How to load test FFMPEG streams to NGINX RTMP server without Server error : Already publishing ?
23 novembre 2022, par NavMy 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
nnumber of simultaneous users.

This is the script I tried using :


#!/usr/bin/env bash
for i in {1..10}; do
 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 &
done;
</first>

When running the script, I get this error :


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

rtmp://<ip address="address">/mystream: Operation not permitted

[rtmp @ 0x56210db9bc0] Server error: Already publishing
rtmp://<ip address="address">/mystream: Operation not permitted
</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.

Separating webserver and processing server
6 mars 2020, par John DoeI would like an architecture design advice.
I have a projet composed of a public Node.JS API server (handling client HTTP browser requests)
The purpose of my project is to convert an image to a video (I do this using ffmpeg as CLI and it can take some time)
The business workflow should be the the following :
1) A user sends an image URL and his email (as POST parameters) to the API
2) The API should responds "OK 200" and send later an email containing a video of the image
Here is my idea (and what my current program does) :
1) The nodeJS API directly responds "OK 200" to the client
2) The nodeJS server asynchronously downloads the image using npm axios library, then saves that image to current directory, then asynchronously launchs a heavy tool that convert
the image to a video (can take some time), then sends an email to the client.In my design everything occurs on the same server (NodeJS API).
I think this isn’t a good design at all and I should separate the Nodejs HTTP API and the heavy tasks video processing server.
However, this separation means communicating image from a server to another one and i don’t know how to do that.I think there are useful services that I could use on AWS but I don’t know which one and how.
Would it be possible to help me in the design of this application (and which cloud services could I use ?)

How to run python when I receive post request
28 septembre 2021, par BigJI 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.

I'm using loopback(typescript) for api developing.

Can you recommend useful library or sample code ??
