• How can I download videos from reddit using praw

  9 octobre 2023, par rabbibillclinton

  So I want to download videos from reddit, I've seen projects on github but I'm very new to python and don't know how it works, if someone could explain I'd appreciate it, I found this project It works but it seperates audio and video and I want it all in one, I think you can combine those using ffmpeg but I don't know how that works either, also how do I configure some of this stuff like where the videos save and quality, here's my code.

  


  from redvid import Downloader
import praw

reddit = praw.Reddit(client_id = "a", client_secret = "b", user_agent = "c")

subreddit = reddit.subreddit("learnpython")
hot = subreddit.hot(limit=5)

downloader = Downloader(max_q=True)

for submission in hot:
    downloader.url = submission.url
    reddit.download()


  


• How to use ffmpeg-python library to download a Twitch VOD with a link retrieved using the streamlink library

  28 octobre 2020, par Daniel Norfolk

  This is the whole code, for easy reference :

  


  import urllib.request
import streamlink
import ffmpeg
stream_url = streamlink.streams("https://www.twitch.tv/videos/783301562")['best'].url
print(stream_url)

try:
    urllib.request.urlretrieve(stream_url, "vod.m3u8")
except Exception as e:
    print(e)

stream = (
    ffmpeg
    .input('vod.m3u8')
    .output('output.mp4')
    .run
)
print(stream)


  


  I am looking at a way of downloading Twitch VODs. I started with the link to a VOD : https://www.twitch.tv/videos/783301562 . I then used the code :

  


  stream_url = streamlink.streams("https://www.twitch.tv/videos/783301562")['best'].url
print(stream_url)


  


  This gave me a new link which, when I go to this link it downloaded a file with a '.m3u8' extension. This link is : https://dqrpb9wgowsf5.cloudfront.net/ab3654a5992fbfa52ccb_briziana_40240109614_1603789265/chunked/index-dvr.m3u8

  


  From here, I first tried to put the link directly into the following code :

  


  stream = (
    ffmpeg
    .input(stream_url)
    .output('output.mp4')
    .run
)
print(stream)


  


  This didn't output any mp4 file but did give the output :

  


  


  >

  


  


  I then added the following code to download the file, I also change the ffmpeg code to use the downloaded file rather then the url :

  


  try:
    urllib.request.urlretrieve(stream_url, "vod.m3u8")
except Exception as e:
    print(e)

stream = (
    ffmpeg
    .input('vod.m3u8')
    .output('output.mp4')
    .run
)
print(stream)


  


  This gave the same result, no mp4 file with the same output as above. Any help would be greatly appreciated !

  


• Unable to download a file using youtube_dl

  22 octobre 2020, par perkymaster

  I am trying to play music from a bot using ffmpeg and youtube_dl by making using of discord.py but it seems that I am unable to download the file

  


  Here is my code :

  


  voice = get(client.voice_clients, guild=ctx.guild)

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

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    print("Downloading audio now \n")
    ydl.download([url])

for file in os.listdir("./"):
    if file.endswith(".mp3"):
        name=file
        print(f"Renamed File: {file}\n")
        os.rename(file, "song.mp3")

voice.play(discord.FFmpegPCMAudio('song.mp3'), after=lambda e: print(f"{name} has finished playing"))
voice.is_playing()
voice.source=discord.PCMVolumeTransformer(voice.source)
voice.source.volume= 0.7

nname = name.rsplit("-", 2)
await ctx.send(f"Playing {nname}")
print("Playing \n")


  


  Nothing seems to happen, the bot is not playing any music.

  


  I am new to this, can anyone help ?
