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 (...) -
Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Open VideoStream using OpenCV 4.5.1 works on Windows but fails on Docker python:3.9.2-slim-buster for specific IP cam
18 mai 2021, par Qua285I have 2 ip cameras - one of Hikvision and another of Provision ISR. Both use Onvif and work on VLC.
I've written a simple python script to record images every 5 sec from their video stream.
On Windows 10, using VSCode they both work as expected. Once deployed to a Docker container, my script works as expected with the Hikvision but fails with the Provision ISR - it doesn't open the stream.


Running
python -c "import cv2; print(cv2.getBuildInformation())"on windows (venv 3.9.2) and on docker machine bring slightly different results but it's beyond my understanding to take something out of it...
Here is the Windows one :

If relevant, this is the dockerfile I've used to build the image :

RUN apt-get install ffmpeg libsm6 libxext6 -y

and last, this is the script code (simplified) :

ffmpeg x11grab to streamable format
2 juin 2021, par Jintor2 FFMPEG process


(1) generating a ffmpeg x11grab to a .mp4
(2) take the .mp4 and restream it simultaneously to multiple rtmp endpoints


ISSUE the generated file in (1) have this error "moov atom not found"


This is the command that generate (1) :


ffmpeg -re -y -f x11grab -draw_mouse 0 -framerate 30 
-video_size $RESOLUTION -i :$DISPLAY_NUM -c:a aac -c:v libx264 
-movflags +faststart -preset ultrafast -crf 28 -refs 4 -qmin 4 
-pix_fmt yuv420p -filter:v fps=30 file.mp4


in the (2) => when I try to ffmpeg -i file.mp4 output somewhere : I get "moov atom not found" so the (2) can't read or open (1).


What I'm I missing


in (1)
-movflags +faststartdoesn't seem to fix the issue

••••••• EDIT : more details on the context ••••••


I'm using openvidu : webrtc with kurento and coturn.


The record feature creates a .mp4 on the fly as the chat is going on.


To start the recording, there is an API call i can make to my server and it automatically stops when all users leaves the chatroom OR do an other api call to stop. see composed video in this link https://docs.openvidu.io/en/2.17.0/advanced-features/recording/


openvidu have also webhooks.


My problem is not how to stop ffmpeg, but getting FFMPEG to encode while the mp4 or other is being generated "on the fly".


There is 2 options :


OPTION 1 : individual => 1 .webm per camare => this .webm ffmpeg can restream as hls or RTMP => it's working.


OPTION 2 : ** but the issue is with "Composed" video => it's using ffmpeg to x11grab the session... but it's mp4 without moov ato, so ffmpeg don't do anything with this.


see the composed.sh script here
https://github.com/OpenVidu/openvidu/blob/master/openvidu-server/docker/openvidu-recording/scripts/composed.sh


***************** EDIT 3 *************


in the .sh this is the part that is creating the mp4


ffmpeg -y -f alsa -i pulse -f x11grab -draw_mouse 0
-framerate $FRAMERATE -video_size $RESOLUTION -i :$DISPLAY_NUM
-c:a aac -c:v libx264 -preset ultrafast
-crf 28 -refs 4 -qmin 4 -pix_fmt yuv420p
-filter:v fps=$FRAMERATE "/recordings/$VIDEO_ID/$VIDEO_NAME.$VIDEO_FORMAT"


How can I modify this to have better result example VP8 or VP9 with good quality .webm so that the ffpmeg second command(2) can encode it live...


**** EDIT 4 ********


I tried this it worked for 30 seconds and suddenly stopped


<./stop ffmpeg -y -f alsa -i pulse -f

Dash.js not playing mpd files made with ffmpeg
31 décembre 2022, par MacsterI'm using ffmpeg to create chunks and manifest of a webm file which I want to live stream with Dash.js. Unfortunately Dash.js won't play the mpd file, no matter which way I create the chunks and manifest. However, the sample mpd URL from Dash.js is working.

UPDATE


Well, it seems like the problem in general was, that the mpd's wouldn't play from that /dash folder. So i took a look into the code and found a bad routing. Anyways, the mpd would't start with the given command I used, probably becasue it creates a
dynamicmanifest, like @Markus Schumann says. So I'm going with a new one which seems to be working for now, but not very well.
