Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -
Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs
12 avril 2011, parLa manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

Multiple live video outputs advice. Live stream/Record/Preview, FFMPEG, Windows, Decklink [closed]
18 septembre 2024, par stroltzI am looking for advice on how best to achieve multiple live video outputs.


The live source is a Decklink card on Windows. (We have a ffmpeg build working to access the card) We want 4 outputs ;


- 

-
We want to run a preview window (low quality would be preferred) just so the user can see the video is working.


-
We want to be able to live stream - single bit rate, RTMP. (goes up to a CDN)


-
Independent from the streaming we want to be able to stop and start recording to file. Ideally using CRF. So a separate encode – but maybe we use the RTMP encode, not sure, and do 1 x encode only.


-
We also want to save a separate audio file. Stops and starts at the same time as the video file above (if required we could do this as a post process on the video file we make above)












We want to keep CPU use down to as reasonable as possible. (so no high end hardware)


We have had a suggestion of this with ffmpeg ;


Input >> ffmpeg


- 

- split input to main and monitoring ;
- scale monitoring stream to lower resolution
- encode both streams
- provide both outputs to local streaming server
ffmpeg >> local streaming server
- use API to start and stop recordings (or web console, if you do it manually)
- provide streams to CDN or/and provide access to your streams for end users














recorded files >> another ffmpeg (controlled by some script that get
RECORDING COMPLETED event to start ffmpeg process)


- 

- extract audio from recorded file
- save audio into file






Which sounds possible, but if doing that, which local streaming server would work best (open source, API...)


or open to other ideas as to the best way.


https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs shows lots of ways, but I don't think you get to control the individual outputs independently.

I want to record my computer screen and stream it to other computer browser over same network
25 décembre 2022, par Abdullah QasimI am using Flask for this purpose. I wanted to create a rtmp server that stream the screen in web browser.


My Python Code is :


import os
import subprocess

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def index():
 return render_template('index.html')

if __name__ == '__main__':
 # Start the RTMP server in a separate process
 subprocess.Popen(['ffmpeg', '-f', 'gdigrab', '-framerate', '25', '-probesize', '100000000000', '-i', 'desktop', '-vcodec', 'libx264', '-preset', 'ultrafast', '-tune', 'zerolatency', '-f', 'flv', 'rtmp://localhost:5000/live/stream_name'])

 # Start the Flask app
 app.run()



My HTML code is :



 
 
 
 <code class="echappe-js"><script src="https://unpkg.com/video.js/dist/video.js"></script>
 
 
 
<script>&#xA; var player = videojs(&#x27;my-video&#x27;);&#xA; </script>
 




When I run the flask app it produces an error :
