Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.
La documentation de l’utilisation du script d’installation (...) -
MediaSPIP 0.1 Beta version
25 avril 2011, parMediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
The zip file provided here only contains the sources of MediaSPIP in its standalone version.
To get a working installation, you must manually install all-software dependencies on the server.
If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...) -

Gstreamer convert and display video v4l2 - tee problems in rust
27 mars 2023, par d3imI have USB grabber v4l2 source and I want to tee stream to autovideosink and x264enc to file (now as fake black hole)


When I disable one or another branch it works but together Pipeline goes :


Pipeline state changed from Null to Ready
Pipeline state changed from Ready to Paused


and stays there never switches to Playing


gst-launch-1.0 with similar functionality works well.


gst::Element::link_many(&[&pw_video, &v_caps, &vid_queuey, &vid_tee]).unwrap();
 gst::Element::link_many(&[&vid_queue1, &autovideoconvert, &vid_queuex, &autovideosink]).unwrap();
 gst::Element::link_many(&[&vid_queue2, &autovideoconvert_x264, &vid_queue3, &x264, &vid_queue4, &fake]).unwrap();

 let tee_display_pad = vid_tee.request_pad_simple("src_10").unwrap();
 let vid_queue1_pad = vid_queue1.static_pad("sink").unwrap();

 tee_display_pad.link(&vid_queue1_pad).unwrap();

 let tee_convert_pad = vid_tee.request_pad_simple("src_20").unwrap();
 let vid_queue2_pad = vid_queue2.static_pad("sink").unwrap();

 tee_convert_pad.link(&vid_queue2_pad).unwrap();


How can I use tee in rust properly to have playable pipeline with two branches ?


Update : I read some posts about increasing queue size, so I tried for this and then all queues :


let vid_queue1 = gst::ElementFactory::make("queue")
 .name("queue1")
 .property("max-size-buffers", 5000 as u32)
 .property("max-size-bytes", 1048576000 as u32)
 .property("max-size-time", 60000000000 as u64)
 .build()
 .expect("queue1");


but it didn't help so I tried set zero latency :


let x264 = gst::ElementFactory::make("x264enc")
 .name("x264")
 .property_from_str("speed-preset", "ultrafast")
 .property_from_str("pass", "qual")
 .property_from_str("tune", "zerolatency")
 .property("quantizer", 0 as u32)
 .property("threads", 8 as u32)
 .build()
 .expect("!x264");


and it works now. But comparable gst-launch-1.0 settings didn't had such option - only queues sizes increased.


Is there any other option than setting zerolatency ?

Parse dynamic mpd file with Media Source Extensions
17 février 2023, par FrankCI just started learning about adaptive streaming, and currently I'm working on a project that needs showing a live video. In order to control some of the elements in mpd file, I determined to use MSE instead of dash.js. I refer to the code at the following URL :https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/samples/dn551368(v=vs.85)
But I found out that there is no "Initialization" tag or "range" attribute in my mpd file. I don't find any relative attribute as well. By the way I'm use nginx-rtmp + ffmpeg to generate dash file.
So here is my dash file looks like


<?xml version="1.0"?>
 
 <period start="PT0S">
 
 
 
 <segmenttimeline>
 <s t="0" d="10000"></s>
 <s t="10000" d="10000"></s>
 <s t="20000" d="5000"></s>
 <s t="25000" d="10000"></s>
 </segmenttimeline>
 
 
 
 </period>



My question is :
1.Did I have any missing parameters in using ffmpeg or nginx-rtmp resulting in losting tag in mpd file ?
2.Or there is other way to setup "Initialization"/"range" attribute and let my program work ?
3.I also curious about why my mpd file doesn't have a baseURL element ?


※My mpd file works fine with dash.js, I can see the video properly


THANKS A LOT

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 :
