• 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 :

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 !

  


• ffmpeg segments only the first part of my audio file

  30 juin 2012, par hammat

  I'm implementing a http live streaming server to send audio file to iOS devices.
  No problem with Apple's tools, mediafilesegmenter, my files are valid and it works fine.

  I'm trying now to segment the same file using ffmpeg. I've downloaded the last stable version which is the 0.10.2 for now.

  Here is how I try to segment my mp3 file :

  ./ffmpeg -re -i input.mp3 -f segment -segment_time 10 -segment_list outputList.m3u8 -acodec libmp3lame -map 0 output%03d.mp3

  It starts the mapping like expected but finish with only one .mp3 file.

  Did I miss something in the process ?
  Thanks in advance.

  edit

  Ok here is my latest command line :

  ffmpeg -i input.mp3 -c:a libmp3lame -b:a 128k -map 0:0 -f segment -segment_time 10 -segment_list outputlist.m3u8 -segment_format mp3 'output%03d.mp3'

  It still gives me only one file but the file is the hole song, not only one part.
  Here is the output of ffmpeg :

• Faster way of getting number of key frames than "show_frames" in ffprobe ?

  19 novembre 2016, par Will Tower

  I’m making a little in-house utility using ffmpg and ffprobe. Works fine and does what is needed : give a count of the number of key frames in a video file plus some other details.

  Alas, with the large video files this will be used on it can take many seconds for show_frames to return – and I then have to parse the JSON dump of frame data and keep a running count of the total key frames.

  Is there a faster way ? Perhaps it is listed in the "stream" or "format" data dumps and I am not recognizing what it is being called ? I’ve been through the ffmpg and ffprobe docs and didn’t find anything else.
