• How to make a bot to search song automatically on YouTube after input some words of the song ?

  30 juin 2021, par SOHAM DAS BISWAS.

  I had made a discord bot using python which plays YouTube songs. It takes the link to play a song I want to make it short. I want to give some words of the song and it will search automatically the song on YouTube and play it for me.

  


  My Code :-

  


  import discord,requests, sys, webbrowser, bs4
import youtube_dl
import os
from dotenv import load_dotenv
import ffmpeg
from discord.ext import *
from discord.ext import commands
from discord.ext.commands import Bot
from discord.voice_client import VoiceClient
import asyncio
@client.command(pass_context=True)                      #====================================Join
async def join(ctx):
    channel = ctx.author.voice.channel
    await channel.connect()
@client.command()                                         #===================================Play
async def play(ctx, url:str):
    song_there = os.path.isfile("song.mp3")
    try:
        if song_there:
            os.remove("song.mp3")
            player.clear()
    except PermissionError:
        await ctx.send("Wait for the current playing music end or use the 'stop' command...")
        return
    await ctx.send("Getting everything ready, playing audio soon, depends on your internet speed...")
    print("Someone wants to play music let me get that ready for them...")
    voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
    ydl_opts = {
        'format': 'bestaudio/best',
            'postprocessors': [{
            'key': 'FFmpegExtractAudio',
            'preferredcodec': 'mp3',
            'preferredquality': '192',
        }],
    }
    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        ydl.download([url])
    for file in os.listdir("./"):
        if file.endswith(".mp3"):
            os.rename(file, 'song.mp3')
    voice.play(discord.FFmpegPCMAudio("song.mp3"))
    
    voice.volume = 100


  


  Please help me to solve this.

  


• FFmpeg how generate a sequence of videos with bash

  27 janvier 2018, par Massimo Vantaggio

  i try to write an .sh that read a folder create a playlist of mp4 files and then generate an only big video with a sequence of all videos find in the folder, and encode it for dash :

  printf "file '%s'\n" ./*.mp4 > playlist.sh
  
  ffmpeg -f concat -safe 0 -i playlist.sh -c copy concat.mp4

  Till now i follow the demux concat official guido to ffmpeg website.
  Without result, also the following give me "more than 1000 frames duplicated between videos of the sequence"

  ffmpeg -f concat -i playlist.sh -c:a aac -b:a 384k -ar 48000 -ac 2 -c:v libx264 -x264opts 'keyint=50:min-keyint=50:no-scenecut' -r 25 -b:v 2400k -maxrate 2400k -bufsize 1200k -vf "scale=-1:432 " out.mp4

  Thanks a lot

• Generate MPEG-DASH segments when requested [closed]

  16 septembre 2024, par John Smith

  Up front disclaimer : this question is almost identical to the one here : Generate single MPEG-Dash segment with ffmpeg but it seems that ffmpeg has updated over time and now the answer provided by Coumeu is no longer accurate.

  


  Using ffmpeg, I am attempting to "lazily create" the segments needed for MPEG DASH playback. I have a static manifest (MPD) which includes SegmentTemplates for 1 video and 1 audio stream.

  


  Only when the endpoints provided in the SegmentTemplate for init or media segments is hit it will generate this segment. In other words, nothing is processed up front.

  


  I am creating the init segment using the following movflags :

  


  +frag_keyframe+faststart+skip_trailer 


  


  I am creating the media segment using the following movflags

  


  +frag_keyframe+default_base_moof+delay_moov+skip_trailer+dash+global_sidx


  


  and the following additional commands any segment type :

  


  -map_metadata -1 -copyts -start_at_zero -map 0:${streamIndex}


  


  This results in playable video with the correct duration, but it seems to be switching fragments quite fast. On average one fragment per second. When I omit the delay_moov flag, the video also starts glitching, like it's stepping over I-Frames.

  


  My observations when I look at the boxes :

  


  

  • earliest_presentation_time (sidx box) is 0 for all segments

  


  • base_media_decode_time (moof->traf->tfdt box) is 0 for all segments

  


  


  I'm looking for either the correct command line to create segments on the fly, or hacky ways to get it done right if ffmpeg doesn't provide it out of the box. Even information about what to look for would be helpful, because my knowledge about mp4 and MPEG-DASH is running out.
