• machine hangs during ffmpeg command execution [closed]

  15 décembre 2023, par Tejas

  I'm running this ffmpeg command that does multiple trims on input video and concats those trims to generate output.

  


  ffmpeg -i https://d8r14y803bnlk.cloudfront.net/usetldr/2736037/u/796/st/5a919413ff884892bbfffcd0671687a9/p/67c1a16438bf4bb78b785557f4cef7ef/OJx1SIKTNbbGHmQfKT4C_render.mp4 -filter_complex "[0:v:0]trim=start=0.0:end=4.289,setpts=PTS-STARTPTS,format=yuva420p[0v];[0:v:0]trim=start=4.84:end=1034.7,setpts=PTS-STARTPTS,format=yuva420p[1v];[0v][1v]concat=n=2:v=1:a=0" -crf 18 -an -preset ultrafast -y /tmp/8TZeqB3Z6h.mp4


  


  This command works fine on my M1 mac but hangs EC2 instances (c5.4xlarge).

  


  I'm using ffmpeg version 6.1-static https://johnvansickle.com/ffmpeg/  Copyright (c) 2000-2023 the FFmpeg developers built with gcc 8 (Debian 8.3.0-6) on EC2.

  


  Any idea why this could be happening ?

• 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 !
