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.

Que fait exactement ce script ?
18 janvier 2011, parCe script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
Installation de dépendances de MediaSPIP
Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :
Les outils de base pour pouvoir installer le reste des dépendances Les outils de développements : build-essential (via APT depuis les dépôts officiels) ; (...) -
Automated installation script of MediaSPIP

You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.

Video Encoded using FFmpeg is not being played in Azure Kinect Viewer
4 octobre 2023, par Ashutosh SinglaI captured a video using a
Kinect Azure SDK
device and extracted the RGB (Color) track usingMKVToolNIX
. I could playback this RGB track usingAzure Kinect Viewer (v.1.4.1)
. However, when I encode a video usingFFmpeg
, the command is given below. I can not playback the video using Azure Kinect Viewer. I get a message :



Failed to open Recording




ffmpeg -i .\RGB.mkv -c:v libx264 -preset veryfast -crf 18 -c:a aac -b:a 128k RGG_Enc.mkv



I tried with different codecs (H.264, H.265, VP9, VP10, MJPEG) and different settings, but could not play the video in
Azure Kinect Viewer
. Can someone suggest to me what to do ?

Here is the output of the
FFprobe
for the original video.

Command raised an exception : NameError : name 'player' is not defined
20 mars 2023, par baartysI finally got myself a hosting for my project, but got into an error and I don't know how to resolve it.
I ran command !play to start streaming in vc, but I got this error :


2023-03-19 18:36:04 INFO discord.client logging in using static token
2023-03-19 18:36:04 INFO discord.gateway Shard ID None has connected to Gateway (Session ID: f983009c9f2881b87ee119278692efc9).
Eurobeat Radio is running!

 File "/home/container/radio.py", line 44, in play

The above exception was the direct cause of the following exception:

I tried running it on my pc and that was without error, but once it was on the hosting it ran in to the error up the page.


Here is the code :


import discord
import urllib.request, json 
from discord import FFmpegPCMAudio
from discord.ext import commands
from discord.ext import tasks
client= commands.Bot(command_prefix="er!", intents=discord.Intents.all(), help_command=None)

@tasks.loop(seconds=10.0)
async def my_background_task():
 """Will loop every 60 seconds and change the bots presence"""
 with urllib.request.urlopen('https://api.laut.fm/station/eurobeat/current_song') as url:
 data = json.load(url)
 global namestatus
 global artiststatus
 namestatus = data['title']
 artiststatus = data['artist']['name']
 await client.change_presence(activity=discord.Activity(type=discord.ActivityType.listening, name="Eurobeat FM"))
 await client.change_presence(activity=discord.Game(name="Para para dancing ~"))
 await client.change_presence(activity=discord.Activity(type=discord.ActivityType.listening, name=f"{namestatus} by {artiststatus}"))


@client.event
async def on_ready():
 print('Eurobeat Radio is running!')
 await client.wait_until_ready()
 my_background_task.start()


@client.event
async def on_voice_state_update(member, prev, cur):
 if client.user in prev.channel.members and len([m for m in prev.channel.members if not m.bot]) == 0:
 channel = discord.utils.get(client.voice_clients, channel=prev.channel)
 await channel.disconnect()

@client.command(aliases=['p', 'pla', 'join', 'j'])
async def play(ctx, url: str = 'http://stream.eurobeat.xyz'): 
 channel = ctx.message.author.voice.channel
 global player
 try:
 player = await channel.connect()
 except:
 pass
 player.play(FFmpegPCMAudio('http://stream.eurobeat.xyz'))
 embedVar = discord.Embed(title="Started Playing!", color=discord.Color.random())
 await ctx.send(embed=embedVar)



Would be very grateful for your help !
