• Discord.py : Access files on the computer of the person who sent a message. Play a song from the local drive of any user on the server

  7 avril 2021, par daDib

  I have a bot that can play music from my computer. Is there a way to play a song from the computer of the person who sent the message ? My thought would be using message.author to somehow access the person's session and get into their drive. Here is my bot. It can join a voice channel, create playlists from local file paths, start a playlist or individual file with stop/pause/play/next/previous controls :

  


  import discord
import os.path
import logging
import asyncio
from os import path

global ready 
global vc
global source
global songQueue
global songIndex
global commandList
global stopPlaylist

ready = False
stopPlaylist = False
songQueue = []
songIndex = 0

logger = logging.getLogger('discord')
logger.setLevel(logging.DEBUG)
handler = logging.FileHandler(filename='D:\DnD\DiscordBot\discord.log', encoding='utf-8', mode='w')
handler.setFormatter(logging.Formatter('%(asctime)s:%(levelname)s:%(name)s: %(message)s'))
logger.addHandler(handler)

client = discord.Client()
commands = [
    '!connect\nConnect to a voice channel by channel id. Use !channels to find the desired id.\nExample Command: !connect 827202170973323305\n\n',
    '!channels\nLists all voice channels and their connection id.\n\n',
    '!add\nAdd a file path to the playlist.\nExample Command: !add D:\\DnD\\DiscordBot\\mySong.mp3\n\n',
    '!delete\nDeletes the last song added to the playlist.\n\n',
    '!view\nDisplays the current playlist, in order.\n\n',
    '!playlist\nStarts the playlist from the beginning, or optionally add a number as the start position.\nExample Command: !playlist 3\n\n',
    '!playSong\nPlays a specified file.\nExample Command: !playSong D:\\DnD\\DiscordBot\\mySong.mp3\n\n',
    '!next\nPlays next song in playlist.\n\n',
    '!prev\nPlays previous song in playlist.\n\n',
    '!stop\nStops all music song. Playlist will restart from the beginning.\n\n',
    '!pause\nPauses the current song. Restart with !resumeSong.\n\n',
    '!resume\nResumes the current song.\n\n'
    '!status\nLets you know if the bot thinks it is playing music.'

• Using FFMPEG, how do we add subtitles in the black bar area or under the video ?

  26 septembre 2020, par DunceDancer

  I followed these steps :

  


  


  1. Added the black bars

     


     -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080 :(ow-iw)/2 :(oh-ih)/2,setsar=1" Source :How to add black borders to video

     


  


  2. Added the subtitles ("burned" it into the video)

     


     ffmpeg -i "imput.mp4" -lavfi "subtitles=subtitles.srt:force_style='Alignment=0,OutlineColour=&H100000000,BorderStyle=3,Outline=1,Shadow=0,Fontsize=18,MarginL=5,MarginV=25'" -crf 1 -c:a copy "output.mp4" Source : ffmpeg subtitles alignment and position

     


  


  


  Now I am stuck as to how to place the subtitles under the video or in the black screen.

  


  Edit : Screenshot added to clarify

• FFMPEG Replacing black color fragments with alpha channel transperency

  31 décembre 2017, par kostya572

  I have "file.mov" video. It has a lot of blank black color fragments that have different durations.

  I need to replace black color fragments that durates more than 5 seconds with transparency ? Is that possible to add some alpha channel for that purpose ?
