipeq=-1.0 size= 36024kB time=00:02:37.73 bitrate=1870.9kbits/s speed= 1x [flv @ 0x7fb3d4106880] Failed to update header with correct duration.

In issue 3803 it was a problem with ffmpeg but you were able to make a change to the server to work around this issue.

Version Latest To Reproduce

1. Download and extract the the ZIP file that contains 4 videos:

https://www.dropbox.com/scl/fi/q9wlzlafb75obu84e64v0/ffmpeg-map.zip?rlkey=7ahs16533ghdnfvddl51or0z6&dl=0

2. Run this command:

ffmpeg -stream_loop -1 -re -i 1.mp4 -stream_loop -1 -re -i 2.mp4 -stream_loop -1 -re -i 3.mp4 -stream_loop -1 -re -i 4.mp4 -map 0 -c copy -f flv rtmp://127.0.0.1:1935/live/map_0 -map 1 -c copy -f flv rtmp://127.0.0.1:1935/live/map_1 -map 2 -c copy -f flv rtmp://127.0.0.1:1935/live/map_2 -map 3 -c copy -f flv rtmp://127.0.0.1:1935/live/map_3

The video is 2m 38s long, when it reaches the end ffmpeg exits due to "Broken pipe".

Expected behavior

Ffmpeg should start over and loop the video forever.
