• FFMPEG stream desktop to youtube

  3 juillet 2018, par user8222409

  There are tutorials out there on how to stream to youtube using ffmpeg, and I have that part of the code done.
  However, I do not know how to stream the desktop in ffmpeg. The tutorials online only show usage of web cams. Anyway, What software do I use to capture the screen and stream using ffmpeg.
  Can I do this natively in ffmpeg. If so, how ?

  what I have so far is

   ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i pipe:0 -c:v copy -c:a aac -ab 128k -g 40 -strict experimental -f flv -r 30 rtmp://a.rtmp.youtube.com/live2/$1

  where the $1 is a command line param.

• ffmpeg : smooth, stable timelapse videos from normal speed videos

  18 mars 2015, par est

  For a one hour dash cam video in normal speed, is it possible to create a smooth timelapse video from it ?

  Most tutorials online I found about "timelapse + ffmpeg" are with static jpeg files combined into a timelapse video. These often result jiggle between frames, are the any specific parameters which would make the video looking very smooth & stable ?

  Should I just setpts=0.5*PTS for the trick ? Any must-have or little-known tricks ?

• Hosting music bot on heroku

  2 mars 2021, par itsmaxplayz

  I have made a discord bot on discord.py rewrite which plays music in a voice channel. The code is as follows :

  


  def search(query):

    with ytdl:
        try:
            requests.get(query)
        except:
            info = ytdl.extract_info(f"ytsearch:{query}", download=False)['entries'][0]
        else:
            info = ytdl.extract_info(query, download=False)
    return info, info['formats'][0]['url']

ydl_opts = {
    'format': 'bestaudio/best',
    'quiet': True,
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192',
    }],

}

ytdl = youtube_dl.YoutubeDL(ydl_opts)

FFMPEG_OPTS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}

@client.command(aliases=['p'])
async def play(ctx, *, url):
    channel = ctx.message.author.voice.channel
    voice = get(client.voice_clients, guild=ctx.guild)
    if voice and voice.is_connected():
        pass
    else:
        voice = await channel.connect()
        await ctx.send(f'Successfully joined `{channel}`')

    if voice.is_playing():
        await ctx.send('Already playing a song. Try using -q or -queue to queue a song 
    :thumbsup:')
    else:
        await ctx.send(f'Searching for: `{url}` :mag_right:')
        video, source = search(url)
        voice.play(FFmpegPCMAudio(source, **FFMPEG_OPTS))
        voice.is_playing()
        await ctx.send(f'Playing: :notes: `{video["title"]}` - Now!')


  


  It works locally but when I upload the code to heroku (I use github to push the code to heroku), the bot does not come online.
These are the libraries that I imported in the code :

  


  import discord
import json
import random
import youtube_dl
import requests
import os
from discord.ext import commands
from discord.utils import get
from discord import FFmpegPCMAudio
import ctypes
import ctypes.util


  


  I have installed the ffmpeg buildpacks as I saw in another post on this website but the bot doesn't come online.
