• 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
2023-03-19 18:36:04 INFO     discord.gateway Shard ID None has connected to Gateway (Session ID: f983009c9f2881b87ee119278692efc9).

  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 !

  


• Vitamio Media Player License Requirements

  27 mai 2015, par Amanda Fernandez

  I have successfully integrated vitamio project in my app and it works perfectly. But I’m not clear about its licence. I found the project in github. It uses ffmpeg library and some of the files have apache license. So can I use, vitamio for enterprise app without the license ? Or license is mandatory. ?

• Returns wrong frame while seeking in FFMPEG Player

  5 février 2015, par user543

  I have implemented an audio player which supports all the formats using FFMPEG. But while seeking the audio, the application is getting the wrong frame at that target duration. Here is my code for the seek functionality.

           int64_t seekTime = av_rescale_q(seekValue * AV_TIME_BASE,
  
                      AV_TIME_BASE_Q,
  
                      fmt_ctx->streams[seekStreamIndex]->time_base);
  
  
  
              int64_t seekStreamDuration =
  
                      fmt_ctx->streams[seekStreamIndex]->duration;
  
  
  
              int flags = AVSEEK_FLAG_BACKWARD;
  
              if (seekTime > 0 && seekTime < seekStreamDuration)
  
                  flags |= AVSEEK_FLAG_ANY;
  
  
  
              int ret = av_seek_frame(fmt_ctx, seekStreamIndex, seek_target,
  
                      flags);
  
  
  
              if (ret < 0)
  
                  ret = av_seek_frame(fmt_ctx, seekStreamIndex, seekTime,
  
                          flags);
  
  
  
            avcodec_flush_buffers(dec_ctx);

  It is working fine for most of the songs.
  But some of the mp3 songs are getting the wrong timespan.

  For instance : If the song total duration is 2 minutes, if I play the song without seeking it works fine. But while playing, if we seek the song to some position, this will make the song ends with 2 mins and 10 seconds.

  I am getting this issue with only mp3 songs. I am using FFMPEG 2.1. The code for the seek functionality is working fine on FFMPEG 0.11.1.

  Please provide any information about this issue.
