1. The configuration of SRS is as follows (Config):

  ingest test2local {
    enabled           on;
    input {
      type            stream;
**url             rtsp://address:6301/pss/111;**
    }
    ffmpeg            /usr/local/bin/ffmpeg;

    }
  }

Replay

How to replay bug?

Steps to reproduce the bug

How to replay bug?

1. Start the collection and push the stream to the local vhost for a period of about 12-24 hours.
2. SRS becomes unresponsive, leading to a complete crash of the system.

On the basis of SRS, how can we modify it to accept RTSP streams?

This is my configuration: SRS parameters (but the streaming fails rtsp://IP:1935/live/test1)

According to the configuration in srs.conf, use ffmpeg to push the stream: ffmpeg -re -i 4k.mp4 -vcodec copy -codec copy -f rtsp rtsp://210.37..:554/live/rtsp

Both SRS 3.0 and 4.0 are experiencing the same error.

Does SRS support RTSP?

Both SRS3.0 and 4.0 have the same error.

Hello, may I ask if the issue has been resolved? I am encountering the same problem.

In actual scenarios, there is no need to promote RTSP, so the RTSP server will be removed in the future.

The camera does not support pushing RTSP streams to SRS. It only supports Ingest/FFmpeg to pull RTSP streams from the camera and then forward them to SRS. Please refer to: #2304 (comment)
