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. -
Amélioration de la version de base

How to add BGM when pipe opencv images to ffmpeg - python
23 mars 2020, par karobbenBasically, I know how to stream by Pipe opencv to ffmpeg using python.
But my problem is I can’t add an audio file (BGM) for it. Does anyone know how to make it with python ?my python code is :
import cv2 as cv
import subprocess as sp
# ffmpeg command
command = ['ffmpeg',
#'-re', '-stream_loop', '-1',
#'-i', '/home/pi/scrpt/Blive/StarBucks_BGN.mp3',
'-y',
'-f', 'rawvideo',
'-vcodec','rawvideo',
'-pix_fmt', 'bgr24',
'-s', "{}x{}".format(width, height),
'-r', str(fps),
'-i', '-',
'-c:v', 'libx264',
'-pix_fmt', 'yuv420p',
'-preset', 'ultrafast',
'-f', 'flv',
rtmpUrl]I know that I can achieve this by :
sudo raspivid -o - -t 0 -w 1280 -h 720 -fps 24 -b 1000000 |
ffmpeg -re -stream_loop -1 -i "/home/pi/scrpt/Blive/StarBucks_BGN.mp3" \
-f h264 -i - -vcodec copy -r 30 -acodec aac -b:a 100k -preset ultrafast \
-tune zerolatency -f flv "rtmp://"So, I tried to add
-re -stream_loop -1 -i "/home/pi/scrpt/Blive/StarBucks_BGN.mp3"
into the python pipe, but it crashed with :[libx264 @ 0x1952aa0] using cpu capabilities: ARMv6 NEON

FFMPEG Incorrect Stream Index Matching with -var_stream_map
28 décembre 2018, par HugoI am using a bash script to run an FFMPEG command to turn an input file called
Awoo.mkv
into three HLS playlists each with a different resolution, video and audio bitrate.This is the script :
name=gw
rm /tmp/hls/*
./ffmpeg -y \
-stream_loop -1 -re \
-i Awoo.mkv \
-b:v:0 4000k -b:a:0 512k -s:0 1920x1080 -r:0 30 -g:0 90 -preset:0 superfast -tune:0 zerolatency -profile:v:0 high -level:v:0 4 \
-b:v:1 2500k -b:a:1 256k -s:1 1280x720 -r:1 30 -g:1 90 -preset:1 superfast -tune:1 zerolatency -profile:v:1 high -level:v:1 4 \
-b:v:2 800k -b:a:2 255k -s:2 960x540 -r:2 30 -g:2 90 -preset:2 superfast -tune:2 zerolatency -profile:v:2 high -level:v:2 4 \
-hls_time 6 \
-hls_list_size 2 \
-hls_flags delete_segments \
-map 0:v -map 0:a -map 0:v -map 0:a -map 0:v -map 0:a \
-var_stream_map "v:0,a:0 v:1,a:1 v:2,a:2" \
-f hls -master_pl_name "${name}.m3u8" \
-hls_segment_filename "/tmp/hls/${name}_-%d-%v.ts" \
"/tmp/hls/${name}_%v.m3u8"This almost works great, but the output is slightly off...
If you look at these two lines :
-b:v:1 2500k -b:a:1 256k -s:1 1280x720 -r:1 30 -g:1 90 -preset:1 superfast -tune:1 zerolatency -profile:v:1 high -level:v:1 4 \
-b:v:2 800k -b:a:2 255k -s:2 960x540 -r:2 30 -g:2 90 -preset:2 superfast -tune:2 zerolatency -profile:v:2 high -level:v:2 4 \A resolution of 1280x720 should have a bitrate of 2500k, a resolution of 960x540 should have a bitrate of 800k.
This is the relevant output from FFMPEG :

From what I know, the resolutions are showing in the wrong order, if 720 was first and 540 after then everything would match up fine. I’m not sure what’s causing this, I am new to the
