• Discord bot returns ffmpeg error despite being added to PATH

  22 février 2024, par Sam

  I am creating a Discord bot to play music via Youtube as practice with APIs. Every time I run the command to play a Youtube video I am met with "ffmpeg was not found". I have downloaded ffmpeg (as I'm on Windows) and moved the folder to my C : drive. Once done, I've added it to the path within environment variables. The error persists.

  


  

  • I've added ffmpeg to my PATH as described in this video.

  


  • Additionally, I've found forums where the suggested answer is to add ffmpeg to your PATH.

  


  


  In command prompt, if I type "ffmpeg" it returns "'FFmpeg' is not recognized as an internal or external command, operable program or batch file."

  


  Here is my code :

  


  from typing import Final
import os
from dotenv import load_dotenv
from discord import Intents, Client, Message
from responses import get_response
import asyncio
import yt_dlp
import discord

#Step 0: Load our token from somewhere safe
load_dotenv()
#Final decorator makes it so that this cannot be overwritten or have subclasses
TOKEN: Final[str] = os.getenv('DISCORD_TOKEN')


voice_clients = {}
#Settings for the video download.
yt_dl_opts = {'format': 'bestaudio/best'}
ytdl = yt_dlp.YoutubeDL(yt_dl_opts)

#Settings for ffmpeg. 
ffmpeg_options = {'options': '-vn'}

# Step 1: Bot Setup - activate intents
intents: Intents = Intents.default()
intents.message_content = True #NOQA
client: Client = Client(intents=intents)

#Step 2: Message Functionality
async def send_message(message: Message, user_message: str):
    if not user_message:
        print('Message was empty because intents were not enabled... probably')
        return
    
    # The := "Walrus Operator" is used to prompt for input.
    if is_private := user_message[0] == '?':
        user_message = user_message[1:]
    
    try:
        response: str = get_response(user_message)
        await message.author.send(response) if is_private else await message.channel.send(response)
    except Exception as e:
        print(e)

#Step 3: Handling the startup for our bot.
        
@client.event
async def on_ready() -> None:
    print(f"{client.user} is now running")

#Step 4: Handle incoming messages
@client.event
async def on_message(message: Message) -> None:
    if message.author == client.user:
        return
    
    username: str = str(message.author)
    user_message: str = message.content
    channel: str = str(message.channel)

    print(f"[{channel}] {username}: '{user_message}")
    await send_message(message, user_message)

    if message.content.startswith("!play"):
        try:
            url = message.content.split()[1]
            
            #Handles the voice connection that a bot has to a certain channel
            voice_client = await message.author.voice.channel.connect()
            voice_clients[voice_client.guild.id] = voice_client

            loop = asyncio.get_event_loop()
            data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download=False))

            song = data['url']
            player = discord.FFmpegPCMAudio(song, **ffmpeg_options)

            voice_client.play(player)



        except Exception as err:
            print(err)

# Step 5: Main entry point
def main() -> None:
    client.run(token=TOKEN)

if __name__ == '__main__':
    main()```


  


• cannot open file using avformat_open_input - returns "Cannot open ! Invalid data found when processing input"

  21 juin 2012, par sarsonj

  I am just playing with ffmpeg on iOS 5. I started with something simple, like opening .mov file.

  The code fragment :

  AVFormatContext *pFormatCtx = NULL;
  
  av_register_all();
  
  
  
  NSString* fileName =  [[NSBundle mainBundle] pathForResource:@"test" ofType:@"mov"];
  
  NSLog(@"File exists? %i", [[NSFileManager defaultManager] fileExistsAtPath:fileName]);
  
  NSLog(@"FIle name: %@", fileName);
  
  char errbuf[256];
  
  
  
  int ret = avformat_open_input(&pFormatCtx, [fileName UTF8String], NULL, NULL);
  
      if(ret != 0) {
  
          av_strerror(ret,errbuf,sizeof(errbuf));
  
          NSLog(@"Cannot open! %s", errbuf);
  
      } else {
  
          NSLog(@"Opened!");
  
      }

  The test.mov exists in my bundle and avformat_open_input is trying to open it - but the avformat_open_input always returns (when decoded error code to string) :

  Invalid data found when processing input.

  (the error code when the file is missing is another text, I tried it).

  I suppose that maybe ffmpg is not compiled with .mov support, but I am not able to open any movie file. I tried to look at ./configure options, but didn't find any hint.

• ffmpeg avcodec_open2 returns -22 if I change my speaker configuration

  5 octobre 2014, par pacificator

  I keep having a strange issue lately.
  Depending on how I set up my audio configuration in windows ( stereo/quad/5.1 ), a ffmpeg call to avcodec_open2() fails with error -22 or just works.
  Not being able to find much about that error, I thought I should ask about it here.
  The main flow goes like this :

  c = st->codec;
  
  avformat_alloc_output_context2(&oc, NULL, NULL, "video.mpeg");
  
  oc->fmt->audio_codec = AV_CODEC_ID_MP2;
  
  AVDictionary* dict = NULL;
  
  ret = av_dict_set(&dict, "ac", "2", 0);
  
  c->request_channels = 2;
  
  
  
  ret = avcodec_open2(c, codec, &dict); //HERE IT FAILS WITH -22 if speaker configuration  is not stereo

  The codec context ’c’ is set up like this in a stream :

  st = avformat_new_stream(oc, *codec);
  
  c = st->codec;
  
  c->channels     = 2;
  
  c->channel_layout = AV_CH_LAYOUT_STEREO;
  
  c->sample_fmt   = AV_SAMPLE_FMT_S16;
  
  c->codec_id     = codec_id;

  Most of it is copied from their one of the muxing examples found in the documentation.
  Everything works as expected if in windows I have set the output to stereo.

  If I set my speaker configuration to 5.1 ( 6 channels ), avcodec_open2 fails with error -22.

  So I have a hard time understanding what am I doing wrong. Normally it should not be any relationship between my speaker configuration and the result of avcodec_open2.

  Are there some other parameters that I need to set ?
