  • Support de tous types de médias

    10 avril 2011

  • How to load test FFMPEG streams to NGINX RTMP server without Server error : Already publishing ?

    23 novembre 2022, par Nav

    My objective is to have an EC2 server running NGINX with RTMP module, and another EC2 server running multiple FFMPEG processes in the background, which stream a video to the first EC2 server. The video is stored on the second EC2 server. The idea is to measure the amount of CPU and RAM consumed and to see if the streaming fails at any point due to the server being overloaded. This would help identify the load a server can support, and help decide how many servers are required when handling n number of simultaneous users.

    


    This is the script I tried using :

    


    #!/usr/bin/env bash&#xA;for i in {1..10}; do&#xA;    ffmpeg -nostdin -re -i myVideo.mp4 -c:v copy -c:a aac -ar 44100 -ac 1 -f flv rtmp://<first server="server" ipv4="ipv4" address="address">/mystream &amp;&#xA;done;&#xA;</first>

    &#xA;

    When running the script, I get this error :

    &#xA;

    Stream mapping:&#xA;  Stream #0:0 -> #0:0 (copy)&#xA;  Stream #0:1 -> #0:1 (aac (native) -> aac (native))&#xA;[rtmp @ 0x55a0c3a4bc0] Server error: Already publishing&#xA;rtmp://<ip address="address">/mystream: Operation not permitted&#xA;[rtmp @ 0x55d9d5bc0c0] Server error: Already publishing&#xA;rtmp://<ip address="address">/mystream: Operation not permitted&#xA;Stream mapping:&#xA;  Stream #0:0 -> #0:0 (copy)&#xA;  Stream #0:1 -> #0:1 (aac (native) -> aac (native))&#xA;Stream mapping:&#xA;  Stream #0:0 -> #0:0 (copy)&#xA;  Stream #0:1 -> #0:1 (aac (native) -> aac (native))&#xA;Stream mapping:&#xA;[rtmp @ 0x55779e9bc0] [rtmp @ 0x55dd17e1bc0] Server error: Already publishing&#xA;Server error: Already publishing&#xA;rtmp://<ip address="address">/mystream: Operation not permitted&#xA;rtmp://<ip address="address">/mystream: Operation not permitted&#xA;  Stream #0:0 -> #0:0 (copy)&#xA;  Stream #0:1 -> #0:1 (aac (native) -> aac (native))&#xA;[rtmp @ 0x55c06b6dbc0] Server error: Already publishing&#xA;rtmp://<ip address="address">/mystream: Operation not permitted&#xA;[rtmp @ 0x56210db9bc0] Server error: Already publishing&#xA;rtmp://<ip address="address">/mystream: Operation not permitted&#xA;</ip></ip></ip></ip></ip></ip>

    Should I use different ports for each FFMPEG streaming command ? So I'd have to enable a range of ports on the EC2 instance and specify a different port in the URL of the FFMPEG RTMP command and also allow multiple ports in NGINX-RTMP config ? Does anyone know a good way to do load testing for RTMP without errors ? How would I know if the server is unable to handle the load ? Would packets start dropping ? How would it be measured ? It's not necessary to use FFMPEG. Anything is fine, but tools like Apache Bench don't seem to be for RTMP.

  • How to run python when I receive post request

    28 septembre 2021, par BigJ

    I made python code for capture the image from rtsp streaming server using ffmpeg. I want to make api that when I receive POST request include rtsp address in message, then run python file using with the rtsp address. Like running child-process.
    &#xA;I'm using loopback(typescript) for api developing.
    &#xA;Can you recommend useful library or sample code ??
