ffmpeg exits after video is played

Describe the bug
Hi,

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

#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

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.

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.

First of all, this issues is entirely a bug of FFmpeg, not SRS. It fails to handle the EOF event, and leads to the failure of loop ingesting file stream.

Second, you should never rely on FFmpeg for IO handling and error handling, because FFmpeg is too complex to handle all events correctly and without bugs. Therefore, you must manage the FFmpeg, restarting it if it gets stuck or fails to run, like what SRS Stack does.
