• Command raised an exception : NameError : name 'player' is not defined

  20 mars 2023, par baartys

  I 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

  File "/home/container/radio.py", line 44, in play
    player.play(FFmpegPCMAudio('http://stream.eurobeat.xyz'))

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 !

  


• Video Encoded using FFmpeg is not being played in Azure Kinect Viewer

  4 octobre 2023, par Ashutosh Singla

  I captured a video using a Kinect Azure SDK device and extracted the RGB (Color) track using MKVToolNIX. I could playback this RGB track using Azure Kinect Viewer (v.1.4.1). However, when I encode a video using FFmpeg, 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.

  This example video contains only one channel (RGB) from the original video. I am able to play this video using Azure Kinect Viewer.
